Nassau Weather By Month
Nassau sits in the tropics, so the weather question is rarely hot or cold, it is calm or rough. Here is how the year breaks down for anyone planning a pig beach tour.
Short answer
Nassau stays warm year round. December to April is reported as the calmer, drier stretch for boat trips to Rose Island and the Exuma Cays, while hurricane season runs June 1 to November 30. Approximate sea temperatures range from 23 to 25 degrees C in January to 30 to 31 degrees C in August, warm enough to swim in any month.
Nassau weather is a boat-ride question more than a beach-umbrella question. The city sits at the northern edge of the tropics, so every month of the year is swimwear weather by temperate-latitude standards. What changes through the year is wind, sea state, and the chance a tropical system forces an operator to reschedule, and those three things decide whether your swimming pigs trip is a smooth 30-minute hop to Rose Island or a long, bumpy run across open water toward the Exuma Cays. Weather is only half of the planning, so the guide to staying safe in Nassau before a boat day walks you through getting around, choosing tour operators, and what to avoid on the water.
That matters for trip planning because the pig swims sold from Nassau fall into two very different weather exposures. Rose Island sits a reported 20 to 30 minutes by boat from the Nassau waterfront, a short crossing that operators run in a wide range of conditions. Big Major Cay, the famous Pig Beach in the Exumas, is roughly 82 to 86 miles southeast, a one-to-three-hour speedboat run depending on which source you read, and that route is far more sensitive to wind and swell. The same calendar month can be a non-issue for one trip and a cancellation risk for the other.

This guide walks the year month by month in qualitative terms, with approximate sea temperatures from recorded data aggregates, and ties each season back to the pig tours it suits. If you want the deeper comparison of trip types, start with the Rose Island versus Exuma pigs guide or the homepage comparison of every listing.
What Is The Weather Like In Nassau Through The Year?
Nassau has a tropical climate with no cold season, two rough guideposts being a drier, reported-calmer stretch from December to April and a warmer, more humid stretch from May to November that overlaps hurricane season, which runs June 1 to November 30. Air temperatures stay warm enough for swimming every month, and the practical difference between months is wind, humidity, and sea state rather than heat or cold. The same seasonal rhythm applies just south of Nassau in the Exumas, so our month-by-month guide to choosing the best time to visit Exuma can help you weigh sea temperatures, hurricane season, and how to time a pig beach day.
Winter months bring the mildest, least humid air of the year, which is a large part of why they are the busiest for visitors. Spring warms steadily, both in the air and in the water. By June the humidity is noticeable, afternoon showers become more common, and the official hurricane season is underway. Summer and early fall bring the warmest sea temperatures of the year, often 28 to 31 degrees C, along with the highest chance that a named system somewhere in the Atlantic disrupts boat schedules. November and December cool back down, seas settle, and the calm-season pattern returns.
None of this is dramatic in the way mountain or continental weather can be. A summer morning crossing to Rose Island is often flat and gorgeous; a December cold front can still kick up wind. The pattern is a tilt in probabilities, not a rule, and the shorter your boat ride, the less the tilt matters. The site's broader best time to swim with the pigs guide covers how this plays out against crowds and school holidays.
| Season | Months | General character | What it means for a pig tour |
|---|---|---|---|
| Reported calm season | December to April | Lower humidity, frequent fair days, calmer seas reported | Best odds for the long Exuma speedboat run |
| Transition | May, November | Quieter, warming or cooling, variable wind | Good value window, check forecasts |
| Summer | June to August | Hot, humid, warmest water, possible afternoon storms | Short Rose Island crossings usually fine |
| Peak hurricane overlap | September to early November | Highest tropical-system risk of the year | Build flexibility into any boat booking |
When Is Hurricane Season In The Bahamas?
Hurricane season in the Atlantic runs June 1 to November 30, dates confirmed by the National Oceanic and Atmospheric Administration, and it applies to the Bahamas just as it does to the wider basin. Within that window, activity is not even: the heightened-risk stretch is late August through October, while June and July typically see fewer systems. A pig tour in season is still bookable, it simply deserves a free-cancellation policy and a flexible itinerary.
The NOAA seasonal outlook for 2026 is the authority on the dates, and its release predicted below-normal activity for the season, though a quieter forecast is not a guarantee of a quiet week. Individual storms, when they form, are forecast days ahead, which is why operators keep flexible schedules rather than cancelling on speculation.
Practically, the listings on this site state free cancellation, so a September booking is not a gamble in the deposit sense. What hurricane season really changes is the odds of a reschedule. Rough-sea cancellations on the open-water Exuma routes are common in season and operators typically reschedule or refund, as the weather and cancellations guide explains in detail. Rose Island trips, with a crossing of roughly 20 to 30 minutes, are less exposed to open-water conditions.
Between those two exposures sit the multi-stop snorkel combos, which usually head to nearer cays such as Athol Island and Green Cay before the pig stop. The 3 Islands tour from Shore To Shore Bahamas runs 4 hours from $122.85 per person and rates 4.3 from 3,591 reviews, the most reviewed listing on the roster, and its route stays among the near-shore cays east of Nassau (Athol, Rose and Green Cay). The turtle snorkel trip from Delfincharters, 3 hours 30 minutes from $150, rates 4.8 from 1,068 reviews and lists drinks and snacks on board. Both are reasonable picks when the forecast is uncertain, since a shorter, closer route gives an operator more room to adapt.
How Warm Is The Sea Around Nassau Month By Month?
Approximate average sea temperatures around Nassau range from 23 to 25 degrees C in January and February to 30 to 31 degrees C in August, warming steadily through spring and cooling through fall, per recorded data aggregates. Every month of the year is comfortably swimmable without a wetsuit by most visitors' standards, though winter mornings can feel brisk on first entry. These figures are approximate averages, not daily forecasts.
The table below shows the approximate ranges by month. Treat them as a planning guide rather than a promise: shallow beach water at Rose Island on a sunny afternoon runs warmer than the open-water average, and a windy December day can feel cooler than the number suggests. The Ministry of Tourism's official swimming pigs page confirms Big Major Cay as the primary site and notes day trips can be booked from Nassau, and the water never gets genuinely cold.
| Month | Approximate sea temperature (degrees C) | Feel for swimming |
|---|---|---|
| January | 23 to 25 | Refreshing, brisk on entry |
| February | 23 to 25 | Similar to January |
| March | 24 to 26 | Mild |
| April | 25 to 27 | Comfortable |
| May | 27 to 28 | Warm |
| June | 28 to 30 | Warm, bath-like by afternoon |
| July | 29 to 31 | Very warm |
| August | 30 to 31 | Warmest of the year |
| September | 29 to 31 | Very warm |
| October | 28 to 30 | Warm |
| November | 26 to 27 | Mild |
| December | 24 to 26 | Refreshing |
For a beach club day on Rose Island, that curve barely matters, since you are in and out of the water around the pig encounter, lunch, and loungers. The featured Private Beach Club Lunch trip, a 4-hour listing from $129 with a 4.7 rating from 1,680 reviews, describes beach chairs, shaded seating, a Bahamian lunch and paddle boards, the kind of day where sea temperature is a footnote. The same listing appears in the Rose Island pig beach tours guide.

Which Months Give You The Calmest Boat Day?
December to April is reported by operators and tour-focused sources as the calmer, drier stretch for boat trips from Nassau, with lower humidity and fewer strong-wind days, while the Exuma speedboat route is described as rougher in hurricane season or during strong trade winds. May and November are quieter shoulder months with more variable conditions and thinner crowds.
The calm season lines up with peak visitor season, so the trade is fairness of seas against busier boats and beaches. The Exuma run is where this bites hardest: sources describe the open-water crossing as capable of steep, short-period chop in winds above roughly 20 knots, with seasickness risk noted by both operators and reviewers. December to April, and morning departures generally, are described as the preferred windows. Guides on pregnancy, mobility, and back or neck concerns typically flag the speedboat run as unsuitable, so a calm month matters doubly if anyone in your group is sensitive to motion; check the listing for its own policy.
For closer trips the same months help but matter less. A Sandy Toes day, 6 hours from $258 with a 4.7 rating from 1,282 reviews, spends most of its time on Rose Island rather than in transit, so a fresh breeze costs you a kayak session rather than the whole day. The Nassau to Exuma by plane or speedboat guide compares the two travel modes in depth.
The Private Beach Club, Lunch listing is a sensible anchor for a calm-season or shoulder-season plan alike: its 4-hour format keeps the crossing short, the free-cancellation policy is listed, and the 4.7 rating across 1,680 reviews reflects a large pool of guests rather than a handful. If your dates fall in the rougher half of the year, favoring short crossings over long ones is the single easiest weather decision you can make.
What Does Each Month Mean For A Pig Tour?
Each month shifts the experience slightly: January and February bring the coolest, calmest-condition days, March through May warm steadily with good water clarity, June through August deliver the warmest sea and the most sun, and September through November carry the highest reschedule odds before December settles everything back down. No month is a wrong month to book, but each pairs better with one trip type than another.
The table below is a qualitative month-by-month read for planning, anchored to the pig trips on this roster. It deliberately avoids rainfall totals and air-temperature numbers, which vary by source, and sticks to what operators and recorded sea-temperature data support. For how a full day on the water actually unfolds once booked, the day trip to the Exuma pigs walkthrough covers the sequence hour by hour.
| Month | Conditions read | Trip that fits |
|---|---|---|
| January | Cool air by tropical standards, calm seas common, brisk water | Exuma speedboat day, 8 hours from $439 |
| February | Similar to January, quiet islands | Exuma or a Sandy Toes 6-hour day |
| March | Warming, popular with families | 3 Stops catamaran trip, 5 hours 30 minutes from $149 |
| April | Warm water, calm-season tail end | Any Exuma or Rose Island format |
| May | Shoulder month, warming and humid | Rose Island beach club day from $129 |
| June | Warm water, storm season begins | Short Rose Island or 3-hour snorkel trips |
| July | Very warm sea, strong sun | Beach club day with shade and lunch included |
| August | Warmest water of the year, peak humidity | Water taxi option, from $89, 4 hours |
| September | Peak tropical-system overlap | Book with flexibility, favor short crossings |
| October | Still warm, risk easing | Self-drive speedboat, 2 hours from $150 per person |
| November | Quieter, cooling, variable | Turtle snorkel combo, 3 hours 30 minutes from $150 |
| December | Calm season returns, festive crowds | Exuma plane or speedboat day |
One note on the names: the pigs are not native to the Bahamas and how they arrived is not known for sure, with stories commonly told of sailors leaving them or of a shipwreck, per the Ministry of Tourism. The roughly 20 pigs and piglets on Big Major Cay live on an uninhabited cay and receive daily boat visits, in every month of the calendar, which is the strongest weather signal of all: the water is always warm enough and the operators always running. Everything else covered here is indexed on Swim With Pigs Nassau.
How Does Summer Heat Change A Day With The Pigs?
Summer in Nassau means high UV, high humidity, and the warmest sea temperatures of the year, typically 28 to 31 degrees C from June through September, so the challenge flips from wind to sun: hydration, shade, and reef-safe sunscreen matter more than sea state for the short Rose Island crossings. Afternoon showers are possible but usually brief rather than day-ruining.
A summer pig day rewards listings that build in shade and drinks. The 3 Stops catamaran trip from Sail Tomorrow, 5 hours 30 minutes from $149 with a 4.9 rating from 414 reviews, lists a washroom, lunch with vegan and vegetarian options, and a catamaran layout with, in the listing's words, lots of space. The Exuma Island Hopping trip from Born Free Charters, 8 hours from $438.90 rating 4.8 from 688 reviews, lists local beer, lunch at a restaurant, and bottled water. Sun protection is a general recommendation from operators, with reef-safe sunscreen suggested by some.

For families, summer heat argues for the listings with the most land time built in. The Sandy Toes 6-hour day is the longest Rose Island format on the roster, with a full Bahamian barbecue lunch, standard alcoholic beverages, lemonade during lunch service, and snorkel gear against a refundable deposit of USD $10, all listed on its line. Six hours on an island with shade, food, and calm near-shore water is a different proposition from six hours on an open boat.
Is Winter Actually A Good Time To Swim With The Pigs?
Winter, December to April, is reported as the best window for boat conditions around Nassau, with calmer seas and lower humidity, while the sea at roughly 23 to 27 degrees C is the coolest of the year but still comfortably swimmable. The trade-offs are busier boats, festive-season crowds, and water that feels brisk for the first minute, which most visitors stop noticing once they are in.
Winter is when the Exuma day trips earn their price. An 8-hour island hopping day from Born Free Charters or the powerboat trip from Aqua Shores, from $439 rating 4.8 from 536 reviews, both cross the open stretch between Nassau and the Exuma Cays, and December to April gives those runs their best odds of running as scheduled. The listing for the Exuma Escapes 8-hour trip, from $378 per person, describes Allen's Cay iguanas, Compass Cay nurse sharks, Big Major Cay pigs, and a Bahamian lunch, a full itinerary that only pays off when the sea cooperates.

If winter crowds put you off, late April and early May sit in a sweet spot: sea temperatures are already 25 to 28 degrees C, the calm-season pattern is often still in place, and boats are reported quieter before the summer value window opens. Swim With Pigs Nassau exists, in part, because the question of when to go is really a question of which water you will cross, and the shoulder months answer it cheaply.
What Should You Pack For Nassau Weather?
For any pig tour in any month, pack a swimsuit, towel, hat, sunscreen with reef-safe formulation recommended by operators, and dry clothes for the ride back; in winter add a light layer for the boat run out, and in summer add extra water and sun protection for high UV. Operators' bring-and-wear guidance is consistent on these points, and the listing for your specific tour is the place to confirm anything unusual.
Winter boat runs, especially the first hour of an Exuma departure around 8 AM, can feel cool at speed even when the day warms up, so a light shirt or windbreaker earns its spot in the bag from December through February. In summer the sun is the whole story: high UV is reported year round and strongest from spring through fall, and open-water boats offer little shade. Packing notes for every trip type, including what to bring for kids, are gathered in the what to bring and wear guide.
A note on safety around the pigs themselves: pigs can nip when food is present, per traveler and press accounts, so follow your guide's instructions on feeding and interacting, in every season. The is swimming with the pigs safe guide covers this fully.
| Condition you might hit | Months most likely | What to pack |
|---|---|---|
| Brisk morning boat run | December to February | Light layer, windbreaker |
| Strong midday sun | Year round, peak spring to fall | Reef-safe sunscreen, hat, sunglasses |
| Warmest water | June to September | Rash guard optional, extra water |
| Fresh wind on crossings | Any month | Motion-sickness remedy if prone |
| Brief afternoon shower | May to October | Dry bag for phones |

How Does Weather Affect A Cruise Day In Nassau?
Weather on a Nassau cruise day mostly affects the long Exuma boat tours, which are described as tight against standard all-aboard times even in calm conditions, while Rose Island crossings of 20 to 30 minutes leave room for a delayed or rerouted departure; ships dock at Prince George Wharf and all-aboard is typically 30 to 90 minutes before sailing, so a weather-delayed boat is a real risk on full-day formats.
The honest read for cruise visitors is that the long Exuma run and a standard port call are an awkward pairing even before weather enters. Independent listings are the alternative to ship-organized excursions, and excursion menus vary by line and sailing. The safer cruise-day formats are the short ones: the 2-hour self-drive speedboat trip from Cruising Adventures, from $150 per person rating 4.5 from 121 reviews, or the 2-hour Short Pig Swim from Bahamas Water Toys and Tours, from $154 per person rating 4.6 from 68 reviews with unlimited drinks listed on board.
The Nassau cruise port guide and the Rose Island or Exuma from the cruise port comparison cover the timing math in full. In weather terms the rule is simple: the less time your itinerary spends crossing open water, the more of your port call survives a breezy day.
Which Listing Fits Which Season?
Short Rose Island crossings from $75 to $179 suit every month including the hurricane-season overlap, mid-length snorkel combos from $122.85 to $150 add turtle and reef stops in sheltered water, and the full Exuma days from $378 to $439 plus plane options reward the December to April calm season. Matching the crossing length to the season is the highest-value weather decision on this page.
| Listing | Price from | Duration | Weather exposure |
|---|---|---|---|
| Water Taxi, No Meal | $89 per person | 4 hours | Short crossing, all-season |
| Private Beach Club, Lunch (featured) | $129 | 4 hours | Short crossing, all-season |
| 3 Islands, English and Spanish | $122.85 per person | 4 hours | Near-shore cays, all-season |
| Sandy Toes 6-Hour Day | $258 | 6 hours | Island-based, all-season |
| Exuma Island Hopping, Lunch | $438.90 | 8 hours | Open water, calm season |
| Exuma Powerboat Day | $439 | 8 hours | Open water, calm season |
