Snow and opening dates 2026
Estimated recent snow, 7-day forecast, announced opening dates and official snow reports by resort.
The useful signal is not one huge combined total across the Andes, but three separate reads: how much snow fell recently, what may fall next, and what the resort's official report says once it is published.
Recent snow and forecast values are Open-Meteo estimates at each resort's summit elevation. Use them to compare mountain trends; before travelling, check the official report.
