Why Only 2 Wind Directions In Seattle?
SEATTLE - Astute weather observers have probably noticed that the wind mainly either blows from the south or the north in the Seattle area.

That's due to being sandwiched in between the Olympics to our west and the Cascades to our east. Those mountain ranges act like a wall, restricting our exposure to a west or east wind -- although sometimes Seattle get a strong east wind coming out of Snoqualmie Pass.

We usually get south winds during cloudy or rainy weather, while north winds usually come with the sunny, dry weather.
