South Dakota Weather & Climate Guide 2026

South Dakota's climate in numbers — the months that flatter it, the ones to avoid, and what to pack.

South Dakota is the Mount Rushmore State, a land of sweeping Great Plains, dramatic Badlands formations, and the storied Black Hills. From the granite faces of four presidents to the fossil-rich Badlands, the buffalo herds of Custer State Park, and the raucous saloons of Deadwood, South Dakota rewards travelers with authentic American West experiences far from the usual tourist circuits.
