Las Vegas in September

There are a number of benefits to traveling to Las Vegas in September. But is this month really as good as most travelers say?

Finally, the extreme summer heat is gone and the weather starts cooling down a bit as September progresses. However, it’s important to know how to plan your daily activities, when it’s still very hot at times, what to wear, what to bring, and which might be the best week in September to visit.

That’s why our Vegas residents wrote this guide with all the essential tips you should know. Additionally, we visited Vegas three times in September.

Is September a Good Time?

Due to the warm yet comfortable conditions, September is a very good time to visit and one of the best months to explore Las Vegas. Especially from mid- to late September the weather is pleasant without extreme heat periods. It’s a great month for exploring the Strip and hitting the pools.

September Tour Tips

The Mojave, Red Rock Sign, 7 Magic Mountains Tour (see the stunning photo) takes five hours and starts in the morning. That makes it perfect, even for early September when the heat is more intense in the early afternoon. We highly recommend this tour.

Special Tip: We know, this one is expensive, but it’s a spectacular once-in-a-lifetime experience. Please book in advance if possible:

The weather in Vegas during September is hot and enjoyable. As the month progresses the temperature cools off but is still very warm.

Average high temperatures in Las Vegas range from 99°F (37°C) in early September to 89°F (32°C) later in the month. In the first week, it’s possible that the temperature exceeds 100°F every day, and the chance of rain is higher. The average rainfall is 0.27 inches.

In our opinion, this is the perfect month for a Vegas trip. We visit each year in mid-September and the temperature is mostly between 90°F and 95°F in the afternoon. We like to spend our middays at the pool. 

Early September: Plan for summer-like conditions during the first week of the month and try to avoid the midday and early afternoon sun. Historically, visitors can still count on about 100°F during the day and around 80°F at night.

Mid-/Late September: However, as the month progresses the weather cools down and temperatures drop to around 95°F and finally to 89°F. If you enjoy warm weather but dislike intense heat, the last two weeks are the perfect time to visit.

Typical temperature progression during the month of September:

  • Early September: 99°F (37°C)
  • Mid-September: 95°F (35°C)
  • Late September: 89°F (32°C)

The humidity hovers around 25% and there are an average of 12 hours of sunlight per day. Mornings before and after sunrise and late evenings are the coolest part of the day in Vegas during September. The afternoons are still hot with high temperatures and low humidity. Find below a typical temperature progression during a day

  • Early (8:00 AM): 77°F
  • Afternoon (1:00 PM): 91°F
  • Evening (9:00 PM): 85°F

Further below in this article, you can find detailed tips about our recommended activities in the morning, afternoon, and evening. 

Is it Cold in September?

Las Vegas is not cold in September. The weather is still hot in the first two weeks of September, with summer-like temperatures reaching the mid-90s, often breaking 100°F. Mornings and evenings are cooler than in previous months.

Coldest Temperature

The coldest average low temperature in early September in Vegas hovers around 75°F in the first half and about 65°F towards the end of the month during nighttime. The coolest part of the day will be between 10 PAM and 10 AM.


The average humidity in Vegas during September is around 25%. Mornings in Vegas during September are cooler and less humid, with humidity climbing as the day gets hotter. The evenings begin to cool down again and the humidity drops.

Rainfall / Monsoon

The average rainfall in Vegas during September is 0.27 inches (7mm). The city is expected to have around 3 days of rainfall over the whole month.

The probability of rain falling during September is at around 10% at the beginning of the month, dropping down to 7% percent by the end of the month. Early September is at the end of the Monsoon season, that’s why the chance of rain is higher compared to the rest of the months.

What to Wear / What to Pack

During September in Las Vegas, you should wear light layers, shorts, and t-shirts. The weather is still very hot during the day so pack light clothing. The pools are open so don’t forget your swimsuit. However, mornings and evenings are cooler so wear a light sweater or cardigan at these times.

The temperatures at the beginning of September in Vegas are much hotter than at the end of the month, so bear this in mind when you are packing for your trip. You will still need sunhats, sunglasses, suncream, and a refillable water bottle during September as daytime temperatures reach the mid-90s.

When we visited Vegas in September for the first time, we didn’t follow these rules. Eventually, one of us got dehydrated, and another one got sunstroke.  That’s not what you want while on vacation.

Visiting nightclubs: Keep in mind, that most nightclubs do have a dress code, so come prepared to dress to impress.

Visiting casinos and shows: There is no official dress code for visiting casinos and shows in Vegas, however, if you are visiting during the evening it is advisable to dress smartly. For women, a dress or smart trousers, and a dressy top are good choices. For men, a smart button-down shirt and smart pants (trousers) with dress shoes are expected.

💡 For our September visits, we always brought one or two light sweaters. When going to the casinos, the air conditioning can feel especially cold compared to the outdoors.

  • Light trousers or leggings

Pool Time / Open Pools

During September the pools in Las Vegas are open and it’s a fantastic month to visit them. Within the first week the best time of day is in the morning and the late afternoon as it’s still very hot around noon. As the month progresses, even middays are great for hitting the pool.

Regardless of when you go, stay hydrated, use lots of sun lotion and wear hats while lounging.

Pools are typically open between 8 AM and 7 PM. Please find below the most popular hotels and their pool opening hours (subject to change):

  • The Bellagio: 9 AM – 5 PM
  • Caesars Palace: 10 AM – 5 PM
  • The Aria: 9 AM – 5 PM
  • The Cosmopolitan: 8 AM -6 PM
  • Mandala Bay: 9 AM – 5 PM (depending on the pool)

Pools with umbrellas help to stay cool, especially in early September. Cabanas, though expensive to rent, offer the most shade and comfort. Please keep in mind, that you can or have to reserve seating, daybeds, or cabanas (sometimes for registered hotel guests only).

Crowds and Hotel Rates | Deals

The famous Flamingo Hotel & Casino. Its location is perfect on The Strip. Check details and visitor reviews here: Flamingo via (low price deals)

In September over 3.4 million visitors come to Las Vegas. Weekends are busier than during the week. Especially Labor Day weekend will be sure to attract more people and therefore raise hotel rates during this time. The cheaper times to book are weekdays Monday to Thursday.

Find Las Vegas hotel deals via via this link: Las Vegas Hotel Deals (Tip: Sort by start rating and price!). We always use as we find the best deals there, but you are free to use any other hotel website of course!

The “Life is Beautiful” music festival usually takes place over a weekend in downtown Vegas during September which increases crowds and rates.

Things to Do in the Mornings / Afternoon / Evenings


Mornings during September in Vegas are the perfect time to explore outside areas.

If you’re interested in hiking or climbing in the nearby Red Rock Canyon National Conservation Area, make sure to get there early, bring lots of water, and protect yourself from the sun. Ideally, you want to be done before noon. (Also, be prepared to pay the entrance fee in cash.)


Since afternoons are still so warm, even towards the end of the month, it’s the perfect time to lounge poolside. If you are looking for a party atmosphere, there are plenty of dayclubs around Vegas with resident DJs blasting music.

If you are staying at the hotel, some clubs will allow entry without a fee, however many will charge a cover fee or request that you rent a cabana for the afternoon. Many of the dayclubs have offers on alcoholic drinks to promote the club, but remember to always stay hydrated with water during the day.

Quite often, we didn’t feel that hot in September, but it’s easy to get dehydrated especially if you are enjoying a drink or two.

If you would prefer a more relaxed pool experience, there are plenty of pools that have a more relaxed vibe. Look for hotels that have more than one pool, as usually, at least one of the pools will not have DJs playing and will have a quieter, relaxing atmosphere.

Hotels such as the Aria and the Cosmopolitan have quieter day pools.


This is the time of day you can enjoy walking the strip without having the sun beating down on you. It will still be pretty warm, but you won’t run the risk of overheating.

Vegas is known for its nightclubs, and world-renowned live shows and restaurants. Make sure to bring clothes that make you feel good and that you want to be seen in.

From our experience, you can wear the most outrageous outfit and fit right in! This includes jewelry and accessories too.

Grand Canyon/Hoover Dam Tour

A tour of the Grand Canyon and Hoover Dam in September is a welcome change of scenery from the typical Vegas activities. A full-day tour (11-12 hours) features the sights of the West Rim. You will be driven through Joshua Tree Forest and lead you on a hike to Guano Point, among other natural attractions. We recommend this in late September when it’s the temperatures are more pleasant.

Area15 (Near Las Vegas Strip)

Area15, an indoor attraction just minutes from the Las Vegas Strip, provides larger-than-life art installations, virtual reality experiences, unusual and intriguing experiences, and events. It’s similar to a shopping mall, except instead of the usual stores, you’ll find artists and unique things to interact with. As everything is air-conditioned, this is a must-visit if you want to cool down in early September!

The Neon Museum

This attraction was built in the 1930s, and there are now over 200 neon signs on the spacious property.

The Neon Museum is a great activity but as it’s outside we don’t recommend a visit in early September during midday or the afternoon heat.
