מזג האוויר בPanajachel (Lake Atitlán) בינואר

January on the lake is warm days and genuinely cool nights - the forum's figures for San Pedro are highs of 77 to 81F against lows of 52 to 56F, with the altitude, 4,500 to 5,000ft, doing the work at both ends. What actually shapes a day here is the Xocomil, the wind that gets up in the afternoon: mornings on the lake are calm, and after about four it is choppy enough to make a lancha ride rough and a small boat unwise. So kayaking and crossings are morning business, and the public lanchas stop at dusk, around six. The water is on the cold side from November to February. The record: 23.4C days, 15.7C nights, 4.3 precipitation days carrying 14.9mm and 10.4 hours of sun.

Lake Atitlán/Panajachel forum threads describe August as a genuine mixed bag - some stretches bring very little rain for weeks, other times it rains most afternoons for an hour or two, with tropical-storm-driven multi-day rain the real exception rather than the norm. The typical daily pattern posters described: gorgeous mornings, then a chance of rain arriving after around 2pm, sometimes hard but usually brief. Crucially, several regulars pointed out it's never oppressively hot here even in the rainy season, since the lake's highland elevation keeps temperatures moderate regardless of rainfall - a rain jacket was the standard packing tip rather than heat gear.

Forum posters describe a consistent daily pattern here in February: warm enough for short sleeves and shorts by day, cooling to genuine sweater weather once the sun goes down - a real day-to-night swing typical of this lake's elevation. February sits squarely in the dry season, with posters noting humidity stays low enough that air conditioning generally isn't needed. Rain isn't common this time of year but does occasionally happen, and posters mention an occasional cold front can push daytime temperatures down enough to want a sweater even before evening. Overall, posters consistently rate February among the more comfortable, predictable months for exploring Panajachel and the villages around Lake Atitlan.
