Humidity in June

When reviewing the weather forecast for San Diego in June, you must also take into consideration the humidity. The temperature is important, but the humidity will affect how you spend your days outdoors.

The relative humidity in June ranges between 65 and 81 percent, with an average of  73 percent. Generally, the humidity begins to fall during the middle of the day, before once again picking up during the late evening hours.
