**Click directly on the images below to make them larger. Charts include: Big Island projected winds, tides, swell direction & period and expected wave heights.**
Hilo side: Wave heights are forecast from shoulder high or more at the best exposures today.
Kona side: Wave heights are expected to be knee/waist high from wrap out of the northwest but dropping. Otherwise, it should be pretty flat.
South: Wave heights are expected to be knee/waist high or more from wrap out of the northwest depending on the exposure but dropping through the day. Otherwise, it should be pretty flat out of the south.
Old northwest swell is fading through the weekend while a new small north-northwest shows for the Hilo side with some sneaky sets up to knee/waist high for the Kona side. Sunday another northerly swell fills in but it will also be shadowed by the other islands.
A modest trade swell will continue for north and east exposures.
The moderate south swell associated with a recent batch of gales over the Tasman Sea is expected to fade through the weekend. Nothing significant is expected out of the SPAC.
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.
