Weather overview for Las Vegas , Nevada 

When planning a Las Vegas holiday, your budget might be the first thing that you consider, but you also need to think about what time of year you want to visit. The weather varies greatly throughout the year in Las Vegas the winter months are dry and cold with short days and long nights, whilst the summer months are blisteringly hot with long days and short nights.


Las Vegas is located in Nevada in the Mojave Desert. Thanks to its location, the city experiences an arid desert climate which means there is hardly any rainfall at all even during the winter months. The wettest month of the year in Las Vegas is usually August, when the city is subject to 14mm of rainfall which is divided between six rainy days.

Of the tiny amount of precipitation received by Las Vegas, 58% of it is light rain, 20% is thunderstorms, 17% is moderate rain, 3% is heavy rain and 2% is light snow.

Average Sunshine Hours

Las Vegas typically enjoys 292 days of sunshine each year, 210 of which are classed as sunny days and 82 of which are classed as partly sunny days. January 28th is often the cloudiest day of the year and March 30th is usually the clearest day of the year, although with median cloud coverage of 0% over the course of the year, every day is pretty clear in Las Vegas.

The shortest day of the year is December 21st, with only 9:42 hours of sunlight, whilst the longest day of the year is June 20th, with 14:38 hours of daylight.


Late autumn and early spring are the best times of the year to visit Las Vegas, when the average temperatures are pleasantly warm. Since this is when the city enjoys its best weather, these times are also incredibly popular for holidaymakers to visit, which often results in sky-high flight and accommodation prices.

Although it's cold by Las Vegas standards, winter in the city is mild compared to winter in the UK, making December to February a great time to escape the UK winter weather and take a cheap trip to Las Vegas.

If you want to snap up a deal on flights and accommodation, your best bet is to visit during the summer months that's when hotel and flight prices will usually be at their cheapest. Don't forget that the money you save on accommodation and travel will need to be spent on protective clothing and suntan cream, since the weather in Las Vegas at this time of year is incredibly hot and sunny.

Summer Weather in Las Vegas


Summer in Las Vegas is dry, hot and long, as you'd imagine for a city located in the middle of the desert. If you choose to leave the comfort of the air-conditioned hotels and casinos between June and August you will be met with the unyielding Mojave Desert sun which sees Nevada reaching temperatures in excess of 40°C on a regular basis.
