While summer is coming to an end in other parts of the country, September in Las Vegas is still hot and the days are still long. However, with kids back in school, the swimming pools tend to feel a lot more spacious and less noisy. This time of year also sees the return of sports with NHL hockey preseason at the T-mobile Arena and the sportsbooks—rooms for watching and betting on sports—getting really lively with the return of college football and the beginning of baseball playoffs.

September Weather in Las Vegas

It may be cooling down a bit, but Las Vegas is still extremely hot and dry in September. Over the whole month, the average temperature is approximately 86 degrees Fahrenheit (30 degrees Celsius), but this does fluctuate as time goes on. In the early part of the month, high temperatures can reach 95 degrees Fahrenheit (35 degrees Celsius) but drop as low as 66 degrees Fahrenheit (19 degrees Celsius) in the evening. By the end of the month, the average highs are closer to 80 degrees Fahrenheit (27 degrees Celsius).

  • Average high: 94 degrees Fahrenheit (34 degrees Celsius)
  • Average low: 71 degrees Fahrenheit (22 degrees Celsius)

Since the city is in the desert, the humidity will remain low most of the year, including September. Rain is not impossible, but the likelihood of it stands at around 10 percent in September.

What to Pack

When packing for Las Vegas, you'll need to prepare your suitcase with your summer attire for the high daytime temperatures and fall staples for the cooler evenings. Considering also that the casinos regularly have the air-conditioning on full-blast at all times of the year, a light sweater and a pair of long pants are must-haves. If you hope to do some sightseeing or traveling to some of the nearby parks, make sure you have comfortable close-toed shoes and if you plan on lounging by the hotel pool, don't forget your bathing suit.

September Travel Tips

  • The pools in Vegas are legendary, and the crowds at the pool have thinned out some by September, making your plight to find a lounge chair easier. It’s still plenty warm but no longer oppressive oven-like heat. Late afternoons are extremely satisfying at the pool and they get you going for an early dinner or a late night at the clubs.
  • In September, you can walk around before noon without getting too hot, but the best time to go out for a stroll on the Strip is around 5 p.m. The sun doesn't usually set until 6 or 7 p.m.
  • If you're a golfer, midweek rounds are perfect since the oppressive heat of August has usually died down by now. It can still be hot on the course, but the temperatures are becoming more moderate.
  • The Grand Canyon is a 250-mile drive from Las Vegas and it takes about four hours to get there. If you want to spend less time in a car, but want to see some amazing canyons and picturesque views, go to Zion National Park instead, which is about three hours away.
