Grand Canyon Weather
There is no single Grand Canyon forecast. The South Rim, North Rim, and Colorado River can feel like different seasons on the same day. Compare live conditions at three elevations before you choose a hike, pack the car, or decide how to spend the day.
Phantom Ranch Is a Weather Reference Point
The inner-canyon forecast uses Phantom Ranch elevation for temperature context, not as an access indicator. Current NPS hiking guidance lists Bright Angel Trail open from the South Rim to River Resthouse, Plateau Point Trail open to Plateau Point, South Kaibab Trail open only to Tip-Off, and the Tonto Trail open between Tip-Off and Havasupai Gardens. The North Kaibab Trail, Black Bridge, Silver Bridge and Phantom Ranch remain closed. Use the weather data here for elevation context, then check current NPS hiking messages and alerts before planning any below-rim route.

Why One Forecast Is Not Enough
Grand Canyon National Park spans thousands of feet of elevation. The National Park Service notes that temperature generally rises about 5.5°F for every 1,000 feet you descend. That is why a comfortable afternoon on the rim can become dangerous heat near the river.
South Rim
Around 7,000 feet, Grand Canyon Village is the forecast that matters most for the park's main visitor area, viewpoints, shuttles, lodging, and South Rim roads.
North Rim
Around 8,000 feet, the North Rim is usually cooler and receives substantially more winter snow. Access and services are also more seasonal.
Inner Canyon
At roughly 2,460 feet, Phantom Ranch represents the much hotter canyon floor. In summer, the temperature difference from the rims can be dramatic.
Conditions That Deserve More Than a Forecast
A temperature icon cannot tell you whether a trail is closed, a road is icy, or a thunderstorm has created a flash-flood hazard. Use the forecast to plan the day, then use live park sources to decide whether the plan is still safe and practical.
Summer Heat
The inner canyon can be far hotter than either rim. A mild-looking rim forecast is not a reliable guide to hiking conditions thousands of feet below.
Monsoon Storms
Late-summer thunderstorms can build quickly and bring lightning, intense localized rain, strong winds, and flash flooding. Conditions can differ sharply across short distances.
Winter Snow & Ice
Rim elevations can receive significant snow. Roads and trails may become icy, visibility can fall quickly, and temporary road closures are possible during storms.
Before You Commit to the Day
Check the forecast here for orientation. Before a hike, winter drive, or weather-sensitive activity, confirm official park alerts, road status, trail conditions, and National Weather Service hazard information.
Weather by Season
Understand what winter, spring, summer, monsoon season, and fall usually mean for a Grand Canyon trip.
Park Alerts
Check closures, emergency notices, fire activity, and visitor-impacting updates before you go.
Road Conditions
Winter storms and other events can change driving conditions faster than a general forecast suggests.
How to Use This Page
