Fun weather facts about the Canyon

It spans over a mile in elevation, causing dramatic temperature changes between the rim and the river.
On the same day, temperatures can vary by 30°F (17°C) or more between the South Rim and Phantom Ranch.
In summer, the Inner Canyon often reaches over 110°F (43°C), while the South Rim might stay in the 80s (27°C).
Snowfall is common at the South Rim in winter, but the bottom of the canyon rarely sees snow.
The South Rim's highest recorded temperature is 105°F (41°C), and the lowest is -20°F (-29°C)
Monsoon storms in July and August can bring sudden downpours, lightning, and even flash floods.
The North Rim is 1,000 feet higher than the South Rim and, on average, 10–15°F (6–8°C) cooler.
Clear skies and dry air make the Grand Canyon one of the best stargazing spots in the U.S.
Despite its desert-like appearance, the Grand Canyon has over 16 inches of precipitation annually at the North Rim.
Due to its vastness and elevation differences, the weather can change quickly, making preparedness essential for visitors.

Seasons in the Grand Canyon

Spring brings ideal hiking weather and the reopening of seasonal services. Snow begins to melt on the South Rim, trails become accessible, and wildflowers bloom across the canyon’s plateaus. The North Rim remains closed until mid-May, but the South Rim and Inner Canyon are excellent for early-season adventures.

Things to do:

Hike the Bright Angel or South Kaibab Trails

Pack for the weather

🌸 Spring (March–May)

The weather can swing between chilly mornings and warm afternoons. It is advised to pack layers, including a fleece or light jacket, plus sun protection like a hat and sunscreen. Hiking boots with good traction are essential for thawing, sometimes muddy trails.
