Although you can expect cooler weather in Las Vegas in September, it’s still hot during the day and much more pleasant at night. When the temps get back to the 90s, locals get excited that fall is coming. However, we know that heat waves can still hit.
You’ll want to avoid being outside in the middle of the day by sticking with indoor activities or staying poolside. Sunrise and sunsets are good for outdoor activities. See what to pack below.
Additionally, most schools have started, so you should see hotel rates start to drop (although post-pandemic may look different).
