SSW Holds Saturday, Fades Sunday
A Small Craft Advisory is posted for the ʻAlenuihāhā channel as well as Big Island south and leeward waters. Winds of 20 to 25 knots out of the east are forecasted with rough seas up to 10 feet. This advisory is posted through 6:00 p.m. Sunday. Inexperienced mariners should avoid navigating in these conditions.
**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: Waist/chest high waves are expected today. Guillermo swell fades and ENE trade swell mixes in.
Kona side: Wave heights waist/chest high are expected. Ankle/knee high for the spots not catching the SSW.
South: Wave heights waist/chest high are expected for spots catching the SSW swell. Spots catching trade swell wrap will be knee to chest high on the sets.
Ex-Guillermo swell continues to fade. Trade swell mixes in for easterly exposures. If tropical system, Hilda, continues on its forecasted path we expect swell to be generated for the islands around the middle of next week.
Our current south-southwest swell is expected to hold today and begin fading Sunday into early next week. Small overlapping swells expected late next week. Otherwise, pretty quiet.
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.
