Traveller notes on Belize City in December

Notes from nearby Placencia (111 km away)

Belize City doesn't have its own notes for December yet — these are about Placencia, close enough to share the season.

Regulars are specific a cold front moves in from the north roughly every 7 to 10 days here, each one bringing a real temperature drop and often rain along with it, the coastal town itself running cooler at night and milder in the day than inland spots like San Ignacio. Our row backs that warm, genuinely wet read, 26.3C over 22.2C nights feeling 25C, with a substantial 135.3mm of rain across 22.7 days and humidity at 85 percent. Regulars are consistent hot, sunny stretches between fronts remain the more common experience day to day, evenings staying warm and pleasant rather than genuinely cold even after a front passes through. The sea sits at a warm, swimmable 27.3C. The record: 8.9 hours of sun, a 14.3 kph wind and AQI 30.

Other months in Belize City

Forum posters cite typical August daily highs around 31C (88-90F) with overnight lows near 24C, and describe rain this time of year as most often falling overnight, leaving days sunny and clear more often than not - it seldom rains every day or all day unless a tropical low pressure system moves through. Posters specifically flag mid-August as home to Belize's well-known 'little dry season,' roughly a two-week stretch of notably reduced rainfall within the broader wet season. Posters are consistent that hurricane risk in August itself is low, citing historical records showing only a handful of hurricanes have affected Belize before September in the past century. Posters generally rate August as hot, humid and typically sunny by day for Belize City, with rain concentrated overnight and hurricane risk still modest this early in the season.

Forum posters describe February as more dry than wet, with rain, when it happens, typically falling overnight and leaving fine, sunny days behind - a daily maximum around 28C and overnight lows near 20C are typical, with most days seeing clear, sunny skies. Posters describe humidity as still noticeable, especially right after arrival, but consider February's lower temperatures the key factor that makes that humidity feel bearable rather than oppressive. Posters flag real week-to-week variability from passing cold fronts, which can drop temperatures by a few degrees, though rainfall stays consistently lower than January and isn't something to plan around. Posters generally name February through April as Belize's driest stretch of the year, with February specifically rated as an excellent time to visit.
