Las Vegas heat is not ordinary summer weather. The average July high is about 104.5 °F (40.3 °C), and the city's record of 120 °F was set on July 7, 2024. The air is also very dry — the city gets only about 4.2 inches of rain a year — so sweat evaporates quickly and it is easy to underestimate how much water you are losing. The tips below are general information, not medical advice; if you have a health condition or take regular medication, ask a doctor about heat before you travel.
Water first
- Drink regularly through the day, not only when you feel thirsty.
- Carry a refillable bottle when you are out walking, and check each venue's rules on bringing one in.
- Go easy on alcohol in the afternoon, especially before an outdoor game or a long queue.
Time your day
Plan outdoor sightseeing, such as a drive through Red Rock Canyon, for early morning. Use the hottest hours for indoor rest, a pool in the shade, or a museum. Many shows start in the evening, but the walk to them can still be hot after sunset, because pavements and buildings release heat well into the night.
Walking the Strip
Distances between resorts are longer than they look, and much of the route is in full sun. Use indoor walkways and covered bridges where you can, and consider the Las Vegas Monorail on the east side of the Strip or a rideshare for longer hops. Our guide to getting around the Strip has more ideas.
Dress for it
- Light, loose, light-colored clothing and a wide-brimmed hat.
- Sunscreen, reapplied often, and sunglasses.
- Comfortable closed shoes: sidewalks can become very hot.
- A light layer for the evening, as theaters and arenas are often strongly air-conditioned.
Know the warning signs
Heavy sweating, dizziness, headache, nausea, cramps or unusual tiredness can signal heat exhaustion. Move to a cool place, drink water and rest. Confusion, a very high body temperature or fainting needs urgent medical help — call 911.
Events in the heat
Domed and indoor venues like Allegiant Stadium and T-Mobile Arena are comfortable inside, but queues, tailgates and walks to the door are not. An open-air evening at Las Vegas Ballpark also needs planning. See Game Day in Las Vegas and Days Out Off the Strip for event-specific tips.
