Austria belongs to the central European transitional climatic zone; climate is crucially influenced by the Alps, which are situated in a transitional area of the Mediterranean, the Atlantic Ocean and continental Europe. Austria can be divided into three climatic zones: The eastern part shows a continental Pannonian climate (mean temperature for July usually above 19°C, annual rainfall often less than 800 mm), while the central Alpine region has the characteristic features of the Alpine Climate (high precipitation, short summers, long winters). The remaining part of the country belongs to the transitional central European climatic zone, which is characterized by a wet and temperate climate. As Austria is a country with a highly structured relief, a lot of small-scale climatic processes occur caused by orographic conditions.

- In alpine regions temperatures can become considerably lower, mean daily temperature in January is -7.5°C (July: 13.2°C).
- Annual precipitation 700–2000 mm, depending on location, exposure and altitude.
- Glacier inventories show losses in area, volume, and duration of snow cover has been reduced in the last decades. Changes of precipitation have been observed.
