Meteo Bacalar (Laguna Bacalar) in settembre

Forum posters are direct that September sits within Belize's wet and hurricane season, with one of the higher rainfall totals of the year, though actual year-to-year experience varies. Posters consistently describe rain here as coming mostly overnight or as a brief afternoon shower, with days staying sunny and clear rather than washed out - one detailed week-long September stay reported rain only at night or early morning, with nighttime thunderstorms over the ocean described as a genuine visual highlight rather than a nuisance. Posters are consistent that despite hurricane-season nerves, September is actually one of the more beautiful times of year here, with real crowd relief given how much quieter the island runs, though posters note some businesses do close for the season.

Yucatán coast forum threads describe July as hot and humid with daytime highs around 33C, right around when the 'canícula' - the year's hottest, driest stretch - typically begins in mid-month. It's technically wet season, but posters were consistent that forecasts predicting daily storms don't match reality; when rain does show up it's usually overnight or a brief afternoon shower rather than an all-day event. Hurricane risk in July specifically stays low, picking up more in the following months.

Forum posters place January inside the more pleasant November-April stretch here - less humid and hot than summer, and correspondingly fewer mosquitoes around the famous Lagoon of Seven Colors. Days are typically sunny and warm, with pleasantly cool nights, though posters note a passing cold front can occasionally bring a properly chilly night and grey, drizzly skies - February sees this more often than January, but it's not ruled out either month. Hurricane risk, a real consideration in the surrounding region from June through November, is essentially off the table by January, one more reason posters favor this month for lagoon swimming and boat trips.
