Although you can expect colder weather in Las Vegas in September, it is still hot during the day and much more pleasant at night. When the time goes back to the 90s, the locals are excited that autumn is coming. However, we know that heat waves can still strike.
Do you want to avoid staying outside in the middle of the day by holding on indoor activities or stay by the pool. Please note that during the weekend for Remembrance Day (September 3-6), the pools will fill up.
Sunrises and sunsets are good for outdoor activities, such as hiking, climbing, boating on Lake Las Vegas or Lake Mead.
In addition, most schools have started, so you should see hotel prices start to fall (although a post-pandemic may look different).
