Traveller notes on Bacalar in December
Other months in Bacalar
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.
