WHEN.SURF FORECAST Oahu South Shore

Waist to stomach surf is running on a mixed SSE pulse, with the better sets nudging shoulder high at the top reefs. The morning low tide is still helping early, though the rising push toward midafternoon starts to soften some peaks. Light sea-breeze texture and a stray shower keep it fair, not spotless.

Still around waist high at average spots with chesty sets, but the 3:51p high tide is likely to fatten plenty reefs through this window. Light texture hangs around under the sea breeze, so faces stay a little uneven despite usable south swell. Fun enough if expectations stay mellow.

Waist to stomach surf continues into the evening with occasional chest-high sets. Early in the window the post-high tide lull can make sections soft, then the gradual drop later should help shape a bit. Winds ease and trend more side-offshore, so surface quality looks a touch cleaner than midafternoon.

Clean dawn conditions line up nicely with the leftover south swell. Expect stomach-high surf at many spots with shoulder-high sets at the better peaks, especially around the 9:31a low tide. A brief early glass-off is possible before the trades settle in, while mostly cloudy skies may still squeeze out a passing shower.

The south swell still has enough push for waist to stomach surf and shoulder-high sets, but stronger trades add daytime texture as the tide rises. Shape should stay organized at exposures that like easterly wind, though not as polished as dawn. Mostly cloudy skies may bring a brief shower.

Surf trends a notch smaller and softer through the afternoon as the tide fills toward 4:33p. Expect mostly thigh to waist waves with occasional chest-high sets early, then less punch late. Trades stay generally favorable, so faces remain orderly enough, but the fuller tide will limit the better sections.

By Saturday morning the south swell looks smaller but still rideable, with thigh to waist surf and occasional stomach-high sets. The 10:00a low tide should help the weaker swell show a little better. Moderate trades keep some texture on it, though early windows may still look fairly clean.

Smaller surf continues through Saturday afternoon, mostly knee to thigh at average spots with some waist-high sets at the standout peaks. The big afternoon high tide will make many reefs soft and inconsistent. Moderate easterly trades keep a light bump on the face, so patience will be needed.
