Las Vegas woke up early Friday, June 5, 2026, to clear skies, sticky air and a toasty 77°F at 5:35 a.m. PDT. By this afternoon, the heat gets serious, with temperatures forecast to rocket into the triple digits and top out near 107°F, followed by only a warm overnight cool-down.
Afternoon Heat And Weekend Shift
Under full sun, the valley is headed for the mid to upper 100s today, with southeasterly breezes turning gusty as the day wears on. Over the weekend, the pattern flips as a Pacific trough swings in and cranks up stronger southwest winds.
The National Weather Service has issued a Fire Weather Watch for parts of southern Nevada and northwestern Arizona on Saturday, June 6, 2026, when southwest winds of 20 to 25 mph with gusts near 35 mph and very low humidity, from the single digits to the mid teens, are expected, according to NWS Las Vegas. That combination of gusty wind, parched air and ready-to-burn fuels could allow any spark to spread quickly in exposed areas.
Where To Cool Off
Clark County has activated daytime cooling stations for June 4-5, 2026, at recreation centers, libraries and community centers across the valley. Many locations are open during daytime hours, and some sites are pet-friendly. You can find the full list of locations and details on the county website at Clark County, or call individual facilities to confirm exact hours.
What To Do
Drink plenty of water, skip or scale back outdoor activities during the hottest part of the afternoon, and check in on neighbors who do not have reliable air conditioning. Secure loose patio furniture before the winds pick up and hold off on any open-flame activities on Saturday. If you spot smoke or an uncontained fire, report it immediately and follow official instructions from local authorities.
