Bise

Bise refers to a type of wind found in the Alpine regions, particularly prevalent in France and Switzerland. It is characterized by its cold, dry, and often northerly or northeasterly origin. This wind typically blows down from the mountains after periods of clear skies and cold nights. Bise is most common during the autumn and winter months, although it can occur in other seasons.

The arrival of the bise is often associated with a drop in temperature and a clear, bright sky. It can bring a refreshing change to the weather after periods of cloudiness or fog. While it can be a pleasant wind on a sunny winter day, it can also feel quite biting due to its low temperature and dry nature. The wind's strength can vary, but it is generally considered a moderate to strong wind.

The term "bise" itself is derived from the Latin word "boreal," meaning northern. This origin reflects the wind's typical direction and its cold characteristics. In some areas, the bise can also be associated with increased sunshine, as it often accompanies high-pressure systems that clear away moisture. Locals often use the bise as an indicator of impending colder weather.
