Webcam footage from around the Matterhorn at the end of September reveals an almost bare mountain, with snow remnants clinging only to the highest elevations and sun-protected spots. High temperatures and a lack of significant snowfall drive this current state, following long periods of very warm weather in Switzerland that began in the spring and reached the highest parts of the Alps.
Why Warm Temperatures Strip Alpine Snow Cover
The zero-degree isotherm—the elevation where air temperature drops to freezing—climbed very high during warm episodes. Under these conditions, high-altitude snow melts quickly, preventing any new snow cover from lasting. The steep rock faces of the Matterhorn also struggle to hold snow compared to flatter terrain, leading to rapid exposure after dry spells. Yet, the current extent of bare rock in late September remains unusual.
Long-Term Climate Warming Across the Alps
Experts view this condition as part of long-term alpine warming. “This situation is not normal, but it is also not any catastrophe,” stated professor emeritus of geography Werner Bätzing. “It is a manifestation of current climate warming, which has been accelerating for about 15 years.” Bätzing added that climate warming brings more frequent natural disasters, citing rockfalls on the Matterhorn that made climbing difficult and prompted temporary summer closures.

Pro Tips for Alpine Safety
Mountain conditions can shift rapidly with elevation and weather patterns.
Outlook for Early October Weather Patterns
A significant snowfall could alter the appearance of the Matterhorn within hours or days. Mild snow is expected on some of the highest alpine peaks at the turn of September and October. However, a major snow accumulation is not yet anticipated, and warmer, drier weather is projected to return. This means the unusual view of bare Matterhorn rock faces may persist through the first days of October.
Frequently Asked Questions About Matterhorn Snow Conditions
Why is the Matterhorn lacking snow in late September?
Extended periods of high temperatures since the spring, a high zero-degree isotherm, and a lack of significant snowfall have left the mountain largely bare.
How does climate warming affect climbing on the Matterhorn?
Accelerated warming causes rockfalls, which can create hazardous climbing conditions and lead to temporary route closures, according to Werner Bätzing.
Will upcoming weather restore the snow cover?
Mild snow is forecast for the highest alpine peaks around the transition from September to October, but a major snow accumulation is not expected immediately.
