North Dakota has a humid continental climate (Köppen climate classification Dfb) in its eastern half and a semi-arid type (Köppen BSk) in the western half. Summers are warm to hot, while winters are cold. North Dakota is a Midwestern state at the center of the continent of North America. Minnesota to the east, South Dakota to the south, Montana to the west, and the Canadian Provinces of Saskatchewan to the northwest and Manitoba to the north share borders with the state. Temperatures and rainfall vary widely due to the interior location in the continent and more than 1000 miles distance from any large water body.

North Dakota, the Peace Garden State, has an average elevation of 580 meters, with the highest point at 903 meters at White Butte. Four geographical regions prominently divide the state. The Great Plains in the southwest include the famous Badlands region along with gently rolling hills and buttes. The Missouri Coteau extends diagonally from the northwest to the south-central border and consists of steep hills. The Glaciated Plains cover the rest of the state with gentle glaciated landscapes, streams, and moraines. The Red River Valley is a glacial lake plan that extends from the eastern border and is exceptionally fertile. Western and south-central rivers and their tributaries drain into the Missouri River, while eastern and north-central ones drain into the Red River.

Summers in North Dakota summers are warm to hot, with the average high temperatures between 77°F (25°C) to 87°F (30.6°C) at the peak of July.

Winters are cold, with widespread snow cover and extremely variable temperatures. Temperatures fall below 0°F (-17.8°C) for an average of 40 to 70 days statewide. During years of little snowfall, the temperatures remain in the 40°F (4.4°C) to 60°F (15.6°C) range. Dry and cold air masses during the winter and hot and warm air in the summer result in large daily fluctuations in temperatures. Spring and autumn are relatively mild, with a caveat of extreme conditions due to frontal air passages and high winds.

The annual precipitation in North Dakota ranges from 14" (355.6mm) in the west to 22" (558.8mm) in the east.

The worst time to visit North Dakota is during the cold winter season from December to February. The winter snowpack is persistent at least till March, and the average snowfall is 51" (1295.4mm). Arctic air masses reach the heart of the state with little resistance from the north and sweep the Great Plains with impunity. Blizzards average 2 to 3 in the season and reduce visibility to a few feet. Strong winds quickly fill the air with powdery snow, and major highways remain closed during snowstorms. Extremely cold temperatures make winter travel challenging, but there are plenty of fun-filled activities for snow lovers.

North Dakota is vulnerable to thunderstorms, floods, droughts, tornadoes, and blizzards. Mountains provide a barrier on the western side to the moist air from the Pacific Ocean. The northern and southern sides of the state are open to air masses in all the seasons. Continuous wind in all seasons and temperature variations are the main features of the climate of North Dakota. Extreme cold up to -60°F (-51.1°C) and blizzards are not rare in the winter, nor are temperatures of 121°F (49.4°C) and frequent tornado outbreaks in the summer. Local floods are frequent during late spring and summer due to spring snowmelt and heavy summer rainfall. The Garrison Dam near Bismarck has significantly reduced the danger of the flooding of the Missouri River. Blizzards occasionally sweep the landscape during the cold season.

Despite its location on the northern boundary of the United States, the average snow depth rarely goes above 15" (381mm). Dense fog is prevalent during the mornings in many places, and the daily sunshine rarely lasts for 5 hours.

Powers Lake and Kenmare in the west are even colder, with temperatures between 3°F (-16.1°C) to 24°F (-4.4°C). Winter temperature variations are extreme in North Dakota due to the lack of natural barriers to the invading air masses from the north and south.
