Late June in Butte brings classic Montana mountain weather. Race day typically starts cool in the high 40s°F at 4:00am before warming to the mid-70s during the afternoon, with strong high-altitude sun and dry air that accelerates dehydration. Overnight, temperatures at the course's highest elevations near Our Lady of the Rockies (8,400 ft) can drop into the 20s°F, creating a 40–50°F swing across the 40-hour event. Afternoon thunderstorms are common in the summer mountains and arrive quickly. Past editions have included overnight thunder snowstorms (2023) and refreshing light rain during the day (2025).
