Overall the summer of 2016 was a real mixed bag in regards to California temperatures. The average maximum temperatures anomalies for meteorological summer (i.e., Jun-Jul-Aug) ranged from below normal near the coast from about San Francisco north to above normal over most of the remainder of the state. (http://ggweather.com/calif/summer2016.htm). It should be noted that in San Jose the average summer temperature was right on "normal" with an anomaly of zero!
The average summer maxima for the past seven years has likewise been mixed, with no year showing the same (i.e., positive or negative) anomaly for all 8 cities. And only Fresno had the same, in this case positive, for all seven years. (Below)
