Las Vegas is starting Wednesday with temperatures in the mid-50s around daybreak. The forecast calls for a sunny afternoon topping out near 75 degrees.
Gustier Stretch Arrives Thursday
Thursday brings more sunshine and a high near 79 degrees, with gusts forecast at 20 to 30 knots. Stronger winds are expected overnight Thursday.
The National Weather Service says a Wind Advisory is in effect from Thursday morning through Friday morning for the lower Colorado River Valley, southern Clark County, the Mojave National Preserve and the Cadiz Basin, where gusts could reach 40 to 50 mph. Drivers on exposed routes should use caution, and residents may want to secure loose outdoor items before the stronger winds arrive.
Wind Advisories and Local Conditions
The advisory described here forecasts gusts of 40 to 50 mph in the named areas; that range is not presented as a universal advisory threshold. The National Weather Service Las Vegas notes that valley topography contributes to local wind variations. Its 2025 climate summary lists a highest gust of 65 mph on 09/26, a past observation distinct from this week's forecast.
For driving in high winds, the National Weather Service Weather-Ready Nation advises slowing down, holding the steering wheel with both hands and leaving extra distance from high-profile vehicles.
Warm, Dry Weekend Outlook
Friday will be sunny with a high near 82 degrees, followed by highs in the 80s Saturday and temperatures in the 70s Sunday. Monday looks warmer still, with a sunny high near 83 and only light winds expected.
Showers and thunderstorms could continue through Tuesday.
