Chasseral is a clarity location. On an ordinary evening it is a pleasant ridge; after a cold front or a Föhn clearance the whole Alpine chain appears at once, from Säntis across the Bernese Alps to Mont Blanc. That difference is entirely about air, which is what makes it worth checking a forecast before driving up.
Simplified forecast from the open model run. The full forecast — a second model, your exact viewpoint, the hourly cloud timeline — is in the app.
Sky colors
Why: The sun's path is clear at the height its low light travels, so the light can reach the clouds at sunset.
Terrain is drawn for illustration only — it is not used to calculate underlight or obstruction.

Spring to autumn while the summit road is open. Winter rewards the walk in when visibility is exceptional.
100–400 mm to compress the Alpine chain; 24–70 mm when the Jura meadows give you a foreground
Decide early whether the subject is the distant chain or the ridge you are standing on — they need different lenses and different spots.
45 minutes before sunset if you drive up; add the full route time in winter.
Drive to the summit in season. In winter the road closes and you take the marked hiking or snowshoe route.
Parking: Summit parking when the road is open; valley parking at the winter trailhead
Approach: Short walk from summit parking, or a marked winter route
