2012-13 rainfall year is an unusual one in Menlo Park

by Bill Russ on June 30, 2013

Today ends the 2012-13 rainfall year, which began on July 1, 2012. The total number of inches of rain recorded in my backyard is 16.5″. That compares to 11.95″ in the 2011-2012 year and 20.8″ in the 2010-11 year.

What was surprising about the 16.5″ was that 14.65″ fell prior to January 1st and only 1.85″ the six months since. We have to hope much  of the early fall was captured by the high elevation snowpacks and reservoirs.

My 16.5″ does compare favorably to the San Jose count of 9.43″ and 12.89″ for the S.F. Airport. I am usually between the two measurements. Once again variability proves to be the rule in Bay Area microclimates.

We are in the new season tomorrow, and my hopes will be for 20″ plus in this season to come. I know I have have missed providing reports to InMenlo the last six months!
