WHEN.SURF FORECAST Oahu South Shore

Small but fun south swell peaks through the morning, with common stomach to chest-high surf and occasional shoulder to near head-high sets at the better reefs. An early extra-low tide keeps it punchier and a bit shallow in spots. Fresh trades stay fairly groomed but leave a textured face, with a few passing clouds possible.

South swell still runs near peak, though the late-morning high tide softens some spots. Expect mostly stomach to chest-high waves with shoulder-high sets, plus steady trade texture through the lineup. Skies trend sunnier after any early clouds, and the stronger midday wind keeps it from getting truly clean.

Plenty of long-period south energy remains into the afternoon, with chest-high surf and occasional shoulder to head-high sets at the better peaks. The dropping tide adds a little more shape later in the window. Trades stay brisk and gusty from the northeast, so surfaces remain textured rather than clean.

The south swell eases a notch Sunday morning, but there should still be playful waist to stomach-high surf with occasional chest-high sets. A very low dawn tide can make the early hour a bit shallow and uneven. Trades hold from the ENE, keeping some texture on the water rather than true morning glass.

Fading south swell and a midday high tide pull the surf down a bit through Sunday afternoon. Look for mostly waist to stomach-high waves with stray chest-high sets, while firmer ENE trades add more sideshore lump than on Saturday. Mostly sunny weather should keep the session bright, just a little ruffled.

Leftover south swell keeps the South Shore rideable Monday morning, though smaller than the weekend, around waist-high with occasional chest-high sets at the better reefs. Early low tide helps some spots wake up, but brisk ENE trades run fairly cross-textured and can stretch the wait between worthwhile sets.

By Monday afternoon the swell is on the small side and the higher tide takes more punch out of it. Expect knee to waist-high surf for many spots, with occasional stomach-high sets where the reefs focus the remaining south energy. Trades stay up, so conditions lean ruffled and only marginally inviting.
