Thời tiết Mussoori vào tháng 12

Rishikesh's forum calls December cool and dry, with fog a real factor in the mornings and evenings by the second half of the month — pack real layers, regulars say, not just a light jacket. White-water rafting stays open through December, just past the July-through-September monsoon closure.

Forum posters consistently describe October in Mussoorie as pleasant by day and mildly cold at night, with the first week specifically noted as comfortable during daytime but genuinely cold in the early morning and evening - posters consistently recommend good woolen clothing for these cooler hours regardless of the pleasant midday temperatures. Posters are direct that late October brings no real concern about monsoon rain or flooding, unlike earlier in the rainy season. Posters flag snowfall as reserved for January and February, not October, so visitors shouldn't expect any snow this time of year despite the chilly nights. Posters generally rate October as one of the better months to visit Mussoorie, with easy sightseeing conditions and manageable temperatures throughout the day.

April is peak season in Mussoorie — the forum calls late March and April ideal, and busy with it — because the hill station is the escape from a plains April that is already punishing. Figures vary a lot depending on who is quoting them: posters commonly give 30°C days and 18–22°C nights, while the monthly record for the hill station is cooler, nearer 22°C and 8°C. That is the sort of gap you get between a ridge town and the valley below it, and it is worth knowing both numbers exist. Either way, an evening at 2,000m wants a proper layer in a month India thinks of as hot. Rain is not negligible either, around twelve days. Regulars are candid that hill weather is unpredictable — mostly sunny and pleasant, but not something to rely on.
