August here in Two Harbors has temps/precip below avg at 63.9 (65.3), and 2.72" (3.48"). Precip is right about avg for the year now at 21.89" (21.42").
Summer was on the cooler side with 60.8 (62.1), and drier with 9.36" (11.76"). With the Lake being so much cooler this year, it had a big effect on temps here, and the weather pattern really helped it stay that way through the summer with so many cooler, drier nights. In looking at the data, we really didn't see a steady stream of warmer nights until mid August. The lower humidity allows for more cooling at night.
