Las Vegas started the day under clear skies and temperatures already running warm, as the weekend heat swells to a peak today and Tuesday with highs near 105°F across the valley. Triple-digit afternoons are expected to stick around through Tuesday before a modest cooldown creeps in by midweek.
What To Expect
Sunny skies and a high near 105°F are on tap Monday and again Tuesday, with valley temperatures popping above 100°F by early afternoon and peaking mid-to-late day. Overnight lows will only slip into the low 70s, so the desert nights will not offer much of a breather. This multi-day stretch and the associated heat risk are outlined by the National Weather Service, according to NWS Las Vegas.
Heat Safety And Cooling Centers
Clark County has opened daytime cooling stations for residents who need an air-conditioned break from the heat, with hours and locations varying by site. Officials urge people to check local listings before heading out and to prioritize hydration and shade, especially for vulnerable neighbors and pets. Current cooling station details and guidance are available through Clark County.
Afternoon Winds Could Add Impact
Southwesterly winds are expected to ramp up from midday into the afternoon, with sustained speeds often 10 to 65 mph and gusts to 20 to 65 mph across the valley; gusts could reach 25 to 60 mph in parts of the western Mojave. Those stronger bursts may kick up dust, make outdoor events feel even hotter, and create intermittent gusty conditions at Harry Reid International Airport. The National Weather Service flags these breezy afternoons alongside the heat risk, according to NWS Las Vegas.
What You Can Do
Avoid strenuous outdoor activity during the hottest hours in mid-afternoon, drink plenty of water, and check on elderly neighbors or anyone without reliable air conditioning. Never leave pets or young children in cars and bring them inside where it is cooler; if you feel dizzy, confused, or faint, move to a cool place and seek medical help. For planned events or long outdoor shifts, shift schedules earlier in the morning or later in the evening when possible.
