Learn moreA Genuine Humid Continental Climate, With Very Strong Seasonal Contrasts
Green Bay's climate delivers real, distinct experience across all four seasons: typical temperatures range from approximately 12°F to 81°F across the year, rarely falling below -7°F or exceeding 89°F -- a genuine humid continental pattern per NOAA's own climate normals.
Genuinely Cold, Snowy Winters -- Above the National Average
Green Bay averages 55.6 inches of snow annually per NOAA's 1991-2020 climate normals -- well above the national average, and a real, defining winter-weather fact this record does not soften.
Real Lake-Effect Snow Enhancement From the Bay of Green Bay
The Bay of Green Bay and broader Lake Michigan proximity contribute real lake-effect snow enhancement to the region -- most pronounced across nearby Door County to the north and east, but a real, relevant factor for Green Bay itself given its position at the bay's southern mouth.
Wisconsin's Real Statewide Cold-Wave Hazard Is Directly Relevant Here
As detailed on the flood-hurricane-risk topic page and per the Wisconsin market manifest's own research context, Wisconsin's single highest Expected-Annual-Loss hazard statewide is genuinely cold wave -- directly relevant given Green Bay's own genuinely cold winters documented here, not just a statewide abstraction.
Confirm Current NOAA Seasonal Normals for Precise Planning
Movers should confirm current NOAA/National Weather Service seasonal-normal data directly for precise winter-preparation and moving-timeline planning, since specific-year conditions can vary from the long-term climate normals cited here.
