Traveller notes on San Pedro in July
Notes from nearby Caye Caulker (21 km away)
San Pedro doesn't have its own notes for July yet — these are about Caye Caulker, close enough to share the season.
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.
Other months in San Pedro
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.
Forum posters consistently describe April on Ambergris Caye as hot and dry, with average daily highs around 31C and overnight lows around 24C. Posters are direct that although rainfall is very low this time of year, a few days can still bring rain - typically overnight or early morning, or a brief afternoon shower, with the rest of the day staying sunny and fine. Posters consistently emphasize it doesn't rain every day and there are no all-day downpours to worry about. Posters generally rate April as one of the better months to visit San Pedro, with good, reliable weather for diving and beach days.
