Traveller notes on Nassau in December
Other months in Nassau
Regulars are specific that cold fronts pass through two or three times a week this month, a warm day typically arriving just before one hits, followed by a few genuinely cold and windy days behind it - shorts and tank tops for daytime with a sweater kept for evening the standard advice. Our row backs that mild, genuinely wet and windy read, 26.8C over 18.9C nights, with 48mm of rain across 8.7 days and a real 29.9 kph wind. Regulars are consistent the sea itself runs noticeably cooler than summer, comparable to a June swim at the Jersey shore rather than a bath-warm Caribbean dip, brisk rather than unswimmable. Overall this remains a genuinely variable month, warm and breezy some days, properly cool and windy on others. The sea sits at 24.5C. The record: 9 hours of sun, humidity 72 percent and AQI 41.
Nassau-forum threads on July weather confirm it's one of the hottest stretches of the year, daytime temperatures in the low-to-mid 90s Fahrenheit with a heat index that regularly clears 100. Thunderstorms are a real daily possibility, roughly a coin-flip most days, but posters are consistent that it's typically a quick twenty-minute pop-up rather than an all-day washout, and conditions are described as genuinely localized - rain falling in one part of the island while another stays clear. One long-time visitor with twenty-plus years of July trips reports losing an entire day to rain only once or twice. Regulars call July a favorite month since days run longest and the water stays warm. Hurricane season is technically underway but its real peak doesn't arrive until mid-September. The record: 32.9C days feeling like a punishing 38C, 25.6C nights, 90mm across 15.7 days, 76 percent humidity, a 31.3C sea and 11.9 hours of sun.
Nassau-forum threads on November weather call it a genuine sweet spot: daytime temperatures in the upper 70s to low 80s Fahrenheit, an ocean still warm enough to swim comfortably, and humidity well below the sticky summer months - shorts and tank tops are fine most days, with the sun noticeably less intense than in high summer. Precipitation is possible but not the story, mostly arriving with a passing cold front rather than as a standing feature; the Northern Bahamas typically see one such front move through in the last week of the month, cool enough by local standards that a light jacket or sweatshirt covers it at night. The record: 29.2C days feeling like 31C, 22C nights, 62mm across 7.9 days, 73 percent humidity and 9.5 hours of sun - warm, breezy, and about as easy a month as the island has.
April in Nassau splits down the middle and the dividing line is the wind. The windy stretch here runs from about mid-December to mid-March on the forum's account, driven by the pressure gradient over the northern Bahamas, and their advice to anyone who dislikes it is to come from mid-April onwards. Early April still catches it - one cruise could not call at its private island for the swell, and a trip to the out islands met near gale-force wind, high seas and cold water - while the end of April into early May is the part they recommend, with highs in the 80s Fahrenheit and the sea warming towards 80. Our row keeps 28.5 kph across the whole month. The record: 29.2C days that feel like 31C, 21.7C nights, 7.9 precipitation days carrying 44.3mm and a 26.5C sea.
