Best time to cycle Switzerland
Late June to late September, once the high passes clear. August offers the most reliable run of open passes and settled afternoons; September brings colder mornings and emptier roads.
Month by month
- October – MayPasses closed
- Snow keeps the high roads shut; valley routes only.
- JuneOpening
- Passes clear through the month, with meltwater and snow banks at the top.
- July – AugustBest
- All passes open, meadows in flower, thunderstorms confined to late afternoon.
- SeptemberVery good
- Cold starts, crystal air, far fewer vehicles on the pass roads.
Daylight
Around fifteen hours in August. Climb early — afternoon build-ups are the usual pattern, not all-day rain.
Wind
Valley breezes rather than weather systems: upvalley in the afternoon, downvalley overnight.
Roads and surfaces
Immaculate sealed pass roads; a few gravel service tracks avoid the tunnels.
