Big Island Surf Forecast, Friday November 21, 2014
Hilo side:Surf is expected in the head high to possibly even slightly overhead at the best breaks due to the tradeswell. Waist to shoulder high surf due to the northwest wrapping around the island.
Kona side: Spots that catch some of the new north-northwest wrap could see a slight bump in wave heights possibly up to waist high. Breaks not exposed to the swells will be flat today.
South:Southeast shores open to the trade swell could see waves up to head high or more, though sloppy and choppy conditions are expected. Waves expected thigh high at best for spots catching the small southwest.

Trade winds are breezy with a slow weakening trend expected. Today through Saturday short-period tradeswell is expected to continue affecting windward shores. Conditions will be choppy and sloppy.
Our current west-northwest swell (300-330°) is expected to hold through Saturday. Expected wave heights are up to possibly head high for the Hilo side and waist high for the Kona side but inconsistent.
Another northwest swell (305-330°) is expected to build late Sunday. We could see wave heights head high or more for the Hamakua coast in the afternoon. Kona side will be shadowed but still catch a fraction of the wrap. There’s also the possibility of a north swell for the middle of next week.
Our current small bump (220-190°) is expected to be waist high or less at the best breaks through today and fades through the weekend. Otherwise, super small trace amounts of swell expected out of the SPAC. There isn’t much on the horizon to get excited about.

Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
