tomorrow
🌅6-10a
A clean northeast breeze and the very low morning tide favor the still-playful south swell. Expect waist-to-stomach-high common surf, with lully head-high sets at better peaks. Scattered showers may pass through, but the mainly offshore wind should keep the faces orderly. Watch the shallow reef around the 8:30 AM low.

The south pulse holds near waist-to-stomach-high for most waves, with occasional head-high sets. Northerly winds remain clean for the South Shore, while the rising tide gradually softens smaller sections. Scattered showers and humid skies are possible as Fausto passes north of the islands.

2-8p🌙
A clean north to northeast breeze continues as the south swell eases only slightly, leaving waist-to-stomach-high surf and occasional shoulder-to-head-high sets. The afternoon high tide may mute the smaller waves. Numerous showers become more likely toward evening, with brief visibility and surface disruptions possible.

Wednesday
🌅6a-12p
The low tide helps waist-to-stomach-high surf and occasional head-high sets show on the reef, but weak southerly wind turns lightly onshore and adds chop. Numerous showers are expected in the humid, unsettled pattern. Conditions can vary quickly around passing showers; use extra caution over shallow reef near low tide.

12-8p🌙
The primary south swell builds a little, producing stomach-to-chest-high common surf and occasional head-high sets. Southeast wind is less favorable but remains light enough for textured rather than heavily disorganized conditions. Numerous showers remain the main limitation, while the afternoon high tide can soften smaller sections.

Thursday
🌅6a-12p
A solid south swell supplies chest-high common surf with occasional head-high sets, while a small long-period southwest pulse adds some extra set potential. Light east-northeast wind leaves mild texture. The morning low tide should sharpen the reef breaks, though scattered showers may still drift through.

12-8p🌙
Chest-high surf remains common, with lully head-high sets from overlapping south and southwest energy. Freshening east-northeast wind adds noticeable texture, especially later in the window, and a short-period southeast component further roughens the smaller waves. The late-afternoon high tide may make the surf less punchy.

Hurricane Fausto passing north of the islands weakens and shifts the local wind regime through Wednesday, bringing humid air and periods of numerous showers to Oahu. South Shore surf remains supported by a series of southerly swells near the usual late-July range, while the cyclone's dangerous east-shore surf stays largely separated from this coast.
Outlook: Drier, breezier east-northeast trades return from Thursday onward. The established south swell should remain rideable while a modest long-period southwest component lingers, but increasing trade-driven texture may become the limiting factor into Friday and the weekend.
