Klosters, nestled in the Swiss mountains, features a typical Alpine climate with distinct seasons. The weather here is largely determined by altitude: winters are truly cold and snowy, while summers are fresh and moderately warm. This makes the resort attractive year-round, offering excellent conditions for both winter sports and summer hiking without the exhausting heat.

Winter months are characterized by steady frosts: the average temperature often stays below freezing, dropping to -11°C in January, which ensures a high-quality snow cover. Summer in Klosters is mild, with maximum temperatures around 17°C in July and August. You won't encounter tropical heat here, so a light jacket may be needed for evening walks even in the height of the season.

Travelers should take into account the high probability of precipitation throughout the year. The wettest period is late spring and early summer, especially May, when the number of rainy days reaches its peak. When planning a trip to Switzerland, be prepared for changeable weather and be sure to bring appropriate gear to stay comfortable in any conditions.

The climate in Klosters is distinctly Alpine, meaning frosty, snowy winters and refreshingly cool summers. The annual temperature range is quite wide: from harsh winter cold to comfortable summer warmth. The coldest time of year is traditionally January, when the average temperature drops to -7.0°C, and night frosts often reach -11.1°C. December is not far behind in severity, creating ideal conditions for the formation of a stable snow cover, which is highly valued by winter sports fans.

The summer season here is mild and pleasant, without exhausting heat, making the resort a wonderful place for those who prefer cooler temperatures. The warmest months are July and August, when the air warms up to an average of +17.2°C during the day. However, even in the height of summer, you should consider the mountain specifics: temperature fluctuations between day and night are quite noticeable. After a comfortable day, the temperature at night can drop to +7.4°C, so warm clothes will be needed even in July.

Transition seasons in the Swiss Alps are characterized by a gradual change in weather patterns. Spring arrives slowly in Klosters: in March, average figures still remain negative (-2.2°C), and it is only in April that positive temperatures become established. In autumn, after a relatively warm September with an average temperature of +8.2°C, the air cools down quickly, and by November, light frosts return, preparing the town for the start of the ski season.

In Klosters, the nature of precipitation is closely linked to the seasonal temperature changes typical of the Swiss Alps. The winter months, from November to March, are characterized by steady sub-zero temperatures, so precipitation here falls mainly as snow. This time is perfect for winter sports enthusiasts: in January and March, it can snow for about 15–16 days a month, creating a stable snow cover.

Spring and early summer bring an increase in the frequency of precipitation. May holds the record for the number of rainy days—rain can be observed for 25 days. In summer, especially in June and July, rain also occurs quite frequently (more than 20 days a month), but thanks to the positive temperatures, these are often refreshing showers followed by sunshine.

The least rainy (or snowy) period is February, when the minimum number of precipitation days is recorded—about 13—as well as mid-autumn. In October and November, the number of wet days decreases to 14. Overall, when heading to Klosters, you should be prepared for precipitation in any season: fluffy snow in winter and regular rain in summer.

When packing for a trip to Klosters, it's important to remember that this is an Alpine resort where the weather can be changeable and cool even during the warmer months. In winter, when temperatures consistently stay below freezing, the foundation of your wardrobe should be high-quality thermal layers, wool sweaters, and reliable outerwear—a down jacket or ski jacket. Be sure to bring a hat, scarf, warm gloves, and winter boots with thick, non-slip soles to stay comfortable on the snowy streets.

Summer here is mild and fresh: even in July and August, the average temperature rarely exceeds 17°C, so light T-shirts are best complemented by fleece sweaters, windbreakers, and long trousers. The principle of layering will be your best friend, allowing you to adapt quickly to temperature changes throughout the day. Given that May and June are the rainiest months, a waterproof jacket or a quality raincoat is a must-have in your luggage.

Regardless of the season, you'll need comfortable, broken-in, and preferably waterproof shoes for walks in the picturesque surroundings. Since rain or snow is possible year-round, a compact umbrella will also come in handy. Additionally, don't forget sunglasses and sunscreen with a high SPF, as the mountain sun can be very intense even in cloudy or cold weather.
