Does It Rain in Las Vegas During December?
December remains very dry despite being winter. Las Vegas averages only about 0.5 inches (12 mm) of rainfall during the month, and rainy days are uncommon.
Snow on the Las Vegas Strip is extremely rare, although nearby mountains such as Mount Charleston often receive snowfall, creating beautiful scenic views just outside the city.
What to Pack for Las Vegas in December
Packing warm layers is essential for December.
During the day, long pants, comfortable walking shoes, and light sweaters are usually enough. After sunset, temperatures drop quickly, so bring a warm jacket, hoodie, scarf, or coat if you plan to spend time outdoors.
If you’re visiting for New Year’s Eve celebrations, remember that you’ll likely be standing outside for several hours, so dress much warmer than you normally would.
