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).
Reporting for this station is not reported at consistent intervals. Reports are never posted on a daily basis, but, may be reported in a single monthly batch, about six to ten days after the end of the month. In other months, update reports for Pasadena come through in batches once or twice during the month. We update here as soon as these updates come through. As an alternative, Claremont, at the eastern end of the San Gabriel Valley, may have the closest similar micro-climate as does Pasadena (about 24 miles from Downtown Pasadena). This station reports daily and hourly.
