The wettest day on record, 8.05 inches on September 29, 2023, shows how vulnerable the area is to late-season storms, and a single January 2016 storm buried the town under 30.3 inches of snow.
Summer is the sweet spot, with highs peaking around 83–85° in mid-July before cooling quickly through fall. Winters are cold but not brutal, with average January highs hovering near 38–39°.
