Het weer in Bacalar (Laguna Bacalar) in april

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.

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.
