Emergency workers say they're already seeing the effects of this week's heat and humidity.
Bay County Emergency Medical Services (EMS) have treated three heat stroke victims so far in the past two days. That's half the number they usually see in a whole season.
Severe heat stroke can cause brain damage or even death, but none of the recent cases have been that serious.
Young children, the elderly, and people with heart conditions are the most vulnerable to the heat, but EMS Director Randy Vick says it can get to anyone.
"A lot of times it's people that are working outside that don't take time to take an adequate break. It's also people that are used to working inside and suddenly decide they're going to go jogging or they're going to work outside in the middle of the day."
Vick says it's important to recognize the warning signs of heat stroke. If you start having cramps, feeling dizzy and feel dehydrated, it's time to get out of the heat.
The best way to prevent heat stroke is to wear light weight and light color clothes. Take frequent breaks to get into the shade or indoors, and to drink plenty of water.
Vick says if you know someone who doesn't have air conditioning in their home, it's a good idea to check on them regularly.
