Detailed cycling weather forecast for Pas de la Graille. See wind direction, temperature and rain along the entire climb and descent.

• Pas de la Graille is a mountain pass at about 1 597 m elevation on the Montagne de Lure plateau in the southern French Alps. It’s reached via road D53 and connects valleys around Cruis and Valbelle/Forcalquier. 
• It’s a true cycling climb / road ascent that’s used by riders (including in routes like Montagne de Lure loops) and is quieter and more scenic than big Alpine cols. 

• The road over Pas de la Graille (D53) is accessible in the warmer months and typically closed in winter due to snow — this is mentioned in geographic context (roads are closed in winter on the Montagne de Lure). 
• While there isn’t an official mountain‑pass closure calendar like for very high Alpine cols (which often open mid‑May to mid‑June), you should assume late spring to early autumn (roughly ~April/May to October/November) is the season when it’s rideable — depending on snow and weather conditions that year.

• Being at ~1 600 m in southern France, weather is very variable and mountain‑like — even in summer you can encounter quick changes, thunderstorms, or cooler summit temps. 
• In spring (April–May): roads may still have snowpack early in the season and temperatures can be low at the pass. 
• Summer (June–August): generally the best cycling season; warm in valleys, cooler at altitude. But afternoons often bring thunderstorms — plan early starts. 
• Autumn (September–October): can be great riding weather, but temps drop and early snowfall/rain can make high roads tricky. 
• Winter (Nov–Mar): snow and closures make it unsuitable for road cycling at the pass.

❗ Important: Pas de la Graille isn’t as high as famous Alps passes (like Galibier), but as a mountain pass its road can be snow‑covered or closed in shoulder/early season months. Always verify local road status just before your ride with French traffic/road apps or local tourism offices.

• Start early in the day to avoid afternoon thunderstorms. 
• Bring layers (windbreaker/arm warmers), as temperatures at ~1 600 m will be significantly cooler than the surrounding plains. 
• Check a local weather forecast for Cruis/Valbelle area before heading up (mountain weather changes quickly).
