Belize's weather follows a simple pattern with two complications. There is a dry season and a wet season, the wet one overlaps the Atlantic hurricane season, and the south of the country receives far more rain than the north. For a visitor, the month matters, but so does where in Belize you are.
We fly year-round. In the rainy season the pilot in command decides; if weather stops a flight, it is rescheduled at no cost.
The dry season
Roughly from February to May, reliably drier, with calm seas and the clearest water on the reef.
March to May is the driest and hottest stretch. Inland, it gets properly hot; on the islands, the sea breeze makes it comfortable.
It is also the busiest and most expensive period, especially around Easter.
The transition months
December and January are mostly pleasant but less predictable. Cold fronts from the north, known locally as "northers," bring cooler nights, wind and short spells of rain.
Those same fronts can make boat trips rough for a day or two, so a flexible plan helps.
The wet season
Roughly from June to November, with rain that often comes as heavy showers rather than all-day downpours, especially earlier in the season.
The landscape turns green, the crowds thin, and prices fall.
Many years bring a short drier spell in mid-summer, a pause in the rain worth knowing about but not worth planning around.
Hurricane season
The Atlantic hurricane season runs from June to November, with the greatest risk usually from August to October.
Most weeks pass without a storm, but a system in the area can close the sea and ground small planes for a day or more.
Watch forecasts in that period and keep a buffer day before an international departure, especially from the islands. We check travel advisories before confirming each route and tell you if they change.
North and south are different
The north and the cayes are the drier part of the country. Ambergris Caye and Caye Caulker have the most reliable weather.
The south is much wetter. Placencia gets noticeably more rain, and the far south around Punta Gorda, 36.6 nautical miles beyond Placencia, is the wettest region of all, lush for a reason.
Inland, the Cayo District is hotter in the dry months and cooler at night in the hills.
What the season does to the reef
Visibility is usually best in the dry months, when rivers carry less runoff to the coast.
Rough seas, not rain, are what cancel dives. A showery day can still be a good dive day; a windy one may not be.
Seaweed can wash up on Caribbean beaches in some years, usually in the warmer months. It varies widely from year to year and from beach to beach.
Month by month, roughly
December to January: pleasant, with occasional cool, windy fronts.
February to May: the dry season, calm seas, the busiest period; March to May the hottest.
June to August: the rains begin, the country turns green, a possible mid-summer pause.
September to November: the wettest and quietest, with the highest hurricane risk.
Planning with it
Flights are short, but they are small planes, and weather affects them more than jets. Ambergris is 29.6 nautical miles from the international airport and Placencia 60.3; neither is long, but both can wait out a storm. We show a "from" price per route; the final fare depends on the date, the group and the baggage, and is confirmed in writing before booking.
Mornings are the reliable part of the day in every season.
