Zermatt, nestled at the foot of the Matterhorn, experiences a transition in climate during September. Typically, days are mild and sunny, offering ideal conditions for hiking and other outdoor pursuits. However, evenings and nights grow noticeably cooler, often requiring warmer clothing. The shift from summer to autumn brings crisp air and the first signs of fall foliage in the surrounding valleys.
Pleasant daytime temperatures combined with fewer crowds compared to the peak summer months make September an attractive time to visit. This period provides a balance between comfortable weather for exploring the region’s natural beauty and a quieter atmosphere. Historically, September marked the end of the main summer tourist season and the beginning of preparations for the winter months. This transition period often provided locals with a brief respite before the onset of colder weather and the arrival of winter tourism.
