Barometric pressure

San Tan Valley is situated in a valley surrounded by mountains. The Superstition Mountains are to the north and the San Tan Mountains are to the south. The city's valley location affects the atmospheric pressure.

The surrounding mountains block or redirect winds, leading to a unique pressure pattern. As a result, the pressure in San Tan Valley can fluctuate significantly within a short period. This is especially true during weather front changes.

The valley's orientation also contributes to the pressure changes. During the summer, the sun heats the valley, causing the air to rise and pressure to drop. In the winter, the cooler air sinks, increasing the pressure.
