What time of day does the high temperature occur in Phoenix?

Answer 1

The early afternoon, between 1 PM and 3 PM, is usually the hottest part of the day. This is because the sunlight shining vertically carries more energy to the surface. By noon, when all sunlit objects have absorbed the maximum heat, they continue to heat the air and even shaded objects by re-radiation (infrared). So the solar energy received between 12 and 2 eventually has "nowhere to go" to be absorbed, and continues to raise the air temperature.

In the tropics and areas near water, these effects are mitigated somewhat, and clouds that form may also reduce surface heating. In desert areas, higher temperatures can persist well after sunset. Some areas in Arizona have reported temperatures over 100 degrees more than 2 hours after sunset.

Answer 2

Usually at some point in the afternoon, but they can occur at any time.

Answer 3

The high temperature in Phoenix typically occurs in the late afternoon or early evening, around 3-5 PM. This is because the sun has had the most time to heat up the surroundings by that time.

Answer 4

Never
