Pacifica Weather: Extremes since November 2001 (partial)

Pacificaweather.com recordkeeping began on November 1, 2001. However, as a personal weather station, there are significant gaps in the historical data. Of over 150 months of elapsed time, 13 months are missing, or about 8%; in particular, data is missing from June-August 2005, July 2008, and February-September of 2009. The remaining 92% of records are present, but, being a personal weather station, instrument inaccuracy and data errors could be present in some of this data as well. To cross-check nearby weather data for a record or a specific date, consult the official NWS weather records for San Francisco at http://www.nws.noaa.gov/climate/xmacis.php?wfo=mtr.
