**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 expected waist/chest high. Some spots with northwest exposure get up to overhead and possibly even double overhead.
Kona side: Wave heights are expected to be head high or more today as wrap from the northwest fills in. South-southwest is knee high or less.
South: Breaks open to the south-southwest swell are around knee high today.
Trade swell is expected to remain pretty small.
Our current south-southwest continues to ease through Monday.
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.
