Nights can be freezing even in May. Bring layered clothing and check snowfall or thaw conditions. Summer (July – August) Best cycling conditions: warm valleys, cool at altitude. Be prepared for rainstorms and thunderstorms , typical in the Alps. Snow on road surfaces is possible after cold fronts but usually melts quickly. Autumn (September – October) Weather becomes less predictable — temperature can quickly drop with early snow. Roads may still be open early in autumn, but watch forecast closely. Winter (November – April) Pass is closed to vehicles and usually impassable . Snow keeps road inaccessible and unsafe for cycling. 🧭 Weather Tips for Cyclists Check local webcams/weather reports before departure — summit conditions can differ greatly from the forecast at lower altitudes. Dress in layers: Windproof and warm gear is essential at altitude. Brakes & tires: Roads can be wet or icy early or late season; choose tread and brake setup accordingly. Plan daylight hours: Weather changes quickly and descents can be cold at sunset. Gear for rain/hail: Alpine storms are frequent. Emergency fallback: If weather turns bad, consider shorter routes or transfers via train/tunnels where possible.
