Las Vegas eased into Thursday with classic desert calm: clear skies, dry air and light breezes at Harry Reid International, where temperatures hovered around 64°F early in the morning. That brief comfort window will not last. The city is on track to jump into the low 90s on Thursday, then keep climbing into the upper 90s and eventually triple digits by the weekend and early next week. Forecasters expect the most intense heat on Monday and Tuesday, with warm nights offering little relief. If you have outdoor plans, try to front-load the hard work into the morning or save it for the evening, and know in advance where you can cool off.
What To Expect This Week
Forecast highs are set to climb fast, from about 93°F on Thursday, May 7, 2026 to roughly 99°F on Friday, May 8, 2026. Temperatures are projected to top out near 100°F on both Saturday and Sunday, then surge to around 104–105°F on Monday, May 11, 2026 and Tuesday, May 12, 2026. The National Weather Service estimates about a 50% chance of hitting 100°F on Sunday, with the mark becoming almost a lock on Monday and Tuesday. Most valley neighborhoods should see light winds, although some exposed spots could get gusty in the afternoons. These details come from NWS Las Vegas.
Heat Risk And Who's Most Affected
As temperatures spike, overall heat risk across the valley is expected to climb from Minor or Moderate this weekend to locally Major in the hottest neighborhoods early next week. Older adults, people living with chronic health conditions, outdoor workers and anyone without steady access to air conditioning are most at risk, especially with nighttime lows stuck in the low 70s that will not offer much cooldown. Drink water regularly, take frequent breaks in shade or air-conditioned spaces and do not leave children or pets in parked cars, even for a short errand. If your job keeps you outside, try to schedule the heaviest tasks for before 10 a.m. or after 6 p.m.
Cooling Stations And Local Resources
Clark County keeps an updated list of daytime cooling stations and other community resources for residents who need a safe place to ride out the hottest hours. For specific locations and hours, check the county's cooling-station page, and see how desert heat lurks behind the winds for added context and practical tips. Visit Clark County cooling stations for the complete list and downloadable PDF of sites.
Plan Ahead
Expect hotter afternoons to stick around through at least midweek, and check the forecast before committing to outdoor events. Near-record highs are possible on Monday, May 11, 2026 and Tuesday, May 12, 2026, so build in extra time and shade if you will be outside. Keep a water bottle handy, seek out trees or awnings whenever you can and check on neighbors who might struggle with the heat.
