6-9a 😁 Swell 4/10Wind 070° 15G20kt

Solid leftover south-southwest swell keeps most reefs in the stomach to chest zone, with better peaks nearing shoulder to head on sets. Trades are already side-offshore and gusty enough for texture, though early light still helps. The small morning high should keep shape fairly workable.

  • Typical waves:stomach
  • Sets:head, consistent
  • Surface:textured
  • Wind:070° 15G20kt
  • Tide:▲0.5ft 7:44a
  • Spectrum:
    • 181° 2.2ft 14s
    • 137° 2.6ft 8s
9a-12p 🙂 Swell 4/10Wind 060° 16G24kt

The swell trends down slowly but still offers waist to chest surf, with shoulder-high sets at the better-focused reefs. East-northeast trades strengthen through late morning, adding bump and some gust factor. The falling tide toward late morning may sharpen things without being especially shallow.

  • Typical waves:stomach
  • Sets:shoulder, consistent
  • Surface:textured
  • Wind:060° 16G24kt
  • Tide:▼0.3ft 11:51a
  • Spectrum:
    • 181° 2.1ft 14s
    • 135° 2.9ft 8s
12-4p 🙂 Swell 2/10Wind 070° 16G21kt

Afternoon surf settles a notch, mostly waist to stomach with chest-high sets still showing at magnets. Breezy trades keep the surface textured, and the short-period southeast energy adds some clutter. The tide is rising all afternoon, gradually softening the smaller corners as evening approaches.

  • Typical waves:waist
  • Sets:shoulder, lully
  • Surface:textured
  • Wind:070° 16G21kt
  • Tide:▲1.8ft 7:49p
  • Spectrum:
    • 181° 2.0ft 14s
    • 131° 2.6ft 6s
4-8p🌙 🙂 Swell 2/10Wind 070° 16G21kt

Evening holds onto waist to stomach surf, with occasional chest-high sets, while the long-period energy continues to ease. Trades remain side-offshore and a bit gusty, so expect texture rather than clean faces. The high tide near sunset may make the smaller waves a little softer, yeah.

  • Typical waves:waist
  • Sets:chest, lully
  • Surface:textured
  • Wind:070° 16G21kt
  • Tide:▲1.8ft 7:49p

tomorrow

🌅5-10a 🙂 Swell 1/10Wind 070° 12G16kt

The south swell is smaller but still fun-size, around thigh to waist for common waves with stomach-high sets at better peaks. Early trades should be lighter than midday, though leftover short-period chop keeps some texture around. The small high tide mid-morning is not a major limiter.

  • Typical waves:thigh
  • Sets:stomach, lully
  • Surface:textured
  • Wind:070° 12G16kt
  • Tide:▲0.6ft 9:16a
  • Spectrum:
    • 181° 1.6ft 13s
    • 131° 2.5ft 6s
    • 173° 0.4ft 26s
    • 155° 0.9ft 8s
10a-2p 😕 Swell 1/10Wind 070° 17G22kt

Midday trends smaller, mainly thigh to waist with a few stomach-high sets where the remaining south energy focuses. East trades are breezy and gusty, keeping texture on the surface and mixing in short-period clutter. The midday low is modest, so reef exposure concerns stay limited.

  • Typical waves:thigh
  • Sets:waist, lully
  • Surface:textured
  • Wind:070° 17G22kt
  • Tide:▼0.5ft 12:56p

    • 153° 1.3ft 8s
2-8p🌙 😕 Swell 1/10Wind 060° 14G18kt

Afternoon into dusk stays small but not flat, with thigh to waist surf and occasional stomach-high sets. Very long-period forerunners may appear, but they will be inconsistent. Trades ease a touch late, while the rising evening tide can soften the smaller sections.

  • Typical waves:thigh
  • Sets:waist, lully
  • Surface:textured
  • Wind:060° 14G18kt
  • Tide:▲1.7ft 8:32p

    • 172° 0.7ft 25s

Sunday

🌅5a-12p 😕 Swell 1/10Wind 070° 12G15kt

Sunday morning looks small and lully, mostly thigh-high with occasional waist to stomach sets as early long-period south energy starts filtering in late. Trades are moderate side-offshore, keeping some texture but not wrecking it. Isolated showers are possible, mainly passing quickly if they reach town.

  • Typical waves:thigh
  • Sets:waist, sparse
  • Surface:textured
  • Wind:070° 12G15kt
  • Tide:▲0.8ft 10:38a
  • Spectrum:
    • 189° 1.2ft 12s
    • 171° 0.6ft 22s
    • 144° 1.2ft 7s
    • 181° 0.5ft 16s
12-8p🌙 🙂 Swell 1/10Wind 060° 14G18kt

Long-period south swell should become more noticeable through the afternoon, lifting common waves into the thigh to waist range with stomach to chest sets at standout reefs. Expect waits between the better pulses. Trades remain moderate and textured, while the mid-afternoon low stays fairly mellow.

  • Typical waves:thigh
  • Sets:chest, lully
  • Surface:textured
  • Wind:060° 14G18kt
  • Tide:▼0.7ft 2:38p
  • Spectrum:
    • 171° 0.9ft 20s
    • 187° 1.2ft 12s
    • 146° 1.4ft 7s

Breezy easterly trades are the main local weather feature, with side-offshore wind on the South Shore and just enough short-period southeast clutter to keep surfaces textured. The older south-southwest swell is steadily easing through Saturday. A new small, long-period south swell begins to show late in the weekend, but the first pulses look inconsistent.

Outlook: Monday should see the new south swell near its peak, likely keeping the South Shore rideable with better long-period shape if winds do not get too gusty. Trades remain common early next week, then may ease slightly later in the week, with mostly typical early-summer shower coverage.
