While not as brutal as July, the weather in Las Vegas is scorching in August, with the average daily high temperature of 102 degrees, and average daily low of 79.3. The average daily temperature is 90.6 degrees Fahrenheit, or 32.55 degrees Celsius.
If the 90.6 average doesn’t sound too bad, remember that is the average temperature for each of the 24 hours in the day. Sometimes, (5 a.m. for example), it will be cooler, and other times, (3 p.m.) it will be incredibly warmer.
Overall, August is the second hottest month in the Las Vegas valley. Yet that doesn’t stop millions from visiting. In fact, according to the Las Vegas Visitors and Convention Bureau, Las Vegas hotels still have a 90.4% occupancy rate in the month of August.
This is due in part, to several large conventions that have chosen August for their convention dates. Two of the largest conventions in Las Vegas take place in August.
The large Las Vegas Market, for example is a bi-annual trade show for shoe and clothing retailers. It brings 50,000 visitors to the city in the early part of the month. Similarly, the ASD Las Vegas Convention for resellers of consumer goods brings in 44,000 tourists. It too is often held in the first part of August.
