Wetter in San Salvador de Jujuy im September

Tilcara-forum threads comparing towns across the Quebrada de Humahuaca describe this as the more developed base of the three, better infrastructure and more dining options than smaller Purmamarca while still working well as a hub for exploring the wider valley. Posters call September through the following few months a genuinely favorable stretch, daytime temperatures comfortable though the roughly 2,400 meter elevation means a dramatic drop once the sun starts going down. Regulars describe evenings as turning noticeably cool fast, layering standing advice, a fleece and windproof shell recommended over the daytime t-shirt. Posters call the air here genuinely thin and clear this time of year, a real factor for anyone unused to altitude. Regulars recommend the colorful Cerro de los Siete Colores and the market as worthwhile stops regardless of exact dates. The record: 21.8C days feeling like 20C, 9C nights, a low 52 percent humidity and 10.8 hours of sun.

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.
