Key Climate Data Points

• Annual average temperature: roughly 43–46°F in the Bismarck–Mandan river corridor.
• Annual snowfall: commonly 30–45 inches, although wind redistributes snow and creates deep drifts beside exposed roads.
• Warmest months: July is usually warmest; exposed badlands and prairie heat faster than wooded or lakeshore settings.
• Coolest months: January is generally coldest, with wind chill often more important than air temperature.
• Wettest season: Late spring and early summer usually bring the most precipitation, including severe thunderstorms.
• Driest season: Winter is often driest by liquid precipitation, although drifting snow can dominate access.
• Best outdoor window: Late spring through early fall for warm-season activities; winter destinations require verified ice, snow, roads, and operations.
