Las Vegas rolled into Monday already warm, starting near 78°F and heating up to about 107°F by late afternoon, the first act in a week-long blast of desert heat. From Tuesday through Thursday, afternoon temperatures are expected to push up around 110°F, with only modest overnight cooldowns for anyone trying to get by without solid air conditioning.
What To Expect This Week
Skies stay mostly sunny, with highs near 107°F on Monday and around 110°F Tuesday through Thursday. Nights will be sticky and warm, with lows holding in the upper 70s to mid-80s. East-southeast winds will occasionally kick up, gusting into the low 20s mph Monday and in the 20 to 23 mph range by midweek. Those winds are forecast to strengthen again Friday and Saturday, which will bump up fire danger. A slight chance of isolated mountain showers or thunderstorms creeps in late Tuesday night into Wednesday as monsoonal moisture drifts north. Any storms that do pop up should be brief and scattered but could trigger dry lightning and gusty outflow winds, according to the National Weather Service Las Vegas.
Cooling Stations And Heat Safety
To help people ride out the heat, Clark County has daytime cooling stations operating across the valley from June 22–28 for anyone who needs an air-conditioned break. Locations and hours are listed on the county site. If your air conditioning cuts out or the power goes down, head to a cooling site, drink plenty of water, and skip outdoor exertion during the hottest part of the day. With very dry, gusty winds expected to return Friday and Saturday, officials are also asking residents to hold off on any activity that might throw off sparks or open flames.
Practical Tips
Whenever possible, move outdoor chores and work to the early morning hours, dress in light, breathable clothing, and check in on older neighbors and anyone who may not have reliable cooling. If you spot smoke or signs of fire, call 911 right away and get yourself to a safe, cool place.
