On the Salmon River, it's important to be prepared for all types of weather. Although the weather on the Main Salmon River is warm and sunny for the most part, Mother Nature will occasionally surprise us with a renewing rainstorm or cooler temperatures. Temperatures can vary, but the following chart shows average temperature and precipitation for the months of March through October.
|Mean Max. Temp||-||-||69°||78°||87°||86°||75°||-|
|Mean Min. Temp.||-||-||40°||46°||51°||48°||40°||-|
NOTE: Use this weather forecast only as a general guide. As your trip will span miles of river, this forecast from the nearest major weather station may not be indicative of the entire region where your trip will take place. Weather in the canyon may vary greatly from the surrounding cities.
TIP: Since weather conditions can be unpredictable, we recommend having a two-piece rain suit available during the day. You may wish to fold it tightly and keep it in your personal day-use dry bag. (See recommended packing list).
