Jackson Hole

Current conditions refresh every morning at 06:00 UTC from the daily snapshot. The 7-day forecast caches for 6 hours, and the historical baseline for this week of the year refreshes weekly.

A single 0-10 rating of how good skiing is likely to be this week at Jackson Hole. The biggest factors are current snow depth on the ground, how much fresh snow has fallen in the last 7 days, and what's in the 7-day forecast. We then add bonuses for bluebird powder mornings and knock points off for rain, warm spells, and high winds. The typical score next to it is what Jackson Hole usually delivers in mid-April, based on the last 5 years of weather data.

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.

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.

Open-Meteo may not have coverage for every metric at every location. Snow depth in particular is spotty outside major resorts. Everything else should populate within the first few daily snapshots.
