How is the temperature at Fenway for show time in August?
Depends on what the weather's like. Plus, it's New England, lol.

The Heart show is Aug. 5th, so...
First week of August, assuming we don't get a heat wave, it'll still be in the low to mid 80's even around 7 or 8 pm... unless it rains at some point that day.
However, if the show had been a week or two later, it'd be either rather nice or maybe even just a bit chilly since the temps would start dropping rapidly once it got past late afternoon. Anywhere from mid-70's on the high end down almost to the mid-50's if it's rainy and windy.
