NOTE: When most weather reporting sources cite weather in Los Angeles (without specifying where, exactly, in Los Angeles), these numbers are typically for the Downtown Los Angeles weather station (actually located on the USC campus).


Rainfall and Raindrops
How Much Water is One Inch of Rain?


With a cumulative total of 53.59 inches of rainfall, thus far, for the last two rain seasons in Downtown L.A. (2022-2023 and 2023-2024), this is now the second wettest two consecutive rain seasons for Downtown since 1879. The wettest consecutive two seasons were between 1888 and 1890 with a combined 54.12 inches. This now ranks the last two seaons at just a little more than half an inch behind the wettest two consecutive years on record.



On May 20, 2024, at about 8 AM Pacific Daylight Time, the official Downtown Los Angeles weather observation site was relocated from the University of Southern California (USC) campus, where it had been located since 1999, to the Frank Hotchkin Memorial Training Center in Elysian Park. The new site is at the training center for the Los Angeles Fire Departmenton, on the south side of Dodger Stadium, approximately four miles northeast of the USC campus. The center was formerly known as the Navy and Marine Corps Reserve Center.

Nevertheless, the National Weather Service (NWS) continued reporting for the USC location through the end of May. Until NWS completes the changeover in reporting, the Almanac will continue to post here for both sites.
