Bismarck Weather, When to Go and Climate Information

(Bismarck, North Dakota - ND, USA)



The climate in the city of Bismarck is very much influenced by its location in the Great Plains, close to the very geographical center of America, on the northern side of North America. The sunny weather is reliably warm, while the winter months are particularly harsh.

Throughout the year, the temperatures experienced in Bismarck can prove to be quite variable, with four very distinct seasons. July experiences the warmest climate, when temperatures are known to rise as high as 29°C / 84°F or 30°C / 86°F during the hottest, sunniest weather.

Either side of July, the months of June and August regularly enjoy temperatures over 20°C / 68°F, peaking at 25°C / 77°F or more. Rainfall is at its highest during the summer months, with precipitation levels rising between May and September. However, Bismarck is far from being considered a wet city.


Seasonal Climate Variations / When to Go

If you are visiting Bismarck during December and January, you can expect periods of days when the temperature doesn't rise much above freezing, if at all. By night, icy weather arrives and temperatures frequently drop below -10°C / 14°F.

Due to the rather chilly winter climate, cars are often fitted with block heaters, which help engines to start easier during the coldest weather and warm the vehicle more quickly. Worth noting, some block heaters in rental cars may require an external power source.

As the month of March nears an end, the daytime temperatures soon begin to rise noticeably and the 'big thaw' starts to make itself known. By April, temperatures are soon topping 10°C / 50°F or 12°C / 54°F, with daylight hours increasing. Visiting in April or May offers a very different character to the state capital of Bismarck than a summer vacation, with the city being fresher and quieter.
