Spring
The cold and snow of winter often linger into April and May. In fact, March and April still average 36 inches and 15 inches of snowfall, respectively. Average temperatures during these months can range from a low of 22 degrees F to a high of 61 degrees F.
Summer
Summer-time temperatures in Tahoe remain relatively mild. During the day, expect average highs of around 70 to 79 degrees F. At night the temperature will often dip down into the low to mid 40s, so a light jacket is always a good idea. This time year is usually pretty dry, but scattered rain showers are possible.
Fall
Autumn weather can be pleasant in Tahoe, although temperatures average 10 to 20 degrees lower than summer readings--highs ranging from 40 degrees F to the upper 60s. Over-night temperatures can fall into the thirty and forties.
Snowstorms increase in frequency and intensity as winter approaches.
Sudden storms can cause a drop in temperature and/or result in precipitation.
Winter
Winter temperatures are cold, especially at higher elevations at the ski resorts. Expect average highs in the low 40s and average lows in the teens.
Tahoe will often receive in excess of 300 inches of snow, especially at higher elevations, so warm winter clothing is a must.
