When it gets hot in the Southern Arizona people look for places to take a dip and cool off.
Local hot spots in Tucson?
Seven Falls and Tanque Verde Falls are local favorites but can be deadly during monsoon.
During the summer months, heat exhaustion isn't the only thing a hiker needs to worry about.
"Be aware of avoiding the deep canyons, the narrow canyons, any time there's the possibility of a flash flood coming down. Avoid the tight canyons stay in the wide canyons," said Andy Lamb with the Southern Arizona Rescue Association.
During Monsoon hikers need to be concerned about water basins flowing up in the mountains.
While it takes a couple of hours for the water to come down, it takes just minutes to rise and become a dangerous situation.
Lamb says, "It can be deadly because it can be completely dry, no rain or anything and then all of a sudden there's a rush of water coming down the canyon."
The water from the basin usually travels 10-15 miles an hour.
Rescuers say, if you plan on going into canyons, you should always have a plan.
"Be aware of where you're at and make sure you have an escape route. There's places in Tanque Verde falls that if you're caught in there, there's nowhere to escape," said Lamb.
In 2017, 17 hikers were rescued from Tanque Verde falls and a father and child were clinging from a tree.
In Sabino Canyon, 26 hikers were rescued after being stranded by high, fast-moving waters in 2017.
