Yeah I think it's all the brick and stone around here that absorbs the heat and radiates it, especially if there is extended heat. I am probably about 150 ft from a strip of woods, but that is to my east and it would have probably made more of a difference if they were near the west side.
If we hadn't had as much rain as we have had so far this year, then we would have certainly reached triple digits this summer, which will probably not happen this year given the pattern (unless the pattern does a major change and shuts off the faucet).
AND... as I type this, I'm sitting at 90, with a 79 dp (that is bopping between 78/79).
