What’s the weather like in California in May?

The west coast state of California has a Mediterranean-style climate with long, hot summers and short, cool winters. May is springtime in California, and as the summer months draw near, temperatures are getting warmer while the chance of rain is very low. If you want to explore the state’s vibrant cities and beautiful beaches, this is a great month to visit.


In May, the city of Los Angeles has an average daytime temperature of 17°C, with highs of 22°C in the afternoons and lows of 12°C at night. Just 10mm of rain is forecast in LA this month, so there’s not much chance of it getting wet. Further north in San Francisco, temperatures are a few degrees cooler with highs of 17°C and lows of 10°C. The city’s also slightly wetter this month, but still relatively dry with just 20mm of rain expected in May. If you’re swimming in the sea, the Pacific is still a cool 16°C during this month.
