Seasons & Weather
Deadwood sits at about 4,670 feet in the Black Hills, so nights stay cool and snow comes early and leaves late.
Season by season
Summer is the busiest time, with warm days that can reach 90°F. July is the warmest month on average.
Fall brings gold aspen and birch to the hills, and the first snow can arrive in October.
Winter is cold, with average lows near 14°F. Nearby high country gets plenty of snow for snowmobiling and skiing.
Spring is changeable. April can still bring heavy snow, and May is usually the wettest month.
