Custer City and the Black Hills of South Dakota are home to full calendar of weather with four truly distinct seasons. Expect warm to hot summers, pleasant spring and fall weather, and cold winters with lots of snow.

January is the average coldest month in the region, while July is on average the warmest month. The spring and fall can be pleasant with mild temperatures during the daytime, and evenings that are a bit cooler. Summers are warm and dry in Custer and City, and typically temperatures climb into the mid to upper 80s during the day, and cool down after the sun goes down in the low to mid 60s at night. The summers can be dry with little to no rainfall, and the occasional heat wave can spike temperatures well into the 90s. Summers are the time of swimming in the various rivers; mountain biking in the woods or hiking on the area’s numerous trails. Likewise, many of the attractions in the region, including the amusement parks and other outdoor activities are open from May through October.

During the winter it is uncommon for the region to get heavy snowfall, with periods below freezing. But this time of year isn’t a total dead season, and this is when the activities in the great outdoors turn to ice-skating, skiing and snowmobiling.
