Barometric pressure

Tacoma is surrounded by the Olympic Mountains to the west and Puget Sound to the east. This unique landscape affects the atmospheric pressure. The Olympic Mountains block moisture from the Pacific Ocean. As a result, Tacoma's weather is drier than expected for a coastal city.

Puget Sound's water absorbs and releases heat slowly. This causes temperatures to remain relatively stable. The sound's influence also leads to increased cloud cover. This, in turn, affects the barometric pressure. Tacoma's weather is often overcast, especially during the winter months.
