Notes

[edit]
  1. ^ Mean monthly maxima and minima (i.e. the highest and lowest temperature readings during an entire month or year) calculated based on data at said location from 1991 to 2020.
  2. ^ Official precipitation records for San Diego were kept at the Weather Bureau Office in downtown from October 1850 to December 1859 at the Mission San Diego and from November 1871 to June 1939 and a variety of buildings at downtown, and at San Diego Int'l (Lindbergh Field) since July 1939.[1] Temperature records, however, only date from October 1874.
