Weather in April

April sees the advent of spring in entire South Dakota and mild day temperatures. Day temperatures are usually in the warm 50°F (10°C) to 60°F (15.6°C), while nights rise above freezing and are in the 32°F (0°C) to 35°F (1.7°C) across the state. Wind Cave National Park in western South Dakota averages between 31°F (-0.6°C) to 58°F (14.4°C) and sees a slight rise in tourist numbers.
Rivers, lakes, and streams start to meltdown, and the sound and smell of freshwater are soothing in the backdrop of the mountains. Expect wet conditions and rain anytime - the rainfall is 2" (51mm) to 3" (76mm), while snowfall is in the range of 3" (76mm) to 4" (102mm) in the majority of the state.
It is also the start of the hunting season in South Dakota - the eastern part has light geese, which serve the purpose, and it is a good idea to wear bright color clothes in the season to avoid a hunting accident. Wear layers of clothing when exploring the forests and parks or kayaking in the canyon waters.
