How often is this page updated?
Each location is refreshed every three hours. The 7-day forecast, luck factor and packing notes are computed from the same stored update.
What is the luck factor?
A score comparing how good piste is likely to be this week at Cerro Castor with the version-matched historical observations available for early October.
Where does the data come from?
Open-Meteo weather for every resort, including temperature and humidity through the atmosphere, sun on each slope and wind. Official run reports, snow stations, satellite snow cover and skier check-ins correct the snow model where they exist, and runs and lifts come from OpenStreetMap via OpenSkiMap. The Piste board lists every source and licence under How the score works.
Does a high score mean the piste is good right now?
It means the snow and weather add up to good skiing for an experienced skier on the terrain that is open. Limited open terrain already lowers the score, a closed resort or run shows Closed instead of a number, and the likely range shows how sure we are. Check the resort's own report and webcams before committing.
When is the best time for Piste at Cerro Castor?
The best week for snow at Cerro Castor is the week of 12 October (score 3/5) with low crowds.
