Fargo Weather in September

Fargo on the Red River of the North is one of America's coldest cities, where continental Arctic air masses arrive with nothing to stop them across the Canadian Plains. Winter temperatures of -40°F are not uncommon and blizzards can be severe. The Red River Valley's flat terrain and rich soil mean spring flooding is an annual threat that has shaped the city's flood protection system.

Excellent shoulder season — warm with fewer tourists in many destinations.
