**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 north-northwest are expected to get up to head high maybe overhead at the best breaks on the sets.
Kona side: Wave heights are expected to be waist high or less today with belly high waves on the sets at the best spots at the best tides.
South: Kona side expected to get mainly wave heights under waist high.
Our current north-northwest swell is expected to continue today, then fade through the afternoon. A solid large northwest swell is expected to build Wednesday, peaking overnight and fading through the second half of the week. The Kona side will be largely shadowed by the other islands but some energy will still get through bringing wave heights up to chest/head high or even a few feet overhead at the best exposed breaks.
A small southwest swell continues to build Tuesday before fading back down Wednesday.
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.
