Traveller notes on Caye Caulker in October

Notes from nearby San Pedro (21 km away)

Caye Caulker doesn't have its own notes for October yet — these are about San Pedro, close enough to share the season.

San Pedro's forum says October weather can be genuinely nice, with wind being the bigger day-to-day factor than rain itself - a typical day still runs sunny, hot and humid. When rain does show up it's usually overnight or a brief afternoon shower, rarely an all-day downpour, and posters were consistent it rarely derails plans. October is technically the tail end of hurricane season, but actual hurricanes hit only about once every five years on average, and several locals specifically recommended the month for the slow-season deals and quieter island.

Other months in Caye Caulker

January is the coolest month here and regulars describe the mechanism rather than the average: from December to March a cold front crosses every ten to fourteen days and lasts a day or two, bringing wind, cloud and sometimes rain - and sometimes no rain at all. What it does bring is wind, which is the part that spoils a snorkelling day. Our row fits: 78mm across 15.4 days is five millimetres a time, and all-day rain is as rare as they say. Days reach 27.4C and feel like 31C at 84 percent humidity; nights fall to 22.4C, or lower behind a front. The sea is 26.7C. The record: 9.4 hours of sun, a 17.3 kph wind and AQI 41.

Caye Caulker-forum threads on July weather describe a real gap between the forecast and lived experience: apps often show rain and storms every single day of the month, but posters consistently report that isn't what actually happens on the ground. The more typical pattern is a single rain event roughly once a week, usually landing in the very early morning hours and clearing up well before 9am, leaving the rest of the day sunny and calm. Some visitors describe entire stretches with barely any rain at all, calling it some of the year's most beautiful weather; others get the more standard hot-and-humid version with an occasional storm. All-day rain is described as genuinely rare rather than typical. Heat and humidity both run high regardless of the rain pattern, the more consistent discomfort across every account. The record: 30.7C days feeling like a punishing 37C, 26.4C nights, a notably high 144mm across 24.6 days, 85 percent humidity, a 30C sea and 11.2 hours of sun.

Caye Caulker-forum threads on November weather are consistent that it's technically inside the rainy season but rarely feels like it day to day: rain doesn't fall every day or all day, arriving instead as a brief shower, often overnight, so mornings tend to stay clear and sunny. Posters call the month variable but mainly sunny overall, and the sea itself stays calm and warm, genuinely comfortable for swimming even with rain technically on the books. The general consensus is not to overthink November's rainy-season label - the actual lived experience most visitors report is closer to a normal tropical month with an occasional wet interruption than a washout. The record: 28.7C days feeling like a sticky 34C, 23.6C nights, a notably high 192mm across 19.6 days, 86 percent humidity, a 28.4C sea and 9.2 hours of sun - wetter by the numbers than the forum's easygoing framing suggests.

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.
