Your December weather guide
WarmWeather in Bermuda in December
December in Bermuda suits a mild-weather break rather than a hot beach holiday. Daytime highs average around 21°C, nights stay near 19°C, and about 11 days bring rain. For a UK traveller, that means a welcome change from winter temperatures at home, but not reliable sunshine or warm-water swimming. Go if you are happy spending time outdoors with flexible plans and a light layer; choose another month if heat is the main reason for travelling.

Daytime and night-time in December
The typical December day in Bermuda peaks at 20.7°C, but that is an average: the warmest 10% of days reach 22.5°C or more. Days over 25°C are rare. Nights average 18.7°C; one night in ten drops to 16.2°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest December day here reached 23.9°C (2017-12-07) and the coldest night 13.0°C (1991-12-20).
Rain in December
Wet (more than 8 rainy days): about 11 days with 1 mm or more, 99 mm in total. Year to year it varies a lot - the wettest December was 1997 with 266 mm, the driest 1999 with 32 mm. Humidity averages 71%.
Sea temperature in December
The sea averages 21.8°C - bracing (18-22°c). Depending on the year it ranges from 21.2°C to 22.4°C. For the warmest sea here, come in August (28.0°C).

Around 3.1 hours of sunshine a day (estimated from cloud cover), 9.9 hours of daylight: the sun rises about 07:13 and sets about 17:16 local time in mid-December. Average cloud cover is 68%.
Is December a good time to visit Bermuda?
December is not the strongest month here: warm days and frequent rain. The best months for Bermuda on our scoring are June, July, August; months averaging 25°C or more: Jul, Aug, Sep.
Mild days, with layers for the evening
Bermuda is noticeably milder than London in December, with average daytime highs 13°C higher. That makes walking and spending time outside more appealing without the demands of strong summer heat. Light clothing is a sensible starting point, but pack a jumper or light jacket rather than treating this as a summer trip. Average nights are mild, though the colder ones can fall to around 16°C, so an extra layer earns its place in your luggage. Midday is not usually about avoiding extreme heat: days reaching 25°C are absent from the December figures. This suits travellers who prefer comfortable temperatures to hot afternoons.
Plan around rain and modest sunshine
The catch is that mild does not mean sunny. December has about 3.1 hours of sunshine within 9.9 hours of daylight, so do not build the trip around long sessions in the sun. Rain is a meaningful part of the month, and a light waterproof is more useful than a suitcase packed only for dry weather. Keep outdoor plans flexible and use brighter spells when they come, rather than committing every day to weather-dependent activities. The figures do not promise a washout, but they do make December a weaker fit for anyone whose main aim is consistent beach weather after a UK winter departure.
