June weather forecast
California, USA

June marks the beginning of summer in California, characterized by a noticeable increase in temperatures and continued dry conditions. Coastal areas like San Francisco and Los Angeles see temperatures ranging from 65°F to 75°F. This increase in temperature compared to May signals the arrival of summer, though coastal regions often benefit from a moderating influence from the Pacific Ocean, preventing extreme heat.

In the Sierra Nevada mountains and other inland regions, June brings a further increase in temperatures, with averages between 40°F to 50°F. Snowfall is now almost completely absent, and the landscape is dominated by summer weather.

Eastern desert regions, including Death Valley, begin to experience the heat that is typical of California’s summers. While not yet at their peak, temperatures in these regions are significantly warmer than in May, setting the stage for the hot summer months ahead.

Rainfall in June is scarce, with many parts of the state receiving little to no precipitation. Any rainfall that does occur is likely to be confined to the northern regions, continuing the pattern from previous months. However, the decrease in rain is even more pronounced in June, making it one of the driest months of the year.

Comparing June to May, there is a clear transition from the mild and pleasant conditions of late spring to the warmer and drier climate of early summer. Temperatures increase across the state, coastal areas remain temperate, inland and mountainous regions warm significantly, and desert areas start to heat up. The continued reduction in rainfall and rise in temperatures set the stage for the hot, dry summer that California is known for.
