Traveller notes on Salta in April
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.
Other months in Salta
Forum posters describe October as warm by day - some reporting highs over 90F - cooling noticeably at night, with sunny skies and little rain the norm; posters note the broader April-through-November stretch here is essentially dry, so October sits comfortably within that reliable dry season. Standard packing advice given the day-to-night swing: layers for cooling evenings plus sun protection (sunscreen, sunglasses) for the strong high-altitude daytime sun. Posters consistently pair a Salta visit with nearby Cafayate (wine country) and Purmamarca (the colorful hillside town), both commonly reachable as day trips or short add-ons and similarly favorable weather-wise in October.
