Las Vegas started Sunday, under clear skies and mild early-morning chill, with a local observing station clocking about 43°F (6°C) at 5:40 a.m. PST. From there, the city is on a straight glide path into a bright, sunny afternoon high near 72°F, with light east winds keeping things comfortable for anyone heading outside, as reported by the National Weather Service.
Afternoon Temperatures Climb
Afternoon highs will stay in the low-to-mid 70s through midweek, topping out near 75°F on Monday, February 2, 2026, and holding close to that through Wednesday, February 4. According to the National Weather Service Las Vegas, a ridge over the Southwest will keep conditions warm and dry and push temperatures about 10 to 15 degrees above what is typical for early February.
River Valley Gusts May Affect Boaters
The one wrinkle in this otherwise mellow setup is stronger north winds in the Colorado River Valley on Tuesday and Wednesday afternoons (February 3 to 4). Those gusts could kick up waves of 1 to 3 feet on Lake Mohave and Lake Havasu. Boaters should secure small craft and be ready for choppy water; we first flagged the river gust threat in our earlier warm-up preview.
What This Means For Your Plans
Afternoons will feel almost springlike, while mornings and nights slip into the upper 40s. A light jacket should cover the early starts and late finishes. If you are heading for the river or nearby lakes on Tuesday or Wednesday, keep an eye on the latest forecast before launching.
