- Closed: autumn through spring (snow/ice likely).

☝️ Even when the road is open, weather at altitude can suddenly change — afternoon storms, cool temps, or wet conditions are common in the Alps.
☀️ Typical Weather & Conditions (Cyclist‑Relevant)
While there’s no live forecast available for the pass specifically right now, here’s what seasonal and regional climate data suggests:
🌤 Summer (Jun–Sep)
- Warm in valleys, cooler near summit.
- Typical summit temps can be 10–18 °C even in summer.
- Afternoon thunderstorms are possible — common in Alpine weather.
🌦 Transitional Seasons
- Late May / early June: still cool at higher altitudes, possible snow patches in early season.
- September: pleasant riding window but watch for early snow/closed passes at higher elevations later in month.
🌀 Wind and Precipitation
Nearby lower‑elevation data suggests moderate winds and a mix of rain/sun through transitional months — not precise for the summit, but consistent with typical alpine variability.
🚴♂️ Key Tips for Cyclists
Before you go:
- Confirm current road status via local transport or tourism sites just before your ride — opening dates can shift due to snow melt and safety checks.
- Dress in layers: summit temperatures can be cool even in summer.
- Start early: afternoons often see more clouds/storms in the Alps.
- Be prepared for rapid weather changes — good rain gear and wind protection help on descents.
Road quality:
The pass is fully paved and widely ridden by cyclists, but watch for debris or wet patches after rain, especially late spring/early summer.
