Meteo San Salvador de Jujuy in aprile

Salta's forum describes April as the tail end of the wet season, with roughly even odds of rain early in the month dropping off sharply as it goes on - several posters said the rains typically wrap up around Easter, after which the Northwest settles into some of its best weather of the year. Nights get properly cold at Salta's altitude even as days stay mild to warm. The practical advice repeated most often is to avoid driving the mountain routes toward Cachi during an active downpour, since those roads are more exposed than the well-paved routes to Purmamarca or Cafayate.

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.
