The answer to “when does it snow in lake tahoe” can be a bit complicated as every water year is vastly different. However, there are certain traits that can be expected. First, Tahoe’s winter is usually personified by a “feast or famine” storm cycle. That means that you will get a few storms that provide FEET of snow followed by a 4-6 week pause mid-winter nicknamed Juneuary (which is not fun for skiers).
The peak season for skiing in Tahoe happens between December and February, so if you are planning to come during those months, expect to find crowds at the resorts. This is because the locals from San Francisco and Sacramento flock to the area as soon as there is a significant snowfall, so you will have to book well in advance for lodging.
January is the snowiest month of the year, but even then, it doesn’t typically snow for the entire month. The weather in January is also quite cold, with average temperatures in the 40’s degF.
In February, the snow continues to fall and temperatures remain cold. It is a great month for skiing, as the slopes are covered with deep powder and the snow is soft and easy to carve through. It is also a very romantic time to be in Tahoe, as Valentine’s Day occurs in February.
