What is the coldest and hottest temperature in Las Vegas?

well, I probably found some information. Las Vegas is located on the edge of the Nevada desert in the United States, surrounded by mountains ranging from 1 meters to 3 meters. Las Vegas has four distinct seasons. Summer is a typical desert climate, and the temperature at noon is often as high as 38゜, while the temperature at night is relatively cool. There are often thunderstorms and the temperature is above average. The overall climate in winter is mild and suitable, and the average temperature during the day is around 15゜. Despite the occasional very hot weather, spring and summer are still the most pleasant seasons. Las Vegas is rarely attacked by bad weather, and it is one of the regions with the lowest relative humidity in all big cities in China. Surrounded by deserts, it is as dry as Death Valley. Because of the lack of rain, the air will be dry, so it is best to prepare some moisturizing products.

Las Vegas is 16 hours behind Beijing.
