6-7p🌙 😁 Swell 5/10Wind 120° 9kt

Fun evening leftover NW swell with a bit of longer-period energy mixed in, plus some oblique NE swell that favors the eastern end a touch. Expect chest to head-high faces at most reefs with occasional overhead sets at the better peaks. Light-moderate ESE winds stay mostly offshore, keeping it fairly clean despite lingering clouds.

tomorrow

🌅6-10a 😁 Swell 5/10Wind 090° 4kt

Morning conditions set up nice: light winds and a low tide around 8:08a should help the swell show better shape and push. NW lines stay solid, with chest to head-high surf common and occasional overhead sets at the standout peaks. The NE energy is still around but remains secondary for most of the seven-mile stretch.

  • Sets:overhead, consistent
  • Surface:glassy

10a-2p 🙂 Swell 5/10Wind 070° 9kt

Still plenty surf through midday with steady NW swell: mostly chest to head-high, with occasional overhead sets when the better pulses show. Winds trend more ENE and a bit sideshore, so expect more texture and fewer clean faces than the early morning. Rising tide into early afternoon may soften some peaks, but the better sets should keep it moving.

  • Typical waves:shoulder
  • Sets:overhead, consistent

2-7p🌙 🙂 Swell 5/10Wind 080° 12G15kt

Afternoon into dusk stays in the chest to head-high zone with a few overhead standouts, though the swell is more steady than punchy. Trades are stronger and more sideshore, so the surface looks bumpy at many spots and the best waves will be more selective. Tide slowly drops after mid-afternoon, helping some reefs regain a bit of shape late.

  • Typical waves:shoulder
  • Sets:overhead, consistent
  • Surface:textured
  • Wind:080° 12G15kt
  • Tide:▲0.9ft 2:52p
  • Spectrum:

    • 012° 0.8ft 11s

Tuesday

🌅6a-12p 🙂 Swell 4/10Wind 080° 13kt

NW swell eases a notch but remains rideable: mostly stomach to shoulder-high with occasional head-high sets at the better peaks. Low tide mid-morning should help keep the waves more workable, but increasing trades add more lump and texture, especially later in the window. Best bet is to score the cleaner pockets early before the wind fully settles in.

  • Typical waves:chest
  • Sets:head, consistent
  • Surface:textured
  • Wind:080° 13kt
  • Tide:▼-0.1ft 8:30a
  • Spectrum:
    • 308° 3.6ft 12s
    • 010° 0.7ft 10s
    • 036° 0.7ft 9s
12-7p🌙 😕 Swell 3/10Wind 080° 14G18kt

More typical trade-wind North Shore: leftover NW swell provides stomach to shoulder-high surf with occasional head-high sets, but it gets harder to find clean faces as ENE trades run brisk and gusty. Mid-afternoon high tide can soften the smaller waves and make sections feel less punchy. If you go, look for corners that handle sideshore texture better.

  • Typical waves:stomach
  • Sets:head, lully
  • Surface:textured
  • Wind:080° 14G18kt
  • Tide:▲1.0ft 3:31p
  • Spectrum:
    • 309° 3.5ft 12s
    • 011° 0.6ft 10s
    • 038° 0.7ft 8s

A modest NW swell (around 310°) keeps the North Shore above seasonal average through Monday, with a smaller, more oblique NE pulse adding some extra motion but favoring the eastern end more than the main reefs. Weather stays mostly benign, trending less cloudy Monday, while winds transition from light/offshore this evening and early Monday to strengthening trades that add increasing texture Tuesday.

Outlook: After Tuesday, trades look to stay on the breezier side into midweek, which will limit surface quality during the day. The NW swell trend looks generally downward, keeping the North Shore in more of a small-to-fun range, with hints of a minor NW reinforcement as next weekend approaches.
