Hawaii Surf Report/Forecast



 September 17-18, 2025


Forecast:  Surf along north facing shores should see an increase by Thursday, as a short-period north swell arrives. This small surf is expected to peak on Friday out of the north to north-northeast direction. A fetch of strong trade winds developing far northeast of the state Wednesday into Thursday, should produce a moderate increase along east and select north facing shores Friday into the weekend. Otherwise, a small rise from the northwest is expected this weekend. Mainly background south and southeast swell energy is expected along south facing shores over the next few days. A small to moderate long-period south swell will boost south shore surf this weekend, with surf heights back up to around the September average (3 feet) this weekend.
