How often is this page updated?
Current conditions refresh every 3 hours when the cron runs. The 7-day forecast, luck factor, and packing notes are all pre-computed at the same time.
What is the luck factor?
A score comparing how good skiing is likely to be this week at Keystone versus what Keystone normally delivers in mid-May, based on the last 5 years of weather data.
Where does the data come from?
Open-Meteo, a free open weather API that blends multiple national weather services plus an archive going back decades. The same data powers many outdoor apps.
Does a high score mean the skiing is good right now?
It means the weather data suggests good conditions. Local factors like lift closures, off-piste avalanche risk and grooming still matter. Check resort webcams and the local piste report before committing.
