サルタ 5月の天気

Tilcara-forum trip reports describe the Quebrada de Humahuaca region as reliably pleasant even heading into the cooler months, posters calling the weather here genuinely good by comparison to the harsher conditions found elsewhere in the Andes at similar elevation. The narrow valley, lined by colorful high mountains with Route 9 running alongside the Rio Grande, is called striking regardless of exact travel dates within the favorable season. Tilcara itself is described as an attractive if somewhat dusty town on the valley's east side, a solid base for exploring both the town's own archaeological site and nearby Purmamarca. Posters call the temperature swing between day and night significant at this elevation, warm sun through the day giving way to a real chill once it sets, layers standing advice regardless of how the afternoon felt. The record: 19.8C days feeling like 18C, 8.8C nights, 50 percent humidity and 9.8 hours of sun.

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.

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.
