California in May

California's weather stays pleasant year-round, but timing affects crowds and costs dramatically. April through June offers perfect conditions—warm days, cool evenings, and fewer tourists than summer. Hotel prices drop 30% compared to peak season. September and October bring California's true summer. Coastal fog clears, temperatures peak in the 70s-80s, and harvest season makes wine country magical. But everyone knows this secret—expect crowds and premium pricing. Winter (December-March) surprises visitors with mild 60-degree days along the coast. San Francisco stays cool and rainy, but LA enjoys perfect beach weather. Ski resorts around Lake Tahoe get serious snow, making this peak season for mountain towns. Summer brings the worst crowds and highest prices, especially July-August. Beaches pack with families, Disneyland lines stretch for hours, and hotel rates double. But if you're traveling with kids, summer vacation timing might force your hand. Avoid major holiday weekends unless you enjoy traffic jams and inflated prices. Memorial Day, July 4th, and Labor Day turn Highway 1 into a parking lot. Presidents Day weekend brings ski crowds to Tahoe—book accommodations months ahead. Microseasons matter too. June brings "June Gloom" marine layer to beaches, while September's Santa Ana winds create fire danger but gorgeous clear skies.
