Big Island Surf Forecast

Hilo side: Waist/head high surf is expected today. The best focal points for the trade swell could see waves up to overhead on the sets. Messy conditions continue due to the winds.

Kona side: Wave heights of knee/waist high are expected for southerly exposures. Best breaks could get slightly bigger on the sets.

South: Wave heights knee/thigh high today. Spots catching the trade swell could get a little bigger on the sets.

Our current mix of south and south-southwest swells brings waves of waist high or less through the end of the week. Storms firing up in the Tasman Sea could bring us swell in about a week.

Flat conditions expected out of the northwest. A west-northwest is expected to build Friday and bring waves for the weekend. A northwest pulse could fill in midweek.

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.
