In spite of our warmer than average temperatures this week, October's temperatures tend get cooler at a fairly even pace. By the end of the month, average high temperatures fall to the mid 70s!

The September Review is in! Temperatures were slightly above-normal for September here in Las Vegas, and despite getting some rain at the end of the month, precipitation was slightly below-normal.

Depending on your location, this monsoon was relatively dry up until the last few days, where Las Vegas observed 0.30 inches of rainfall, bringing the total rainfall for the monsoon up to 0.50 inches. For context, average is 1.03 inches from June 15th through September 30th.
