According to the "UCDavis, that information would come from weather Station #211 Gilroy http://fruitsandnuts.ucdavis.edu/Weather_Services/chilling_accumulation_models/Chill_Calculators/ind... This site has a wealth of information about chill hours and how to calculate their effect on harvest. According to the calculator on that site, the Los Altos area experienced a total of 337 hours below 45 degrees in 2015, 163 in 2014, 502 in 2013 and 222 in 2012 - so that is your general range.
