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).

Established in 1949, Pierce College Weather Station in Woodland Hills is one of the oldest unmoved operational cooperative weather stations in the world and one of the first official cooperative weather stations in the United States to independently provide its archived data online. In late March 2020, as California began closing down to deal with the COVID-19 pandemic, the station temporarily discontinued posting online data, while redoing and updating its data pages, making their weather reporting unavailable for a number of months. The station resumed posting weather data online later that year.
