Las Vegas starts off Saturday, May 9, under clear skies and comfortably in the 70s, but the city is headed for a serious heat jump. By this afternoon, temperatures are expected to rocket toward 100°F, with only modest cooling once the sun goes down.
How Hot And When
The heat ramps up through the holiday weekend and into early next week. Forecast highs are near 100°F on Saturday, May 9, around 101°F on Sunday, May 10, then peaking near 105°F on Monday, May 11, with Tuesday still holding in the low 100s. Those numbers run about 10 to 15 degrees above what is typical for this time of year, according to NWS Las Vegas.
Heat Risk And What To Do
Overnight lows stuck in the low 70s, paired with triple-digit afternoons, raise the risk of heat illness for older adults, outdoor workers, young children and pets. Health officials recommend limiting strenuous activity during the hottest part of the day, taking frequent water breaks and keeping an eye out for dizziness, nausea or confusion that can signal heat-related problems. Clark County maintains an updated list of daytime cooling stations and community resources for anyone who needs a cool place to be, and you can check Clark County for locations and hours.
Midweek Wind Watch
Forecasters also point to a shortwave tracking into the region by midweek that could kick up the wind. Southwest gusts of 20 to 30 mph are possible from Tuesday afternoon through Thursday, which may make outdoor work feel even tougher and send dust flying in exposed areas. If you have outside plans, secure loose items, plan extra time for errands and try to schedule the heaviest tasks for early morning or evening when conditions are a bit more forgiving.
