Swell Summary
South facing shores will remain small through Friday, then reach near summer average heights this weekend as a new long-period southwest swell arrives from the Tasman Sea, along with a new small short-period south-southeast swell. Surf along east facing shores will continue to remain rough and choppy due to the fresh to locally strong trade winds and a small short-period northeast swell that is expected to fill in this weekend. Surf along north facing shores will remain nearly flat through the weekend.
