Big Island Surf Forecast

Hilo side: Wave heights are expected shoulder high to overhead today.

Kona side: Wave heights knee/thigh high are expected today. Breaks open to the southeast could see waves due to Niala swell – largest in the morning.

South: Wave heights chest/head high are expected for the breaks open to the swell generated by Niala.

Small SSW swell is expected to continue today. Small scale south-southwest swells are expected through the end of the month but nothing super notable.

Trade winds will continue to generate short-period choppy surf at moderate levels along east facing shores. Dropping a notch Monday and easing further on Tuesday.

We are looking at fading east-southeast swell from Niala. The smaller islands could see southerly tropical swell from Niala Monday and Tuesday.

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.
