Central Idaho weather is typically sunny, clear, and warm with temperatures in the high 70s-80s during the day and in the 40s-50s at night. However, mountain weather can quickly change, and if it rains, it gets chilly. Sunburn is usually the biggest concern, so bring plenty of sunscreen! Water temperatures range from the low 40s in early June to the 60s in late August. The water on the Main Salmon River is usually about 10 degrees warmer than on the Middle Fork.
