Barometric pressure

Issaquah is surrounded by the Cascade Mountains to the east and Puget Sound to the west. These geographical features impact the atmospheric pressure. The mountains block some air masses from reaching the city. The Puget Sound brings moisture-laden air from the ocean. The combination of these two factors affects the pressure.

The city's location in a valley also plays a role. The valley traps air and slows its movement. This contributes to the relatively stable pressure in Issaquah.
