What's the weather like in Salta by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Salta during Apr–Sep?
Excellent — warming up, dry, clear skies. September is the patron-saint festival (Milagro pilgrimage 13–15 September); October and November are the best months overall before the rainy season starts.
Shoulder season (Mar, Oct) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Feb, Nov–Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
What festivals and events happen in Salta?
- Milagro (Miracle of Christ and the Virgin)September 13–15
Salta's biggest religious festival — pilgrims walk from across NW Argentina to venerate the images of the Señor del Milagro and Virgen del Milagro that survived the 1692 earthquake. Up to a million pilgrims arrive over three days; hotels triple in price. The 14 September procession through the centre is the climax.
- Día de la Tradición10 November
Argentina's gaucho heritage day, celebrated more intensely in Salta than anywhere else (because of Salta's connection to Martín Miguel de Güemes and the Independence Wars) — gaucho parades on Plaza 9 de Julio, asados, folkloric music. Free.
- Cafayate Wine Harvest (Vendimia)Late February
The annual grape harvest in the Cafayate wine valley — wineries open to visitors, harvest dinners, and the crowning of a Vendimia Queen. Combine a 2-night Cafayate stay with this festival for the full experience.
- Salta Festival of Folklore Music (Pre-Cosquín)Late August / early September
The Salta selection rounds for the major Cosquín folklore festival in Córdoba — local folkloric musicians compete to advance, with concerts on Plaza 9 de Julio. Free for the open-air concerts.
- Carnaval SalteñoFebruary (week before Lent)
Salta's carnival — Andean-influenced (different from the European Carnival of Buenos Aires), with the use of harina (flour) and water bombs. Smaller and more local than the Brazilian or Bolivian carnivals; the Cafayate carnival is more exuberant.
