Weather in March

March is cold at the start of the spring season in South Dakota. It is a little damp with 1" (25mm) to 1.5" (38mm) of rain - the eastern part of the state receives more rain than the west. Average temperatures are between 20°F (-6.7°C) to 53°F (11.7°C) with western South Dakota warmer than the eastern portion. Watertown in the east has average temperatures in the cold 20°F (-6.7°C) to 39°F (3.9°C), while Hot Springs in the west is a little warm during the day and between 24°F (-4.4°C) to 53°F (11.7°C).
Snowfall is persistent, and most of the areas register 5" (127mm) to 6" (152mm). Humidity is 60%, while there is an average of 14 sunny days.
Early spring spots wildlife in many places like the Black Hills National Forest and Custer State Park. Bears, bison, coyotes, as well as birds, forage for food during the spring after the long winter cold, and it is an excellent idea to carry a repellent spray and stay away from them. Carry a raincoat or jacket, as the conditions are often wet and unpredictable!
