Väder i Guatemala City i januari

January in Antigua is the month the forum describes as about as good as the weather gets here: dry, sunny, highs in the 70s and 80s F, and rain perhaps once or twice across the whole of January and February. The catch is the night. Antigua sits high, temperatures drop into the 50s F after dark, and the colonial buildings have no central heating - so the cold is an indoor problem as much as an outdoor one. The packing advice regulars give is unusually specific: trousers and breathable short sleeves for the day, a fleece or light sweater for the evening, fleece preferred because it is warm, sheds light rain and does not wrinkle. The record: 25.5C days against 15.3C nights, 2.2 precipitation days carrying 6.8mm, humidity 67 percent, 10.4 hours of sun and AQI 67.

Forum posters describe June mornings in Guatemala as nearly always gorgeous, with rain typically arriving in the afternoon or evening - posters describe a reliable pattern where rain shows up predictably between roughly 4pm and 6pm rather than lasting all day. Posters consistently name June through October as the rainy season, but are direct that it seldom rains continuously, describing June specifically as still an enjoyable, manageable time to visit. Posters do flag that weather patterns have grown less predictable in recent years, with some visitors reporting an unexpectedly dry June and a genuine mix of cloudy and sunny stretches throughout the month. Posters generally rate June as workable with rain gear on hand, rather than a month that seriously disrupts travel plans.

Forum posters describe December as sitting within Guatemala's dry season, with rain, if any, described as far from the 'loads' some might expect from the wider region's reputation. Posters cite typical daytime temperatures in the low 70sF with nights dropping to the upper 50sF or occasionally into the 50s, genuinely chilly by local standards - posters are consistent that November through March can turn pretty cool in Guatemala City, Antigua and the highlands specifically. Posters flag real demand pressure around Christmas, with many Guatemalans traveling home to see family, driving up both flight prices and accommodation demand - booking hotels and travel well ahead for the final days of December is standard advice given how competitive that stretch gets.
