This is anecdotal quantification, but I lived in northern California for a few years and late June would usually be in the 100s or 110s. By August when California catches on fire, it cools down to 90s (when the smoke was blowing our way). By contrast, when I lived in Texas (no fires), June and July would be in the low 100s, and the first two weeks of August would be 107 - 112.
