Traveller notes on Belize City in May
Notes from nearby Caye Caulker (33 km away)
Belize City doesn't have its own notes for May yet — these are about Caye Caulker, close enough to share the season.
Caye Caulker-forum threads on May weather call it hot and humid, high 20s to low 30s Celsius with humidity high enough to make it feel warmer than the number alone suggests. Precipitation totals are described as low for the month, but posters note a few showers are still likely, usually overnight, early morning, or a brief afternoon burst rather than a washed-out day. May specifically marks the tail end of the low-rain season, the last stretch before the wetter pattern that starts in June takes over. Wind is called a non-issue this month, one less thing to plan around. The record: 31.2C days feeling like a sticky 37C, 26.5C nights, 73mm across 14.5 days, an 82 percent humidity, a 29.4C sea and 11.4 hours of sun.
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.
