Temperatures were generally near normal throughout 2019. April and December were a little warmer than average, and February was cold. After several years of drought and extremely warm weather, this was a relief.
The big story was the rainfall. January, February, November and December were all significantly above average for rain. We ended up almost five inches above average for the year!
I've posted all the data below, along with month-by-month rain totals across San Diego County. I've also posted temperature and rain data for California and the entire United States.
