Arizona temperature year round

Although the weather is always sunny around the year alongside the air being dry, one thing that doesn’t stay constant across the duration is the temperature level. Winter periods comes with a mild feeling, while spring and fall give a warm touch. Summer, on the other hand, comes with a substantial amount of temperature rise, which is above 38 degrees always.

These results are based on a test carried out and data that have been gathered over time. The coldest time of the year always occurs in December, when there are days with temperatures low as 19 degrees as maximum and 7 degrees Celsius for the minimum.

The hottest times fall in early July, with the average temperature peaking as high as 41 degrees and a lowest of 28 degrees.

In Arizona, how does relative humidity change with temperature?

Relative humidity could be affected by changes in temperature since it tells you how close the air is to being saturated. i.e., when the relative humidity reaches 100%, then the air is saturated.

Therefore there is a direct relationship between the level of water vapor in the atmosphere and the relative humidity

Relative humidity also varies with changes in the air temperature. If the water content in the atmosphere remains constant, when there is an increase in the temperature, the relative humidity decreases, and in a case of a decrease in the temperature with the water content in the atmosphere remains constant, then the relative humidity increases.

This is so as a result of the fact that colder air doesn’t require as much moisture as warmer air to become saturated.
