When to Go in California

Edit This

California is a long state, so the climate varies from location to location. The most noticeable differences in weather are between the north and south of the state.

Working up from the south to the north, the four largest cities of California are the popular tourist destinations of San Diego, Los Angeles, San Jose, and San Francisco.

San Diego

San Diego is very southerly in the state of California, and its climate is usually described as being “Arid Mediterranean.”

San Diego temperatures are consistently warm throughout the year. Temperatures average the lowest between December and March, when it is usually 55˚F and 60˚F. These months also average the most rainfall, particularly in January and March. However, there are generally few days of rain throughout the year.

It is hottest from July through September, with temperatures usually in the low 70s. These three months also experience the fewest days of rain.

It is also worth remembering that many cruises on the Pacific Ocean leave from San Diego, so when planning a trip it may be beneficial to check the weather and accessibility of some nearby areas of interest.

Los Angeles

It is warmest in Los Angeles May through October. Temperatures begin to turn noticeably cooler in December, and although the winter is mild, the months of January, February, and March experience both cool temperatures and noticeable rainfall.

Los Angeles also suffers from the California phenomenon of “May Grey” and “June Gloom.” Thus, during late spring and early summer, the sky is often overcast or foggy, at least until midday.

San Jose

Although temperatures are considered to be generally moderate, they can vary. On average, the winter months usually experience temperatures in the 60s, but temperatures sometimes fall into the 40s, but with record highs in the low 80s.

From April to October temperatures average in the 70s and 80s, but can dip to the 50s and rise to be over 100˚F.

There are few days of rain or fog, and snow does not usually last on the ground. However, overnight freezes do occur in January.

San Francisco

San Francisco experiences four mild seasons. There is noticeable rainfall between the months of November through March, and the city is noted for often being clouded in fog.

Situated in Northern California, San Francisco is cooler than its southern sister cities, but it remains generally warm. From May to October temperatures are usually between 50˚ and 70˚F, and from November to April temperatures average between 40˚F and 65˚F.
