February is a chilly winter month in South Dakota as the landscape wrestles with the cold conditions. Nights are severely cold, and the entire state registers low freezing temperatures. The sunshine is usually weak and lasts for short periods in the dry and cold conditions. Sioux Falls, in the far southeast hardly sees the sunshine with the average temperatures in the 12°F (-11.1°C) to 31°F (-0.6°C) range, while Rapid City and Spearfish on the western part of the I-90 are between 18°F (-7.8°C) to 39°F (3.9°C) and 20°F (-6.7°C) to 41°F (5°C) respectively. Blizzards are common, deposit layers of snow and ice, and stall many towns and cities due to poor visibility and dangerous roads. Snowfall is 5" (127mm) to 7" (178mm) in the majority of the state. Most flora and fauna are asleep, and there are few reasons to visit South Dakota in February apart from ice fishing, ice-skating, and the likes - winter conditions close the mountain trails.
