Las Vegas Climate and Weather
If you’re planning on visiting Las Vegas (and let’s face it, why wouldn’t you?), it’s important to know what kind of weather may await you when you arrive.
In terms of classification, Las Vegas has a sub-tropical climate that is typical to the surrounding Mojave desert. Basically, it’s hot: the city basks in over 300 days of hot sunshine per year, and glories in over 3,000 hours of sunshine annually. Rain is rare, but when it happens it can be almost torrential; it only rains for around 29 days per year, but this can be heavy and stormy if caught in it.
Las Vegas weather is at its hottest during the summer months, typically July to September. Temperatures during this period reach highs of 94-104F/34-40C during the day, dipping to a still-balmy 69-78F/21-26C over night. If you are unused to a hot climate, it may be best to avoid Las Vegas at this time of year due to the unrelenting sunshine and high temperatures. However, it is worth considering the fact that the humidity is usually extremely low, which does make the temperature more bearable.
The winter months may provide some relief if the scorching temperatures of summer pose a problem. Winter with Las Vegas weather is generally mild, and while the surrounding mountains may see snowfall it rarely falls on the city itself. Temperatures during the day reach highs 60F/16C, with night time lows of 40F/4C. On occasion, temperatures can drop to freezing, though this is unusual.
Best Times To Visit
If you are planning a holiday to Las Vegas and the Las Vegas weather is a concern for you, the best time to visit is between March and May or October and November. The spring and autumn months provide a happy medium between the extreme temperature peaks and valleys of the summer and winter months.
In March, the temperature in Las Vegas weather reaches highs of 69F/20.5C, providing a comfortable visiting environment for most people. If you prefer a little more heat, April averages at 78F/25.5C, which coupled with sunshine should provide adequate sunbathing weather. Finally, May is the warmest of all of the spring months, with highs of 88F/31.1C.
On the latter end of the calendar, autumn offers similar temperatures. September reaches highs of 95F/35C, so still hot but not as punishing as the Las Vegas summer. Perhaps the best month of all is October, which reaches highs of 82F/27.7C, providing a happy medium between bearably hot and simply too hot. Adding in the lack of humidity that creates a dry heat with Las Vegas weather, October is arguably the most suitable time to visit. Lastly, consider November, which averages 67F/19.4C during the day, though may become chillier at night (42F/5.5C).
What To Pack
If you are packing your suitcase for your Las Vegas holiday, we recommend summer clothes of a sort, even if you are going in the coolest months. It may be worth taking a rain jacket, but considering the amount of Las Vegas that is underneath roofing and the usual lack of rainfall, it may be wasted space in your suitcase. If visiting in winter, light winter-suitable clothes will suffice; no need for thermals!
