How Much Rain Did San Diego County Get in December? Here Are The Numbers

The short answer: More than average but still not enough

NBC Universal, Inc.

San Diego is used to 72 and sunny year-round but some much-needed rainfall came with several storm systems to sweep the region in December.

This month‘s rainfall totals are about twice above average for most areas this time of year, but even with December‘s heavy rain, San Diego County is still under our yearly rainfall average, according to local data pulled by NBC 7 Meteorologist Sheena Parveen.

In the mountains, we‘re still about a third away from our yearly average, if Palomar Mountain‘s data is any indication.
