A common saying in Arizona which is frequently used is, “but it’s a dry heat!” Well that doesn’t always apply during the monsoon season. Prior to 2007, the start of the monsoon was defined as when the dew point for 3 consecutive days is 55 degrees or higher. This means that the air holds more moisture than usual. Air conditioners are designed to remove this humidity from the air. This water or condensation flows through PVC tubes to the outside of the house. You’ve probably noticed them on the side of your house. Now what happens if they don’t work?
Arizona Summer Thunderstorm Season is know as Monsoon
The beginning of July, the monsoon made its entrance. The monsoon brings with it high winds, dust and down pours which can result in flash flooding.

During July-August-September the average rainfall is 2.65 inches. Click to learn more. Continue reading “The Monsoon Season in Phoenix”
