Climate chart - Lake Tahoe
The climate of Lake Tahoe is moderately continental, with cold, snowy winters and sunny summers, which are warm during the day, but with cool nights.
The lake is located north-east of San Francisco and Sacramento, on the border between California and Nevada, and 1,900 meters (6,200 ft) above sea level. A short distance away are the cities of Carson City and Reno, both in Nevada. Around the lake are several winter sports resorts, the largest of which are the Heavenly Mountain Resort in the south and the Squaw Valley Ski Resort in the northwest.
In winter, the night temperature normally drops below freezing, sometimes even by several degrees. On the coldest nights of the year, the temperature generally reaches -18/-20 °C (-4/0 °F), but sometimes it can even drop below. In February 1989, it dropped to -33 °C (27.5 °F) in South Lake Tahoe. Snowfalls are abundant: almost 5 meters (16 feet and a half) of snow fall in the northern part and almost 3 meters (10 ft) in the southern part of the lake. Usually, it snows from November to April.
In summer, there are strong differences in temperature between night and day, so it can be cold at night, while it is warm during the day. On the hottest days of the year, the temperature generally reaches 30/33 C (86/91 °F). In summer, water sports are practiced on the lake. On rare occasions, thunderstorms can break out in the afternoon.
