The following is a graphical climatology of San Diego, California temperatures and precipitation, from 1875 through 2012. Included are summary overview charts followed by 138 year-to-year graphs depicting daily temperatures, temperature anomalies, and precipitation. The 1875 to 2012 period of record includes observations from eight different but relatively nearby Weather Service Office locations downtown (through 1926) and three at Lindbergh Field (1927-present). The latter is about 1.5 miles to the northwest of Downtown, and about 30 feet lower in elevation (~ 15 feet msl). For the pre-Lindbergh Field era, thermometer placements ranged from 20 ft to 94 ft above ground level, those at Lindbergh Field form 6 to 37 feet above groundlevel.
A small number of missing data, comprising 45 days, or ~.001 % of the record, were filled using observations from nearby Chula Vista.
Data were accessed from the Utah Climate Center and NCDC Online sites, plus that of the NWS-San Diego site.
