**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 for spots exposed to the swell are expected to be shoulder/head high today. Spots without direct exposure to the swell will be smaller.
Kona side: Wave heights are expected to be waist/chest high today. The best breaks could get up to shoulder high from time to time.
South: Wave heights are expected to be waist/chest high today out of the northwest. South-southwest will build up to shoulder high by sunset.
A new south-southwest is expected to build in Thursday and peak Friday up to shoulder/head high at the best breaks. Another smaller south-southwest is expected for the weekend but not expected to increase wave heights over what the fading swell will already be providing.
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.
