Extreme heat days—days with temperatures exceeding 106° F—are projected to increase in Clark County. Currently, we experience about four extreme heat days per year. By 2064, that number could increase to 23 – 30 extreme heat days.
Staying cool in Clark County can be challenging, especially because not everyone experiences heat the same way. Due to the Urban Heat Island (UHI) effect, some of our neighborhoods are hotter than others. Although our extreme temperatures impact our vulnerable residents the most, everyone is exposed to extreme heat here in Clark County.
With StayCoolClarkCounty.com, we and our partners throughout the region are striving to make it easier for everyone to escape extreme heat.

Heat And Your Health
According to analysis by Southern Nevada Strong and the RTC of Southern Nevada
Hot Days Can Impact Your Health!
According to the U.S. Centers for Disease Control and Prevention (CDC), extreme heat kills more than 600 people in the United States every year, and during the years 2009-2018, heat killed nearly 600 people right here in Southern Nevada. Exposure to extreme heat can cause illness in anyone, but is particularly dangerous for infants and children, senior citizens, outdoor workers, people with chronic diseases, and unhoused individuals. For more information on heat and health, visit this page from the Southern Nevada Health District: Extreme Heat is a Potential Health Concern.
Follow These Hot Weather Tips from the CDC
Stay in an air-conditioned place as much as possible. If your home does not have air conditioning, go to the shopping mall or public library—even a few hours spent in air conditioning can help your body stay cooler when you go back into the heat. Call your local health department to see if there are any heat-relief shelters in your area.
- Keep in mind: Electric fans may provide comfort, but when the temperature is in the high 90s, they will not prevent heat-related illness. Taking a cool shower or bath or moving to an air-conditioned place is a much better way to cool off. Use your stove and oven less to maintain a cooler temperature in your home.
Sunburn affects your body’s ability to cool down and can make you dehydrated. If you must go outdoors, protect yourself from the sun by wearing a wide-brimmed hat, sunglasses, and by putting on sunscreen of SPF 15 or higher 30 minutes prior to going out. Continue to reapply it according to the package directions.
- Tip: Look for sunscreens that say “broad spectrum” or “UVA/UVB protection” on their labels- these products work best.
Cars can quickly heat up to dangerous temperatures, even with a window cracked open. While anyone left in a parked car is at risk, children are especially at risk of getting a heat stroke or dying. When traveling with children, remember to do the following:
- Never leave infants, children or pets in a parked car, even if the windows are cracked open.
- To remind yourself that a child is in the car, keep a stuffed animal in the car seat. When the child is buckled in, place the stuffed animal in the front with the driver.
- When leaving your car, check to be sure everyone is out of the car. Do not overlook any children who have fallen asleep in the car.
Drink more fluids, regardless of how active you are. Don’t wait until you’re thirsty to drink.
- Warning: If your doctor limits the amount you drink or has you on water pills, ask how much you should drink while the weather is hot.
- Stay away from very sugary or alcoholic drinks: These actually cause you to lose more body fluid. Also avoid very cold drinks, because they can cause stomach cramps.
Heavy sweating removes salt and minerals from the body that need to be replaced. A sports drink can replace the salt and minerals you lose in sweat.
- If you are on a low-salt diet, have diabetes, high blood pressure, or other chronic conditions, talk with your doctor before drinking a sports beverage or taking salt tablets.
Although anyone at any time can suffer from heat-related illness, some people are at greater risk than others:
- Infants and young children
- People 65 years of age or older
- People who are overweight
- People who overexert during work or exercise
- People who are physically ill, especially with heart disease or high blood pressure, or who take certain medications, such as for depression, insomnia, or poor circulation
Visit adults at risk at least twice a day and closely watch them for signs of heat exhaustion or heat stroke. Infants and young children, of course, need much more frequent watching.
