Clear skies and very dry air hang over the Las Vegas Valley this morning, with readings near 79°F at Harry Reid International and relative humidity in the low 20s. Temperatures are set to spike today, with a high near 108°F on Friday, June 12, 2026, and triple-digit heat expected to stick around through the weekend and into next week.
Today Through Next Week
Friday stays sunny and hot with a high near 108°F and light southeast winds around 2 to 10 mph, with some afternoon gusts into the teens in a few spots. Friday night will not cool off much, with lows holding near 82 to 84°F. A modest bump in moisture this weekend brings a slight chance of high-based showers or an isolated thunderstorm over the higher terrain. Forecasters say major to extreme heat risk ramps up Monday, June 15 through Thursday, June 18, 2026, with valley highs pushing 110 to 111°F and the hottest lower desert locations running even warmer. Overnight lows in the low 80s will offer little break from the heat, raising concerns about heat stress, according to the NWS Las Vegas.
Impacts And Where To Find Relief
Hot days paired with warm nights increase the risk of heat illness for outdoor workers, older adults and anyone without solid air conditioning. Drink water often, take frequent breaks and stay out of the midday sun as much as possible. Clark County and health partners run cooling-station activations and hydration outreach. Call 2-1-1 or check local listings for daytime cooling sites and services, per Clark County.

Plan Ahead
If you have outdoor plans, try to move them to the early morning or evening, and make a cooling plan for children, elders and pets. Keep tabs on forecast updates and local alerts, and call 2-1-1 if you need help finding a nearby cooling option.
