Despite above normal temperatures in other places around the globe, maximum daytime temperatures in Southern California were between two and six degrees below normal during the April through October period, which is typically the warm half of the year. Overall temperatures in the region averaged about two degrees below normal.
Ocean temperatures between Los Angeles, Orange and San Diego counties also averaged about five to 10 degrees below normal according to the National Oceanic and Atmospheric Administration.
These temperatures were caused by an upper level trough that had maintained a significant marine influence across coastal and valley areas of southwestern California, according to the National Weather Service of Los Angeles and Oxnard.
“With ocean temperatures that are much colder than normal, the cold summer temperatures we observed, especially along the coast, are not surprising, given the strong influence the ocean has on our climate,” said James Miller, an assistant professor in the Department of Geography.

Look at the huge influence of UHI in Southern California. How cold would California be if this contamination of extra UHI heat were removed from the data?

If I recall, the thermometer malfunctioned shortly after that reading took place. Someone must have lit a match under it!
Gosh, what UHI can do!
