Extreme heat continues to impact the Grand Canyon, with temperatures reaching as high as 113°F at Phantom Ranch and 101°F at Havasupai Gardens.
This heat wave, which is expected to last through Sunday, August 4, is putting visitors and hikers at significant risk, especially in exposed areas below 4,000 feet.
Extreme Heat Conditions at the Grand Canyon
The National Weather Service in Flagstaff has issued an Extreme Heat Warning for all lower-elevation areas of the Grand Canyon, including popular trails and campgrounds.
With temperatures in the low 100s, this is among the most dangerous heat of the year for the park, particularly for those hiking or camping in exposed regions.
Park officials recommend avoiding strenuous outdoor activities between 10 a.m. and 4 p.m. and suggest that hikers not descend more than 1.5 miles from the Bright Angel Trailhead. Visitors are urged to carry extra water, use sunscreen, and eat more calories to avoid dehydration and exhaustion.
Safety Tips for Visitors and Hikers
For those staying at Phantom Ranch, Grand Canyon Village, or hiking near Havasupai Gardens, safety is a top priority. The heat is especially dangerous for visitors without access to shade or cooling. Emergency crews and park rangers are on high alert, encouraging all guests to “hike smart” by:
Taking frequent breaks in shaded areas.
Wearing wide-brimmed hats to protect from the sun.
Eating salty snacks and drinking electrolytes to prevent dehydration.
If you experience symptoms of heat exhaustion or heat stroke, it’s essential to seek immediate help. Heat stroke is a medical emergency and requires a 911 call. Be sure to stay hydrated and take precautions to protect yourself from the extreme temperatures.
With extreme temperatures expected to last through August 4, visitors to the Grand Canyon are advised to exercise extreme caution.
By staying informed, preparing for the heat, and following park safety guidelines, you can help ensure your safety during this dangerous heat wave.
