South Lake Tahoe sees a fairly distinct division between the wet and dry seasons. The bulk of the precipitation occurs from late autumn to early spring, while the summer months are characterized by predominantly dry and sunny weather.

The highest amount of precipitation falls from November to March. March stands out as the wettest month, with an average precipitation of 6 mm and about 15 days of precipitation. January and December also receive significant moisture (5 mm each) and have around 11–12 wet days, respectively. Given that average temperatures in these winter months hover around or below freezing (for example, in January the average is 0.2°C with a minimum of -3.7°C; in February -0.6°C and -5.1°C), much of this falls as snow. Snowfall is common from December to March and can occasionally occur in November or April.

The summer period, from June to September, is the driest. July is the absolute driest month, with almost no rainfall (0 mm) and an average of only 3 days with any precipitation. June, August, and September are also very dry, with precipitation around 1 mm and 5–6 wet days per month. If precipitation does occur in summer, it is typically in the form of short-lived showers. October is a transitional month with a small amount of rain (1 mm) and only 4 wet days, signaling the start of the wetter season.

When planning a trip to South Lake Tahoe, it's important to account for changeable mountain weather. The key to staying comfortable year-round is layering your clothes. Temperatures can shift significantly throughout the day, especially with the elevation change. Regardless of the season, be sure to pack comfortable walking shoes, sunscreen (the mountain sun is strong even in winter due to reflection off snow or water), and sunglasses. A small backpack is handy for storing extra layers, water, and other essentials.

During the summer months (June–August) and early autumn (September), days in South Lake Tahoe are typically warm, with average temperatures between 15°C and 20°C and highs reaching 27–28°C. Pack light clothing: t-shirts, shorts, and thin trousers. However, evenings can be cool, so don't forget a light jacket, fleece, or sweater. You'll want a swimsuit for relaxing by the lake. Precipitation is minimal during this period, so heavy rain gear is unlikely to be needed, though a light windbreaker can be useful. A hat and sunscreen are must-haves.

In winter (December–March), as well as late autumn (November) and early spring (April–May), the weather becomes significantly colder. Average temperatures hover around 0°C, often dropping below freezing, especially at night. You will need warm, waterproof, and windproof outerwear, thermal base layers, and warm sweaters or fleeces. A hat, gloves or mittens, and a scarf are essential. Choose waterproof winter boots with good tread. While the total precipitation in millimeters is low, the number of days with precipitation (snow or sleet) in winter and March is quite high (11–15 days), so moisture protection is vital.
