When researching what is the coldest month of the year in California – you might need to know a little more about the monthly averages too. These lists (below) of the average monthly temperatures in Californian locations is really useful as an overview of the different monthly temperatures and as a comparison of the month to month averages.

However, it’s hard to find an average comparison for the state as a whole – because the state is so big, and the climate does vary widely from location to location. For example, from the beaches to the mountains – you’ll see big differences in temperatures.

Because of this (and to provide the most useful information possible), I’ve pulled various data from 2 of the main cities in California. The data below is the average monthly temperatures using a 10-year average from 2010 to 2019 in both Los Angeles and San Francisco. So hopefully this information proves useful!
