Las Vegas is starting Tuesday, February 24, 2026, on a bright and comfortable note, with morning readings in the upper 40s and plenty of sunshine in the mix. Afternoon highs are expected to climb near 75°F, then jump into the low 80s by Wednesday and reach the mid 80s by the weekend.
Hot Week Ahead
A broad ridge of high pressure parked over the Southwest will send temperatures running well above normal through the week. The National Weather Service is calling for a Minor (Level 1) HeatRisk across the lower Mojave valleys later this week, which means some people, especially older adults, infants and those without reliable cooling, could be caught off guard, according to NWS Las Vegas. Expect light breezes in the valley during the day and overnight lows only dropping into the mid 50s to upper 50s, so the cooler hours are not going to feel especially cool.
Heat Safety And Local Resources
To handle the warmth, try to schedule strenuous outdoor chores or workouts for the early morning or later evening, drink plenty of water, and check in on seniors and pets during the hotter parts of the afternoon. Clark County and community partners open daytime cooling stations when excessive heat is declared; residents can call 2-1-1 or check county information for locations and hours, per Clark County. If you have an outdoor gathering planned this weekend, make sure you have shade, water and a simple plan to cool people down if temperatures spike more than expected.
Winds And Mountain Chances
Forecasters are also watching gusty westerly winds that are expected to develop across the western Mojave Desert today and Wednesday, with the strongest gusts focused over higher terrain rather than the Las Vegas Valley. There is a small chance of light precipitation in the high Sierra today and tonight, but snow levels will stay above 10,000 feet, so valley travel should remain dry. If you are headed for the mountains or planning a trip along the river corridor later this week, keep an eye on updated forecasts and conditions.
