Winter conditions on the South Rim can be extreme. During a storm, the canyon can become obscured by fog or clouds and is no longer visible from the rim. Be prepared for snow, icy roads and trails, and possible road closures. Winter weather typically begins by November and becomes well entrenched by December and January, with frequent light to moderate snows and increasingly colder weather. Low temperatures are generally in the teens along the Rim; however afternoon high temperatures still average in the 40s (4-9°C), due to the amount of sunshine the area receives.
