Climate Characteristics of Salta
General Overview
Salta enjoys a subtropical highland climate. Due to its elevation, the weather is much milder and more temperate than the lower, hotter regions of northern Argentina. The city is characterized by a very long dry season (winter and spring) and a short, concentrated rainy season (summer).
Summer and Rainy Season (December to March)
Summer in Salta is warm and rainy. Daytime temperatures range between 26°C and 28°C (79-82°F), and humidity is relatively high. Most of the annual rainfall occurs during this period, usually as intense afternoon or evening thunderstorms, which turn the surrounding mountains a vivid green.
Winter and Dry Season (June to August)
Winter is the driest and clearest season, considered an excellent time to visit. Days are sunny and pleasant (around 19°C to 21°C / 66-70°F), but due to the high altitude and lack of cloud cover, nighttime temperatures drop significantly and can reach 3°C (37°F) or less. Snow is an extremely rare event in the city itself.
Transition Seasons and Special Phenomena
Spring (September-November) is the warmest and driest period of the year before the rains arrive, with temperatures sometimes climbing above 30°C (86°F). Autumn (April-May) offers stable and very comfortable weather for walking tours in the city and its desert surroundings.
