When hiking, always be aware of your surroundings and current weather conditions.
Don't be so committed to your hike that you refuse to recognize a dangerous situation. Northern Arizona is an incredibly diverse area with may things to do and see. When weather threatens, postponing your hike for a day or two and finding something else to do is a wise decision that could save your life. Be willing to change your plans.
Average Temperatures in the Inner Canyon
Before you begin any hike ALWAYS CHECK THE WEATHER FORECAST. Watch continually for changing weather conditions during your hike. Average temperatures, weather information, and road conditions can be found on the Weather Conditions page.
The National Park Service urges SPECIAL CAUTION for all hikers during the summer months. Daytime highs can potentially top 120F. These temperatures are beyond unpleasant or uncomfortable-they are, in fact, dangerous and if you fail to factor the heat into your plans the results could be tragic.

Flash floods, which have been described as "more water than you want in less time than you have," are common in Northern Arizona. This is because the arid, sparsely vegetated environments found in this area have little capacity to absorb rainfall. The resulting runoff moves rapidly through the narrow canyons and steep terrain found throughout Northern Arizona. In many areas, even small storms can turn normally dry streambeds into raging torrents of water in a matter of minutes.
A flash flood can travel miles beyond the rainfall that generated it, catching unwary hikers and motorists by surprise. In Lower Antelope Canyon on August 12, 1997, twelve hikers were caught in a flash flood that filled the narrow canyon with water up to 50 feet deep. The hikers did not recognize the flood danger until it was too late, probably because the storm that caused the flood occurred miles away. Only one hiker survived!
