Het weer in San Salvador de Jujuy in maart

Tilcara-forum threads on the wider Jujuy region in March describe this as the tail end of the rainy season, posters calling wet days considerably fewer than the reputation suggests, roughly ten days with measurable rain across the month. Regulars call daytime temperatures mild and pleasant, the intense Andean sun still strong enough to warrant real sun protection despite the altitude keeping the air comfortable. Posters describe some visitors going stretches without a drop, others catching an afternoon downpour that clears within an hour. Regulars recommend layering for the swing between midday sun and evening chill. Posters call the colorful Quebrada de Humahuaca formations genuinely striking under March's clearer post-rain skies. Regulars recommend checking road conditions first, unpaved routes occasionally affected after a heavier system. The record: 21.2C days feeling like 22C, 12.4C nights, an extraordinarily high 324.7mm across nearly 27 days and 82 percent humidity.

Northwest Argentina's forum describes February as squarely in the rainy season for Jujuy and neighboring Salta - some roads can flood or become impassable, but mornings are typically clear with little landslide risk, and the big storms tend to arrive in the afternoon rather than at random. Posters recommended strong sun protection regardless, since the sun is intense whenever it does break through the cloud cover. It's a month that rewards flexible day planning - clear mornings for sightseeing, afternoon plans held loosely in case a storm rolls in.

Forum posters describe this stretch of northwestern Argentina in August as genuinely excellent - close to zero chance of rain, a dry climate, and sunshine essentially every day, though cold mornings and nights are a real feature of the season. Posters describe a typical day warming into the high-60s to low-70sF by early afternoon before dropping sharply once the sun starts setting, commonly down into the 50sF or cooler by early evening. Posters recommend light clothing plus a hat and sunblock for midday sun exposure, alongside a fleece for the cold mornings and evenings - the day-to-night swing here is described as the defining feature of the season rather than any single extreme.
