Weather and River Level Information
Appropriate clothing and other gear should be carried from November through April as cold fronts can bring freezing weather with rain or snow. The “rainy season” extends from mid-July through early October and can result in locally heavy thunderstorms and flash floods. Rapid river rises can be dangerous if unprepared. Relative humidity is normally between 25%-40% year around.
