The warmer weather means more people outdoors, which also means a greater risk for heat-related injuries.
Officials are warning the community to be prepared and stay vigilant.
"I would just highly encourage people to stay hydrated, drink plenty of water," said Fresno County Sheriff's Office Lieutenant Sergio Garcia.
Some parents celebrating Mother's Day at Woodward Park on Sunday told Action News they hope calling 911 is a last resort. They say it's best to take preventive measures.
"Just remind them to keep drinking not only water, but other drinks. And take breaks when they're playing outside," said Harjimber Dhesi, a father.
Pediatricians say hydration and shade are some of the best ways to keep everyone safe to prevent any signs of heat exhaustion from turning into heat stroke.
"That's when we would see, like, the really high fever, some muscle cramps, confusion, or just a child not acting like themselves," said Dr. Sanskriti Saxena, a Pediatric Resident at Valley Children's Hospital.
Doctors say that severe dehydration can happen when someone is running around and sweating in high temperatures, depleting their body's electrolytes.
"That's what causes our heat cramps. So sometimes, we can feel it in our legs, sometimes in our arms," said Valley Children's Dr. Gino Urbano.
To prevent reaching that point, they recommend not only water but also unsweetened drinks to replenish them.
Experts also recommend wearing loose clothing and sunscreen to avoid heat-related injuries.
Overall, officials say the best thing to do is stay in groups and keep an eye on one another, especially children.
"Keeping constant supervision of your children. Avoid any distractions at all costs. Especially in open areas," said Garcia.
Officials say other heat-related injuries, sometimes overlooked, occur on playgrounds.
Metals or plastics out in the sun can leave burns when touched.
The City of Fresno does offer cooling centers but they are activated only when temperatures reach 105 degrees.
