WHEN.SURF FORECAST Oahu South Shore

Thigh-high common waves with waist-high sets at better reefs, helped by the early negative low. Light to moderate trades stay mostly favorable, though leftover short-period SE texture may keep it from feeling totally groomed. A few passing showers are possible early, then brighter weather as the morning goes on.

Mostly thigh-high surf with occasional waist to low-stomach sets. The rising tide toward a 2.1 ft high will soften the smaller waves and add some water over the reef. Trades stay manageable but not glassy, with a little short-period bump mixed into the cleaner south lines.

The small south-southwest pulses look a little more useful later in the day, with waist-high common waves and stomach-high sets where the better lines focus. The tide drains through the afternoon, improving shape after the early high-water softness. Light trades keep the surface lightly textured, locally fairly clean.

Waist to stomach-high surf should be more organized, with shoulder-high sets at the better peaks. The dawn low is quite shallow, so use care over the reef before the tide fills in. Light NE trades are favorable, and the long-period south energy should make for more defined sets.

Stomach to chest-high surf is likely, with head-high sets starting to show as longer-period energy fills in. The 2.4 ft high tide early afternoon may make some spots full, then the evening drop should add more shape. Light NE trades keep conditions clean to lightly textured.

Chest to shoulder-high surf should be common, with overhead sets at the standout reefs as very long-period energy builds. The -0.4 ft low near dawn creates notably shallow reef conditions, especially with the added power. Light NE trades are favorable, but the biggest lines may arrive with long waits.

Head-high surf becomes common with well-overhead sets possible at the best exposed reefs as the long-period swell continues rising. The 2.6 ft peak tide may add runup and make some spots full, though power remains. Light to moderate NE trades keep the surface mostly clean, with plenty kine energy.
