Hawaii Surf Report/Forecast



 September 18-19, 2025


Forecast:  Surf along south facing shores will be small over the next few days, with mainly background south and southeast energy. A small to moderate, long-period, south-southwest swell will build Saturday into Sunday, and help boost south shore surf heights back up to near or above the September average. Surf along north facing shores should see a small increase Thursday as a short period northerly swell fills in. This small bump is expected to peak on Friday out of the north to north-northeast direction, followed by a short period north-northwest swell this weekend. Moderate to locally strong trades near and upstream of the area will lead to choppy conditions along east facing shores over the next several days. A slight increase of wind swell is expected over the weekend, due to a fetch of strong winds northeast of the state.
