⛰️ Col de la Bonette — yearly weather & cycling conditions guide
🗓️ Typical opening / closing period
  • The pass is closed in winter due to snow and only reopens after clearing operations. 
  • It is generally open May–June → October, depending on snowpack. 
  • Many sources note a practical window of mid-June to mid-October in average years. 
  • Some seasons it opens earlier (early May) or later if winter is heavy. 
  • Closure can also occur suddenly due to landslides or storms. 
👉 Example seasonal listing (2026 forecast) shows Restefond-La Bonette closed with provisional opening ~7 June, illustrating variability. 
🌦️ Seasonal conditions cyclists should expect
❄️ Winter (Nov–Apr)
  • Road closed; average ~2 m of snow accumulates. 
  • Avalanche risk, ice, and no snow clearing beyond winter sports access zones.
  • Even approaches may require winter tyres or chains for vehicles. 
Cycling: not feasible except ski-mountaineering style touring.
🌱 Spring (May–mid-Jun)
  • Opening period depends entirely on snow melt. 
  • Early season riding often features high snow walls along the road
  • Rapid weather swings: sun → sleet → wind in hours.
Cycling tip: bring winter gloves + rain shell even if valley temps feel warm.
☀️ Summer (mid-Jun–Aug)
  • Peak riding season.
  • Still naturally cool at altitude even when valleys are hot. 
  • Weather can change suddenly and temperature drops sharply after sunset
  • Strong winds common above 2500 m.
Cycling tip: UV exposure is intense due to altitude — sunscreen + hydration essential. 
🍂 Autumn (Sep–Oct)
  • Stable weather early in season but colder mornings.
  • Landscape turns golden; visibility often excellent. 
  • Increasing risk of early snowstorms → sudden closure.
Cycling tip: mornings can be near freezing even if afternoons are mild.
🌡️ General climate characteristics (important for riders)
  • Altitude of pass road ≈ 2800 m → temperature ~15–20 °C colder than valleys (standard lapse rate principle).
  • Thin air → reduced oxygen → noticeable effort increase.
  • Wind exposure above treeline with zero shelter for final kilometers.
  • No services near summit (last facilities far below). 
🚴 Short cyclist summary
Ride window: mid-June → late September is safest.
Best month: July or early September.
Main risks: sudden storms, cold descents, strong winds, late snow.
Rule: treat it like high-mountain terrain — even in summer carry layers + food + lights.
