Meteo Bacalar (Laguna Bacalar) in febbraio

February is inside Caye Caulker's busy stretch, January to April, and the forum's reassurance is about forecasts rather than weather: a late-February visitor whose app promised rain nearly every day got about thirty seconds of it. Our row says the same thing in figures - 13.5 precipitation days carrying 42.9mm between them. Seaweed is the real variable and it is wind-driven: in winter a northerly often pushes it back out to sea, and how much lands varies day to day and property to property, because the clearing is done by whoever owns the frontage. Sargassum season proper starts mid-February to mid-March, lightly at first. The record: 28.1C days that feel like 32C, 23.2C nights, 10.1 hours of sun and a 26.6C sea.

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.
