In response to many many requests for how this rainfall season compares to previous wet years I have put together an archive of monthly rainfall for data for about 50 California locations. The data is cobbled together from a variety of NOAA and NWS sources. The data is for each location's entire period of record, but beware some locales have missing data. My plan is to update this at the end of the rainfall season (i.e., June 30). Please let me know of any comments, errate of suggestions. See http://ggweather.com/monthly/ . Enjoy.
