The climate of Liechtenstein is continental at low altitude, while it's Alpine in the mountains. Liechtenstein is a small country, covering an area of 160 square kilometres (60 square miles), and located between Austria and Switzerland. The capital Vaduz is situated in the Rhine Valley, at 450 metres (1,450 ft) above sea level. The eastern part of the country is mountainous, and the highest peak is Grauspitz, 2,600 metres (8,500 ft) high.

In Vaduz and in the valley, the climate is continental, cold in winter, with a daily average temperature in January around freezing (0 °C or 32 °F), and relatively warm in summer, with a maximum average around 24/25 °C (75/76 °F) in July and August.
Here are the average temperatures of Vaduz.

In winter, from December to February, cloudy and dull days are frequent, accompanied with rain or snow, typically light but continuous. Sometimes, while in the valley the sky is overcast, in the high mountains the sun shines. On the other hand, outbreaks of polar air masses of Siberian origin can bring glacial weather, with temperatures below freezing even during the day.
During summer, from June to August, in periods of good weather there can be hot temperatures in the valley, which can be interrupted in the afternoon or evening by thunderstorms, sometimes intense.
The Föhn, the southern wind, warm and dry, coming down from the mountains, is more frequent in autumn, and can lead to sudden increases in temperature.
The average annual precipitation is around 950 millimetres (37.5 inches) in Vaduz, with a maximum in July, August and September, because of thunderstorms. In the other months of the year, the rains are quite frequent, brought by Atlantic fronts, but they are rarely abundant. In winter, precipitation often occurs in the form of snow.

In high mountains, where the climate is colder and windier, snowfalls can occur for a longer period, depending on altitude. In the mountains, even precipitation is more abundant and exceeds 2,000 mm (80 in) per year: the abundant winter snowfalls are replaced by the strong summer thunderstorms.



The sun in Liechtenstein is rarely seen from November to February, especially in the valley; in summer it shines a little more often, especially in the morning, while in the afternoon thunderclouds can develop even in good weather.
