Las Vegas is trading winter vibes for short sleeves on Monday, February 23, 2026, with clear sunshine and a high near 72°F. Light winds and low humidity should keep the afternoon feeling comfortable, even as temperatures are expected to climb through the rest of the week.
Week Ahead: Warm-Up Into the 80s
Highs are set to rise steadily, reaching around 75°F on Tuesday, near 79°F on Wednesday, and into the low 80s from Thursday through Saturday, with little chance of rain across the valley. A "Minor" HeatRisk has been flagged for desert valleys later in the week, and only slight precipitation chances are expected for the eastern Sierra peaks, according to NWS Las Vegas.
Plan Outdoor Activities
With an early-season warm-up on the way, it is a good time to shift strenuous outdoor activities to the mornings or evenings, carry water, and check on older relatives and pets as afternoons heat up. Clark County and community partners open daytime cooling stations when excessive-heat conditions are declared; residents can dial 2-1-1 or check county resources for locations and hours, according to Clark County.
Today: Clear and Dry
The valley stays dry and mostly sunny today, with afternoon temperatures peaking in the low 70s and overnight lows returning to the 40s while winds remain generally light. There are no active watches or warnings for the Las Vegas Valley at this time, though mountain areas could see brief high-elevation precipitation later in the week; check the full local forecast for details from NWS Las Vegas.
