Surfing in the Seattle Area & Seattle Surf Locations Map
Seattle has some great surfing but you need to drive a few hours outside the city to get to it. No worries though it's typically a pretty drive once you get outside the city and the surf usually is worth the work.
The surf is typically big and powerful all year-round, but especially so in the winter. The air and water temperatures in the winter are freezing, I mean really cold so come prepared. In the summer and spring/fall the weather can be nice and warm, but the water is always cold so best to bring a thick wetsuit at all times of the year.
