What does the RideWindow ride score measure?
It is a 0–100 score for one hour at one place, built from temperature, rain, wind, visibility, road grip and daylight. Near-freezing temperatures after rain, visibility under 200 m and gusts over 90 km/h force it to 0 (No-Go), and reduced grip caps it. It is a weather opinion, not a safety guarantee.
Why the weather matters on Col de l'Iseran
Col de l'Iseran: one of the highest paved passes in the Alps, linking Val d'Isère and the Maurienne. The open summit is exposed to wind, and the season is short.
The score is for the summit (2,764 m), usually the coldest and most exposed point of the ride; the valleys on either side are often warmer and drier. The score is weather only: it does not know whether the road is open. This road closes in winter, so check its status before you set off.
The score is not a comfort number. It prices the things that actually stop a ride: freezing rain with wet roads, visibility under 0.2 km, and gusts over 90 km/h all veto the hour outright, and the grip estimate caps a greasy-road hour even when the rest reads as a recommendation.
What the live forecast adds
- A 0–100 ride score for every hour over the next seven days, with the points behind it.
