The month of August is coming to a close but the extreme heat is refusing to go away.
Southern Nevada is under an extreme heat warning until 8 p.m. Friday. Expect “dangerously hot conditions” this week, with temperatures between 108 and 112 degrees in the valley, the National Weather Service said. The normal high for late August is 102.
The alert was issued Monday morning, about 12 hours after another extreme heat warning expired.
This week’s warning is the fourth in the past month. The summer’s first extreme heat warning lasted from July 23 through July 27. The second started July 30 and was extended several times, finally expiring Aug. 9.
Cooling stations
Clark County has activated cooling stations at community centers, libraries and other buildings across the valley through Wednesday.
The cooling stations’ hours vary depending on the location. The stations include several locations in Las Vegas, North Las Vegas, and Henderson.
The stations are open to anyone in need of respite from the heat, the county said. Additional information can be found at the Southern Nevada Homelessness Continuum of Care’s website at helphopehome.org/get-help/.
Weak monsoon season
The monsoon season, which began in late June and lasts through September, has been almost nonexistent for the valley during a very dry year. However, on Monday, a storm inundated some neighborhoods in Henderson; one area received 0.55 inches.
Harry Reid International Airport has recorded 0.18 inches of rain this month, its wettest month since February (0.35). But the August average is 0.32. Reid has registered 0.69 inches of precipitation so far in 2026 (average through mid-August is 2.64).
Reid saw no measurable rain in July and very little in June. On June 23, the airport recorded 0.02 inches of rain, breaking a rainless streak of 124 days. It was the only rainfall of the month.
