Mid-summer around the Black Hills is warm and dry with plenty of sunshine. Rapid City sees an average of 20 clear to partly cloudy days and 75 percent of its possible sunshine in June. Humidity levels are low, and there is usually a breeze during the day, so even the hottest days are still comfortable. Early mornings are cool, so a jacket or sweater may be needed for outdoor activities. At night temps drop quite a bit as can be seen in the greater difference between the avg. high and low.
