Las Vegas woke up Monday, May 4, 2026, to clear skies and mild desert air, with local observation sites reporting around 64°F. Breezy southwest winds will ramp up through the day and keep highs near 79°F, about 8-12 degrees cooler than the weekend peaks.
Afternoon Winds Pick Up
South-southwest winds will strengthen from mid-morning into the afternoon, with sustained speeds around 12-21 mph and gusts expected to reach up to 29 mph later today. The strongest gusts are likely during the mid- to late-afternoon window, which could make biking a slog and send any unsecured patio furniture on a short tour of the neighborhood.
Spotty showers and isolated thunderstorms should stay mainly over higher terrain, while the Las Vegas Valley itself remains mostly dry. According to the National Weather Service, winds should ease overnight but remain on the breezy side into Tuesday as the low-pressure system moves through the region.
Mountain Showers, Not Valley Flooding
Scattered showers and isolated thunderstorms are most likely over the higher ranges in northern Inyo, Esmeralda and central Nye counties, with any rain in the Las Vegas Valley expected to be light and brief. Where storms do develop, they could bring brief heavy downpours and erratic, gusty winds, so localized impacts near the foothills are possible.

Late-Week Heat Risk
High pressure ridging builds back in later this week, sending temperatures into the upper 80s and 90s by Thursday and into the weekend. The National Weather Service highlights a Moderate (Level 2) heat risk for desert valleys from Friday through Sunday.
Las Vegas currently has about a 15% chance of hitting 100°F on Saturday and a 40% chance on Sunday. For heat-safety tips and local cooling-station information, see the Southern Nevada Health District Beat The Heat resources.
What To Do
Before the gusts kick up, secure loose outdoor furniture and tie down canopies. If you will be outside, carry water and try to schedule strenuous activity for the cooler hours of the day. Keep an eye on the National Weather Service forecast and local public-safety pages for any advisories if the winds or upcoming heat trend stronger than expected.
