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: All measures are those officially reported by the National Weather Service (NWS), except where otherwise noted. Typically, NWS reports for this station may lag for up to several days, so recent measures (where noted) are provided by the UCLA Weather Station. These may be quite different from NWS reports, however. When we receive updated NWS data, we revise the table below accordingly.
