Clark County Has Investigated 260 Heat-Related Deaths So Far in 2026

by Ryan Rose

What Happened

The Clark County Office of the Coroner released an updated report on deaths where heat played a role in 2026. According to News 3 Las Vegas, the office has investigated 260 such deaths so far this year.

The report itself only lists cases where two things are done. First, the person has been positively identified. Second, the family, or next of kin, has been told. That group adds up to 218 cases. There are 42 more cases the office is aware of, but they are not in the report yet because the identification or family notice is still pending. Add those together and you get 260.

The coroner's office was clear that these numbers are not final. Death investigations take time. The office said 90 percent of cases take up to 90 days to find the cause and manner of death. That means some deaths from July and August may still be under review today. The final 2026 total will likely not be known until well into next year.

The office also shared what tends to raise a person's risk. Certain drugs can make the body much more likely to suffer from heat, and fentanyl was named as one of them. Health problems matter too, especially heart disease. Behaviors play a part as well. The coroner listed heavy physical exertion, wearing the wrong clothing for the heat, not being used to the heat, and not drinking enough fluids.

None of those risk factors are rare. Plenty of people in the valley have a heart condition. Plenty of people work outside, walk to the bus, or do yard work on a hot afternoon. Plenty of people forget to drink water. That is exactly why this report should get everyone's attention.

Why It Matters to Las Vegas Residents

Most of us know Las Vegas is hot. We joke about it. We plan our errands around it. But a number like 260 turns the joke into something real. These are our neighbors, and many of these deaths may have been preventable.

The Southern Nevada Health District has called heat-related illness a preventable public health issue. It has also said heat hits some groups harder than others, including older adults, people who use substances and people who do not have stable housing. The CDC adds people with heart disease, pregnant women, infants and young children, and people who work or exercise outside. If you live in Clark County, you almost surely know someone on that list.

Think about the older couple across the street who rarely leave the house. Think about the neighbor who lives alone and runs the A/C sparingly to save on the power bill. Think about the teenager who mows lawns for extra money, or the friend who works construction. Heat risk is not just a problem for people sleeping outside. It can happen inside a home when the air conditioner breaks, or when someone does not want to run it.

There is also a housing side to this story. In the Las Vegas Valley, a working air conditioner is not a luxury. It is a safety system, just like a smoke detector. When an A/C unit fails in July, the inside of a home can heat up fast. For someone who is older or has a health condition, that can become dangerous in a matter of hours.

Renters face their own version of this problem. If you rent and your A/C stops working, tell your landlord or property manager right away and put it in writing, with the date and time. Keep a copy. Then make a plan to stay somewhere cool until it is fixed. Do not wait it out in a hot apartment and hope for the best.

Finally, the season is not over just because the kids are back in school. Late September and early October can still bring warm afternoons. And because death investigations take so long, the full picture of this summer will not be clear for months. The best time to plan for next summer is now, while it is fresh in our minds.

Background and History

Heat deaths have been a growing concern in Southern Nevada for years. The Southern Nevada Health District reported 513 heat-associated deaths in Clark County in 2024. That was a record-breaking year for heat. The Health District says the summer of 2024 was the hottest ever recorded in Southern Nevada. The average high was 107.6 degrees, there was a record stretch of days above 110, and the temperature hit 120 degrees on July 7. The Health District also counted more than 3,500 emergency room visits in the region tied to heat exposure that year.

In 2025, the Health District reported 284 heat-associated deaths in Clark County. That was a 45 percent drop from 2024. About 21 percent of those deaths involved people who did not live in Clark County. The Health District called the decrease encouraging, but said awareness and preparation still matter a great deal. It also noted that 2025 was the fifth warmest year on record for Las Vegas, with 77 days at or above 100 degrees.

It is worth being careful when comparing these numbers. The 2024 and 2025 totals come from the Health District. The 2026 count of 260 comes from the coroner's office, and it only covers deaths investigated so far this year. Different offices track and report these numbers in different ways. So the figures are not a perfect side-by-side match. Still, 260 with many cases pending is a sobering number when last year's full-year Health District count was 284.

This year also started warm. In March, the Health District warned that triple-digit temperatures could arrive earlier than usual. It said the average temperature through March 15, 2026, was 57.6 degrees, the highest on record for that time of year. The Health District runs a campaign called "Beat the Heat Southern Nevada" with fact sheets and safety tips in English and Spanish.

What Happens Next

The coroner's office will keep working through open cases. As identifications are confirmed and families are notified, some of the 42 pending cases will move into the official report. New cases from late summer may also be added as investigations wrap up. Because 90 percent of cases can take up to 90 days, the count could keep changing through the end of the year.

For residents, the next few months are a window to get ready. Fall and winter are the slow season for heating and cooling companies in the valley. That makes it a good time to have your system looked at, fix small problems before they become big ones, and think about whether an older unit needs to be replaced before next summer. It is much easier to schedule service in November than in the middle of a July heat wave, when every company in town is booked.

Homeowners can also use the cooler months for bigger projects that keep a house cooler all summer. Sun screens on west- and south-facing windows, added attic insulation, sealing gaps around doors, and ceiling fans in the main living spaces can all take pressure off an A/C system. None of these replace a working air conditioner, but they help the home hold its cool longer if the power goes out or the unit struggles on a hot afternoon.

It is also a good time for families to talk. Who in your circle is most at risk? Who lives alone? Who would you call if the power went out on a 112-degree day? Having that plan in place before the heat returns can make a real difference. Keep an eye on future updates from the coroner's office and the Southern Nevada Health District as the final 2026 numbers come in.

When those updates arrive, read them with a little care. A rising count does not always mean more people died this week. Often it means older cases finished their review and were added to the list. The number that matters most will be the final one for the full year, and the lessons it teaches us about who was most at risk and what could have helped. Until then, the safest move is to act as if next summer will be just as hard as this one.

Ryan's Take

I help people buy and sell homes all over this valley, and I walk through a lot of houses in the summer. I can tell you that the A/C system is one of the first things I look at, and one of the first things I tell buyers to ask about. How old is it? When was it last serviced? Is it sized right for the house? In most places, those are comfort questions. In Las Vegas, they are safety questions. A 20-year-old unit on a two-story home with west-facing windows can struggle on the hottest days, and that matters most for older owners and families with young kids.

If you are buying, put the HVAC inspection high on your list and ask for service records. If you are selling, a recent tune-up and a clean filter tell buyers the home has been cared for. And if you are just living your life here like the rest of us, treat your air conditioner the way you treat your car. Service it before it breaks, not after. The number in this report is a reminder that in the desert, a cool home is a safe home. Look out for each other.

What You Can Do

Take care of your A/C. Change or clean your air filter often during the hot months. A clogged filter makes the system work harder and cool less. Keep the outdoor unit clear of weeds, trash and gravel so it can breathe. Schedule a professional check-up once a year, ideally in the cooler months. Watch for warning signs like warm air from the vents, strange noises, ice on the lines or a system that turns on and off over and over. Keep blinds and curtains closed on sunny sides of the house during the afternoon.

Know when a fan is not enough. The CDC says fans can help when indoor temperatures are below 90 degrees. Above 90, a fan can actually raise your body temperature. If your home is that hot, go somewhere with air conditioning. You can dial 2-1-1 to find a cooling location, or contact your local health department.

Check on your neighbors. Both the Health District and the CDC say to check on neighbors, especially older adults and anyone who lives alone or has a chronic health problem. A quick knock or a phone call on the hottest days goes a long way. Ask if their A/C is working. Ask if they have water. Offer a ride to a cool place if they need one.

Drink water and learn the signs. Drink water regularly, even when you are not thirsty. Limit alcohol, which can dry you out. Carry water and a phone when you head outside. Plan outdoor work for early morning or evening. Wear light, loose clothing and a hat. The Health District lists heavy sweating, pale skin, muscle cramps and dizziness as signs of heat exhaustion. The CDC adds headaches, weakness, nausea and shortness of breath. If symptoms get worse or someone may have heat stroke, get medical help right away.

Pace yourself outside. The coroner's office named heavy exertion and not being used to the heat as risk factors. If you are new to Las Vegas, give your body time to adjust. If you work outside, take breaks in the shade, drink water before you feel thirsty, and watch your coworkers for signs of trouble. If you run, hike or bike, go early in the morning. Red Rock and the trails around Henderson will still be there when it cools off.

Know where fentanyl fits in. The coroner's office warned that certain drugs, including fentanyl, can make people more likely to die from heat. If someone you love uses substances, the hottest days are a time to check in more often, not less. Make sure they have water, shade and a cool place to go.

Have a plan for power outages and medicine. The CDC notes that many medicines can make you more likely to get dehydrated or overheated. Do not stop or change a medicine without talking to your doctor. If you rely on medicine that must stay cold, or on a medical device that needs power, make a backup plan now. And never leave children or pets in a car. The Health District warns the inside of a car can reach 120 degrees even when it is only in the 90s outside.
