Las Vegas wakes up under clear skies on Tuesday, May 12, 2026, already warming through the mid-70s and headed for a serious afternoon scorch. Forecasts call for a high near 105°F later today with only modest relief after dark, as overnight lows hover in the mid-70s. If you can, shift outdoor plans to the morning or evening and stick to air-conditioned spots when the heat peaks.
Afternoon Heat And Gusty Winds
Under sunny skies, temperatures are expected to climb into the low 100s this afternoon, topping out near 105°F. East-southeast winds of 2–18 mph will pick up and turn gusty, with gusts around 25 mph possible in more exposed areas. Those bursts of wind can jostle lightweight outdoor items and make any outdoor labor feel even more punishing. The National Weather Service Las Vegas has the full forecast and detailed heat-risk outlook.
Tonight And The Week Ahead
Tuesday night stays warm, with temperatures only dipping to around 75°F. The ridge overhead will weaken later this week, allowing highs to drop into the upper 90s on Wednesday and Thursday before another warm day Friday. Breezy afternoons may continue into the weekend as a trough noses into the Great Basin, though readings will still run several degrees above normal. It is all part of the multi-day heat pattern first highlighted last Thursday in this searing multi-day heat blast coverage.
Where To Cool Off
Clark County maintains an updated roster of daytime cooling stations, including libraries, recreation centers and some shelters for residents who need a break from the heat. Many locations list operating hours and pet rules, so it is worth checking before you head out. Visit Clark County for the full list along with downloadable PDFs of sites and hours.
How To Stay Safe
Stay on top of your water intake, skip heavy exertion during the peak afternoon heat, and never leave children or pets in parked cars. If you have to work outside, take frequent breaks in the shade or in air conditioning and keep an eye out for signs of heat illness.
