Las Vegas woke up to clear, mild weather on Wednesday morning, March 11, 2026, with temperatures sitting in the mid-60s under bright, dry skies. The valley is expected to climb into the upper 70s this afternoon, likely the last truly comfortable day before a sharp warm-up takes hold. If you have outdoor plans, this is the time to shift them to morning or evening as daytime highs ramp up later in the week.
What To Expect This Week
According to NWS Las Vegas, temperatures will rise steadily over the next several days: a high near 79°F on Wednesday, about 85°F on Thursday, upper 80s on Friday and near 90°F on Saturday, with the potential to reach the mid-90s by Tuesday, March 17, 2026. There is virtually no chance for rain and winds should remain light across the valley, although northerly breezes may pick up in the Colorado River Valley on Thursday. Daily temperatures are expected to run roughly 15–20°F above normal for this time of year.
Heat Impacts And Safety
Forecasters have flagged a Minor-to-Moderate heat risk for southern Nevada, with the biggest impacts expected for people without reliable cooling, older adults and visitors who are not accustomed to desert heat. Clark County is reminding residents about cooling stations and safety tips; call 2-1-1 for locations. Officials recommend staying hydrated, avoiding midday errands and checking on neighbors who may need help. Employers and outdoor crews are urged to plan extra breaks, shade and water, and parents are advised to be cautious about hot playground surfaces.
Commuters And Outdoor Plans
Pavement and playground equipment will heat up quickly in the afternoon sun, so limit direct exposure for children and pets and never leave anyone in parked cars. If you will be outside, try to shift activities to early morning or evening, carry plenty of water and wear sunscreen and light clothing. Pool days and shaded patios are likely to be in high demand as the heat builds, and residents should plan for warm evenings as overnight lows remain unseasonably high.
