Detailed cycling weather forecast for Col du Banchet. See wind direction, temperature and rain along the entire climb and descent.

• Col du Banchet is a lower, Jura-region mountain pass at about 590 m elevation in Savoie, France (between the valleys of Guiers and Lac d’Aiguebelette). 
• It’s a relatively small climb suitable for cycling and mostly free of seasonal closures due to its low altitude. 

• Because it’s under ~600 m, Col du Banchet is generally open year-round for cyclists and vehicles — it usually doesn’t have winter closures like higher Alpine passes. 
• Winter snow or ice can still make it slippery in the coldest months, so caution is advised, but roads normally remain passable.

• Lower altitude means milder temperatures than high Alpine passes. Winter mornings can be around freezing and sporadic snow or ice possible.
• Spring and autumn bring variable conditions, including wet or cold days.

• Because it’s lower and not as exposed as high mountain passes, Col du Banchet is a good choice outside high-summer for quieter rides with less extreme weather.

These passes are often associated by cyclists with the “Mont-Cenis” area — they give context for changing conditions when you go higher than Col du Banchet.

• Closed in winter from roughly November and usually reopens in May (often 2nd Friday of May, e.g., 8 May 2026) depending on snow removal. 
• Snow and late storms can delay opening, and early closure in autumn can come from the first heavy snowfalls.

• Late May–September: Best time for cycling.
• July–August: Warmest, most stable weather, but thunderstorms can develop in the afternoons. 
• Shoulder seasons (May & October): Snow at summit, snow walls on sides even into summer; temperatures are cooler and unpredictable. 

• Temperatures drop quickly with altitude — at ~2 000 m summit: even mid-summer mornings can be brisk (single digits °C). 
• Afternoon thunderstorms are common in summer. 

• Generally open mid-June to late September (e.g., 15 Jun – 30 Sep) subject to snow conditions. 
• The narrow road does not receive heavy winter maintenance and is usually closed outside summer.

• Similar to Col du Mont-Cenis: summer months are best, but snow and cold can still linger early or late in the season above ~2000 m. 

• Winter (Dec–Mar): Very cold, snow, passes closed. 
• Spring (Apr–May): Snow melts gradually; low passes may open early, high passes later. 
• Summer (Jun–Aug): Warm weather, best window — but thunderstorm risk mid-afternoon. 
• Autumn (Sep–Oct): Cooler, passes start closing again; earlier snow possible. 

• Below 1500 m: Usually open and rideable mid-spring to late autumn. 
• ≈1500–2500 m: Open late May to October. 
• Above 2500 m: Open typically June to mid-October (more snow risk). 

• Col du Banchet (~590 m): low Alpine pass; generally open year-round; winter may bring snow/ice but no systematic closures. 
• High Alpine passes (Mont-Cenis & Petit Mont-Cenis): closed in winter; usually open from late May/June to September/October depending on snow/weather. 
• Weather for cyclists: stable summer months are best; early/late in season and afternoons can be unpredictable with cold or storms. 
• For high passes, always check exact opening dates and current conditions before planning your ride.
