Big Island Surf Forecast

Hilo side: Waist/chest high waves expected today for well exposed trade swell breaks. Best breaks could see sets up to shoulder high waves from time to time.

Kona side: Wave heights waist high are expected in the morning with an easing trend through the day. The best breaks could get chest/shoulder high sets early on.

South: Wave heights waist high are expected in the morning with an easing trend through the day. The best breaks could get chest/shoulder high sets early on.

Our current south-southwest swell is expected to continue to slowly fade through the week. Small rideable pulses out of the south are expected but nothing super notable. August 3-5th we expect a new knee/thigh high swell with a better angled swell expected the 5-8th with waves possibly up to waist high or more.

Trade swell will push into northeasterly exposures. Otherwise, the north Pacific is looking very 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.
