Las Vegas woke up under clear skies and low 80s on Wednesday morning, June 17, 2026, and the desert broiler is flipping back to high. Forecasters are calling for afternoon highs near 110°F, with the most intense heat arriving in the late afternoon and early evening. Overnight relief will be limited, with lows stuck in the mid‑80s across much of the valley.
Afternoon Heat
Skies stay sunny all day, with south-southwest winds around 5 to 15 mph and afternoon gusts up to about 23 mph, which will only add to the brutal feel, according to NWS Las Vegas. Temperatures will ramp up quickly after midmorning before peaking late in the day, so outdoor work is safest in the early morning or later in the evening. The heat will hit hardest for outdoor workers, older adults and anyone without dependable air conditioning.
Where To Cool Off
Clark County has opened daytime cooling stations across the valley, including libraries, recreation centers and shelters, with several locations operating through Wednesday, the county reports. The county’s cooling-stations page lists locations and hours, along with 24-hour options for people experiencing homelessness, according to Clark County. If you rely on AC at home, the advice is simple: do not wait until it fails. Get to a cooling site or any public air-conditioned building before the heat catches up with you.
Friday Winds And Fire Danger
A shortwave moving into the region will ease daytime highs slightly by the weekend, but it will also ramp up southwest winds on Friday, June 19, 2026. The National Weather Service notes the western Mojave near Barstow could see gusts nearing 40 mph. Combined with very low humidity and dry fuels, those winds will bring elevated fire danger to parts of the region Friday afternoon and evening. Drivers should also watch for roadside dust and blowing debris in wind corridors and give extra room to cyclists and smaller vehicles.
Drink plenty of water, skip strenuous outdoor activity from late morning through early evening, and check in on neighbors, pets and anyone who may struggle to keep their home cool. Employers should provide shade and frequent water breaks for outdoor crews, and anyone who loses AC should head to a cooling station or another air-conditioned public space. For up-to-date conditions and any changes to cooling-site options, keep an eye on local forecasts and county announcements.
