Swell Summary
An ongoing small, short period north northeast (10-40 degree) swell will maintain near waist high surf along many north to northeast-facing shores through tonight. A small, medium period northwest (320 degree) swell is scheduled to arrive late Friday and fill in Saturday morning. This swell will maintain waist to near head high surf along many north-facing shores, near knee to waist high surf along west-facing shores Saturday. East-facing shores will experience continued choppy conditions through Friday in response to several days of this upstream fresh trade fetch. Surf along east-facing shores will slowly subside going into this weekend as trades fall off a notch. Small, background south swell energy will maintain knee to chest high surf along many southern shores. A very small, medium period south southwest bump in swell arriving tonight into early Friday will result in a small boost in weekend surf.
