Buffalo Weather in September

Buffalo at the eastern end of Lake Erie is America's lake-effect snow capital. When cold Arctic air sweeps across Lake Erie and hits Buffalo, it can dump feet of snow in hours — the 2022 blizzard killed over 40 people. Yet the lake also moderates temperatures, keeping Buffalo's winters less extreme than cities farther from the water when lake-effect isn't happening.

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