מזג האוויר במרידה בדצמבר

Forum posters describe July in Mérida as sitting within the rainy season but functioning as something of a mini-dry-season, with fewer stormy days than June or September - typical rain here is a late-afternoon or early-evening downpour lasting 30-90 minutes rather than an all-day event, unless a major storm system moves through. Posters cite daytime temperatures around 34-37C with high humidity comparable to Florida, and note that with the heat and humidity combined, the real feel can push past 110F. Posters consistently flag July and August as the busiest local vacation period, with residents flocking to nearby Progreso and the coast as schools and many workplaces close for a couple of weeks. Posters generally rate July as hot and humid but manageable, with rain a predictable late-day event rather than a constant disruption.

December to February is the forum's window for Mérida, and January sits comfortably inside it — near 29°C by day and 20 overnight, so most visitors are in shorts through the afternoon while wanting a light sweater after dark. Rain is down to four days. The pattern regulars actually warn about is the norte: roughly every couple of weeks a cold front pushes down from the north, bringing cooler air and light drizzle that can hang about for two to five days. Out at the coast the humid breeze makes those evenings feel chillier than the number suggests — long trousers, not just a jumper.
