Warmer Summer Afternoons & Inland Snow Patterns
Duluth climbs roughly 800 feet from the Lake Superior shoreline up to the crest of the hill at Trinity Road and Miller Trunk Highway (US-53). Once you pass over the ridge into Duluth Heights and Hermantown, Lake Superior's cold marine breeze drops off dramatically.
On the exact same spring or summer afternoon, temperatures in Hermantown are frequently 10 to 15 degrees Fahrenheit warmer than down by the lakewalk—while winter storms can deposit heavier snow totals atop the ridge.
