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).

NOTE: The Almanac conducted a recent audit of rainfall data collected for this specific station. This resulted in a number of revisions in this table.
