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 100^oF (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.
