August weather forecast

August continues the summer trend in California with warm temperatures and dry conditions, but subtle changes begin to emerge as the state approaches the end of the summer season.

Desert regions, such as Death Valley, remain hot but may begin to experience a slight drop in temperatures. Although still above 100°F (37.8°C), the extreme highs of July start to recede. However, August remains one of the hottest months in these areas.

Rainfall continues to be rare in August, and the state remains predominantly dry. The pattern of minimal precipitation in the northern regions persists, but overall, rain is scarce.

Comparing August to July, there is a continuation of summer weather, with only subtle signs of the impending transition to autumn. Coastal areas remain temperate, while inland and desert regions may begin to see a slight decrease in temperatures. The state's varied topography and proximity to the Pacific Ocean create a complex weather pattern in August, with warm but not excessively hot conditions in most areas and only slight variations from the weather in July. The gradual shift towards cooler temperatures in some parts of the state hints at the end of summer and the approaching change in seasons.
