Seasons and peak demand in Duluth
Duluth winters run from November into April, with frequent subzero nights and lake-effect snow. Summers are cool near the lake, with highs in the 70s. Heating is needed most of the year. Fall boiler and furnace service before October is essential, and steep driveways can make winter service calls slower, so plan ahead.
