What to expect from the Las Vegas weather in September
In many ways, September is the ideal ‘best of both worlds’ time of the year in terms of Las Vegas weather.
Those who love the sun and hot temperatures will still enjoy it, and those who don’t will be able to cope with it.
For all many, myself included, love the searing temperatures of July and August, they are not ideal for exploring the Strip. There is no such problem in September. Well, not for most days anyway. It’s usually cooler. Not so much to make you lose out, but just enough to become more manageable.
For sunbathers, the pools tend to be a little less packed in September too. So, for all you trade a few degrees, you gain in comfort.

How likely is it to rain in Las Vegas in September?
September is not known as a rainy season in Vegas at all. There will be some scattered showers now and again, but that is about it
The start of the month is still monsoon season, or as close to Vegas gets to it. There might be the odd heavy downpour left over from August. They pass quickly, though, and they are quite spectacular to watch. You go to Las Vegas for spectacular.
Generally, though, you can expect, on average, three rainfall days during September.

Las Vegas is in the desert, so humidity is never really going to be a problem. For me personally, that is a big part of what makes the weather so good there.
It’s a very dry heat generally, and it’s very rare that the humidity climbs above 66% across the course of the whole year.
There might be some mild humidity around in Vegas during September, but mild is as bad as it will get. As a general rule expect the air to be dry.
What to pack for Las Vegas in July
You will only really need your summer clothes if you’re visiting Vegas in September. Most wear shorts and t-shirts during the day.
The evenings and nights are still warm too, so you can leave those jackets at home.
You might want to chuck an emergency hoodie into your suitcase, but I’d be surprised if you’ll need it. The pools are still open in September too, so don’t forget your swimwear.
One of the issues that does often come up in the dry heat is dry skin or lips. That’s why it’s often recommended to pack a lip balm/chapstick. Don’t worry if you don’t though, almost every gift shop or convenience store have them to purchase.
