Statistically speaking, this is the hottest week of the year in Baltimore. The 30-year-average high temperature at BWI-Marshall is 88 degrees, while the average low is a balmy 66. Our hottest days lag behind peak solar heating, around the solstice, thanks to the slow warming and cooling of the air and ocean. We've been lucky with heat so far this summer. But now that I've said it, we're surely in for some scorchers.
