Climate

General Climate

The Grand Canyon is a natural chasm of the most incredible proportions. It's size likens it to something like an "inverted mountain" caved within the earth over billions of years. Just like a towering mountain range, the Grand Canyon varies greatly in temperature depending on the season - or even where one is standing. In the summertime, temperatures can reach as high as 80 degrees Fahrenheit, and in the winter as low as 30 degrees Fahrenheit. The South Rim is typically warmer than the North Rim, which sees snow much more commonly due to its higher elevation. The canyon floor is usually the warmest part of the canyon. This is because the massive canyon walls are exposed to the Sun all day and can retain the heat from its rays. Depending on the way one tours the canyon, it is wise to dress in layers or pack a jacket in the likely possibility that you will experience a temperature change.

North Rim

The North Rim sits approximately 1,500 feet higher in elevation than the South Rim, making it noticeably colder in the winter and much damper during the summer monsoon season. Summer temperatures can reach 75 degrees Fahrenheit, and can drop to 40 degrees in the wintertime. The winter season can bring up to 200 inches of snow to the North Rim, at times 6-10 feet deep. Because of this, this area of the canyon closes for a large portion of the year, from around October 16th to May 15th. The higher altitude of the North Rim also means a slightly lower air density, which is important for elderly travelers to bear in mind when visiting.

South Rim

The South Rim boasts yearlong pleasant weather, receiving less than 16 inches of precipitation annually with very mild snowfalls. Temperatures here range from a comfortable 70-84 degrees Fahrenheit in the summer to 40-50 degrees Fahrenheit in the winter. A sheer contrast to the remote and chilly North Rim, the generally agreeable weather of the South Rim undoubtedly plays a role in its popularity among guests.

Inner Gorge

The Inner Gorge is the deepest area of the canyon, where the oldest and most ancient rock is exposed. This 1.7 billion-year-old cut of the Earth experiences major temperature changes throughout the year. The sun is higher in the summer and its rays can reach all the way down to the Inner Gorge,literally baking the stone walls. This can create air temperatures of up to 106 degrees Fahrenheit. The winter sun, however, does not rise high enough to reach that deep into the canyon. In January, temperatures can drop as low as 35 degrees Fahrenheit in the Inner Gorge. Because such seasonal variations in temperature are to be expected, it is wise to plan your trip to the Inner Gorge according to the weather you would most like to experience.

Monsoons

Monsoons are seasons of strong winds usually accompanied by intense rain. At the Grand Canyon, monsoon season typically begins in July and carries on through the summer, with August being the wettest year of the month. These heavy rains can build up and spread across the desert landscapes, overwhelming the canyon gullies and creating flash flooding throughout the park. It is imperative that campers and hikers visiting in the summer are prepared for inclement weather and use caution during what could be potentially dangerous storms.

Average Precipitation

The North Rim receives approximately 25.6"/652mm precipitation per year. The South Rim receives an average of 14.4"/366mm per year, and Phantom Ranch, located within the Inner Gorge of the Grand Canyon, receives 9.4"/239mm per year.

Sunrise and Sunset at the Canyon

There are few places on Earth that can match the spectacular sight of the sunrise and sunset at the Grand Canyon. The red, pink, purple, and orange skies merging with the magnificent rock layers of the canyon is a sight to behold, perhaps only once in a lifetime. The South Rim offers several phenomenal vantage points, either early in the morning or in the evening before nightfall. At the North Rim, areas of the Grand Canyon Lodge and Bright Angel Point provide equally beautiful views.
