I think part of it too has to do with maybe expectations or just forgetting what the average high temperature is for much of June. I'm guessing early June the average high probably ranges anywhere from upper 60's to maybe lower 70's and then by mid-June mid 70's to lower 80's. Sure it's not uncommon at all to get days or stretches of mid-to-upper 80's with maybe some lower 90's in the typical hot spot locations, but when comparing to average mid-to-upper 80's in June is considered very warm to hot depending on where you are.
