San Diego Rainfall - by Year and Season

San Diego Rain History

As a San Diego resident I've found it hard to find a convenient place to find annual rainfall data for San Diego in a useful format. Most records are kept by calendar year, but San Diego's weather is highly seasonal with most of the rain falling in the November-March time period. I have developed a file of monthly rainfall data which presents the data by both calendar year AND by season (running from July to Jun).

The following file is comma delimited, in the format of:

Year, Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec, YearTotal, NextJan, NextFeb, NextMar, NextApr, NextMay, NextJun, SeasonTotal

File is here (sandiegorain.txt). It is current through Feb 2005. It is easy to bring the data into a spreadsheet. Create an empty text file; select all of the data from the "sandiegorain.txt" page; paste it into the empty text file and save the text file. Then open a spreadsheet program and import the data from the saved text file. If anyone wants me to update this file Contact me and I will do so if there is sufficient interest - so little time and so many other things to do!

The data was derived from NWS records going back to 1850, the link I use to have here no longer works. Some of the totals in early years may result from incomplete data.

If you are looking for official NWS statistics for recent days, see go to http://newweb.wrh.noaa.gov/climate/index.php?wfo=sgx. This is updated everyday by the NWS and is where I go to get update info.

March 21, 2005 evening note: I've made two small corrections to the sandiegorain.txt file. November 2004 was .33" not .34", December was 4.01", not 4.10".
