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 touring is likely to be this week at Portillo 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 Touring board lists every source and licence under How the score works.
Does a high score mean the touring is good right now?
It means the best plan for the day, with its aspect and start time, should give an experienced ski tourer a good descent. It says nothing about avalanche danger, which never changes the score: read the local bulletin and make your own terrain decisions.
When is the best time for Touring at Portillo?
The best week for snow at Portillo is the week of 12 October (score 3/5) with low crowds.
