Weather
In summer, temperatures at the summit can range from -5 to 5 degrees Celsius. The weather is usually stable, but thunderstorms and fog can appear unexpectedly. Summer is the best time to climb Dufourspitze, but remember to prepare and equip yourself appropriately.
Winter on Dufourspitze means extremely difficult conditions. There is a lot of snow, a high risk of avalanches, and temperatures can drop to as low as -20 degrees Celsius. Winter climbing is only for very experienced mountaineers.
