Summer: Summer temperatures on the South Rim are relatively pleasant (50s to 80s oF; low teens to high 20s oC) but inner canyon temperatures are extreme; daytime highs at the river (5000 feet below the rim) often exceed 100oF (38 oC). North Rim summer temperatures are cooler than those on the South Rim due to increased elevation.

Winter: Winter conditions at the South Rim can be extreme: expect snow, icy roads and trails, and possible road closures. Canyon views may be temporarily obscured during winter storms; in such cases entrance fees are not refundable. The North Rim is closed in winter.

Spring & Fall: Spring and fall weather is extremely unpredictable; be prepared for sudden changes in the weather at those times of year.
