Rainfall, Precipitation, Weather, Map, Los Angeles County


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).

Pasadena
February 2023 Rainfall-to-Date

Daily data for this station is typically only reported in a single batch, approximately six to ten days after the end of the month. Occasionally, update reports during the month do come through, although not consistently or daily. We update here as these come through. Santa Fe Dam in Irwindale in the San Gabriel Valley is the closest weather station to Pasadena (just under 12 miles from Downtown Pasadena). It offers daily rainfall updates.
