A score comparing how good piste is likely to be this week at Chapelco versus what Chapelco normally delivers in early July, 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.
The best week for snow at Chapelco is the week of 28 September (score 3/5) with low crowds.
Bluebird overhead with fresh snow on the corduroy. Top-drawer conditions. Extreme wind. Lifts likely closed.
Ski of the day: Wide all-mountain or a proper freeride ski. Deep snow base and a bluebird day. Get off-piste early and hunt the untracked bits before the crowd finds them.
The air here is 87% cleaner than the average comparison city right now.
Significantly cleaner air than a typical city. Ideal for outdoor exercise with minimal respiratory strain.
Not a pollutant. Ozone is naturally higher at altitude and near the coast, and lower in cities where traffic exhaust breaks it down. High readings here typically indicate clean air. Can cause short-term airway irritation during intense exercise but is not linked to the long-term health risks of particulate pollution.
Additive health score: each pollutant contributes points relative to its WHO 2021 guideline and long-term health impact (PM2.5 9, NO₂ 5, O₃ 3, PM10 2, SO₂ 1 at WHO limits). Data via Open-Meteo. City markers show live readings. Red line marks the WHO guideline. Updated 22:45

View Best Time to Go →Combining historical conditions with school holiday crowd pressure to find the sweet spot.
The timing score combines two signals: historical conditions quality (how good the skiing or surfing typically is in a given week, based on 5 years of weather data) and crowd pressure (how many of this destination's feeder markets have school holidays that week).
Crowd pressure is weighted by each feeder country's share of visitors. If 40% of a resort's visitors come from France and France is on holiday, that contributes 0.40 to the crowd pressure score. Crowds can reduce the timing score by up to 35%, ensuring conditions still matter most.
Scores: 5 = great conditions with low crowds (the sweet spot). 4 = great conditions with moderate crowds, or good conditions with low crowds. 3 = average. 2 = below average conditions or very crowded. 1 = poor conditions or peak holiday chaos.
