WHEN.SURF FORECAST Oahu South Shore

Waist-high surf continues with occasional lully chest-high sets from overlapping south pulses. The falling tide trends toward a low near the end of the window, helping wave shape on the reef. Easterly trades stay moderate and cross-textured, though a few cleaner dawn intervals are possible. A passing shower cannot be ruled out.

Waist-high surf holds through midday, with chest-high sets still showing but separated by lulls. The lowest tide is at the start, then water levels steadily fill in and can soften some reef sections. Moderate easterly trades add texture rather than a full chop. Early scattered showers should become more isolated.

Waist-high surf persists into the afternoon, with occasional chest-high pulses from the lingering longer-period south energy. A high tide around mid-afternoon may make the smaller waves less defined at some reef zones. Easterly trades remain moderately textured, with isolated showers possible, but no major weather concern is expected.

The fading south swell leaves thigh-high surf at average spots, with intermittent waist-high sets where the longer-period energy refracts in. The late-morning low tide should keep the small surf relatively playful, but use normal reef awareness. Moderate east-northeast trades maintain texture, and an isolated shower is possible.

Small thigh-high surf dominates, with occasional waist-high sets from the fading south swell. A broad afternoon high tide further reduces the push on smaller reef sections. East-northeast winds are favorable in direction but still add a light texture, while brief isolated showers become possible toward evening.

Small, longer-period south energy keeps thigh-high surf in the water, with lully waist-high sets at favored peaks. Water levels fall toward a late-morning low, which helps the modest swell break more cleanly over shallow reef. Easterly trades remain moderate and textured. Scattered brief showers are possible during the morning.

The south swell eases to mainly knee-to-thigh-high surf, with only occasional waist-high sets from the remaining 15-second energy. The afternoon high tide makes the small surf less reliable across many reef zones. Moderate east-northeast trades keep a textured surface, and isolated showers may pass through later in the day.
