Dangerously high temperatures are set to hit the Grand Canyon through early next week, with the inner canyon expected to reach a blistering 113°F on Monday. This extreme heat has prompted urgent warnings for hikers, especially in areas below 4,000 feet, where the heat is expected to make hiking treacherous and strongly discouraged.
Extreme Heat Warning for the Grand Canyon
According to the National Weather Service in Flagstaff, an Extreme Heat Warning is in effect from Saturday through Tuesday for the Grand Canyon areas below 4,000 feet.
Locations such as Phantom Ranch and Havasupai Gardens are forecast to remain well above 100°F for four consecutive days, making conditions extremely dangerous for outdoor activities, particularly hiking.
On Saturday, Phantom Ranch could hit 110°F, followed by 113°F on Sunday and Monday, with temperatures staying near 113°F on Tuesday. Even at higher elevations like Havasupai Gardens (3,800 feet), temperatures will exceed 100°F each day.
Popular rim trails, such as Bright Angel and North Kaibab, will remain cooler, with temperatures in the 80s, but hikers venturing down into the canyon will face extreme heat.
Heat Wave Across Northern Arizona
This heat wave isn’t limited to the Grand Canyon area. Other northern Arizona locations like Sedona and Kingman are also experiencing extreme temperatures. Sedona will see highs of 103°F and Kingman will hit 104°F on Monday.
Meanwhile, Grand Canyon Village and Flagstaff will have more moderate temperatures in the 80s and 90s, offering some relief from the oppressive heat of the canyon floor.
Safety Recommendations for Visitors
With the extreme heat, hiking into the Grand Canyon, particularly below 4,000 feet, is highly discouraged, especially during midday when the temperatures are at their highest.
Visitors are urged to stay on the rim where temperatures are more manageable. If hiking is absolutely necessary, make sure to carry plenty of water, take frequent breaks, and check in with park rangers before starting any activity.
Key safety tips include:
Avoid hiking into the canyon during the hottest part of the day (from late morning to early afternoon).
Always carry enough water to stay hydrated.
Stay on rim trails, which are safer during the heatwave.
Check in with park rangers for updates on trail conditions and safety advice.
Be aware that the heat could lead to heat exhaustion or heat stroke, so monitor yourself and others for symptoms.
Ongoing Heat Alerts and Potential for Further Warnings
The Extreme Heat Warning remains in effect through Tuesday evening, and further advisories may be issued if conditions worsen. Visitors are strongly urged to stay informed and adjust plans accordingly to stay safe in the heat.
