LAS VEGAS, NV – The desert city wakes under clear skies and calm air, the Strip’s skyline glowing in crisp morning light. Early December arrives quietly in southern Nevada — a tranquil stretch of mild weather before cooler changes move in later this week.
The National Weather Service in Las Vegas reports highs in the low 60s through Tuesday, with nights cooling into the upper 30s to low 40s under mostly clear skies. Winds stay light and variable — ideal for holiday travelers, outdoor shows, and early-December events across the valley.
By Wednesday, however, subtle shifts in the upper atmosphere will bring a dip in daytime highs to the upper 50s, a few degrees below average for early December. While no rain or snow is expected, desert chill returns at night, and outlying areas near Red Rock Canyon and the Spring Mountains could briefly flirt with the upper 30s after sunset.
Residents and visitors should expect perfect outdoor conditions through midweek — bright sun, light winds, and low humidity. But with a high-pressure ridge flattening by Thursday, meteorologists hint at a cooler, breezier pattern into next weekend — a possible early signal of the season’s first true December cold snap across the Mojave.
