Light summer attire is recommended such as shorts, sandals, skirts, T-shirts, sundresses, and tank tops but keep in mind there are specific dress codes for casinos, restaurants, bars, and nightclubs. 

Don’t forget your sunscreen, sunglasses, and a good pair of walking shoes. 


Things to Do in Las Vegas in August

If you thought it was hot in July, August is likely to be even warmer, so this might not be the best time to take a free walking tour in Las Vegas.

Even so, some tourists may still want to consider this activity.

Anyone looking to beat the heat will have plenty of events to attend, as there are always dozens of great concerts to see in Las Vegas each month.

There are also a lot of great theatrical events such as Cirque du Soleil.

Alternatively, you might also enjoy a comedy performance from one of the famous comedians in residence such as Carrot Top and Terry Fator.

If all else fails, you can't beat a magic show from some of the most well-known magicians in the world such as Criss Angel and David Copperfield.
