New Swell Expected to Fill in Tuesday
Alerts (as of 1:00 a.m.)
A Small Craft Advisory is posted for the ʻAlenuihāhā channel as well as waters to the south and west of the Big Island through 6 a.m. Sunday.
**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 trade swell are expected to be waist/shoulder high today.
Kona side: Wave heights are expected to be knee/thigh high today, some spots could get up to waist high.
South: Wave heights are expected to be ankle/knee high high today, some spots could be flat. Spots catching trade swell could get up to waist/shoulder high.
Only trace amounts of swell for the weekend out of the south. Chances are looking good that a swell will line up starting Tuesday, peaking Wednesday and Thursday.
Tropical system Conson (east of Mariana Islands) isn’t looking like a wave maker for us. Models are showing activity in the West Pacific so there is potential for swell energy out of that region in the future.
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.
