Vegas Temperature Trends - Celsius

As the graph shows, the Las Vegas Weather isn't always warm, although it's rarely very cold. Normally the low temperature in Las Vegas on any given day will be around 15 degrees cooler than the daily high. It's not unusual for the temperature in Las Vegas to be cold when you wake up, and two hours later for it to fell much warmer outside. You may want to layer your clothing in between late fall and early spring if you leave your hotel room early.

High temperatures are regularly more than 10°C higher than the lows, and the difference can feel like even more because of the intense desert sun. The difference between the way people feel warmth in the shade versus in the sun is more pronounced in Las Vegas' normally dry weather than it is in more humid climate because humidity tends to transmit warmth more evenly.

The heat in the middle of the day in the middle of summer will make outdoor activities that don't involve getting wet uncomfortable, even impossible at times. Golf courses often lower their afternoon rates in July and August. But even in the hottest months the early morning is usually pleasant.
