🌅6-8a 😕 Swell 1/5Wind 070° 19G24kt

Strong ENE trades are blowing the South Shore out with steady chop and passing showers. A small 14s S pulse offers occasional chest-high sets at the best reefs, but most spots see thigh-to-waist runners. Rising tide toward the late-morning high won’t help the already bumpy shape. Expect lots of wind texture and quick drift.

8-10a 😕 Swell 1/5Wind 070° 20G26kt

Trades remain strong ENE, keeping conditions blown out. Long-period S energy mixes with short-period SE wind chop, so sets still pop chest-ish at standout reefs, but most waves are thigh-to-waist and sloppy. The incoming tide peaking late morning further softens the small swell. Expect drift, warble, and intermittent showers riding through.

10a-2p 😴 Swell 1/5Wind 070° 21G27kt

Peak high tide around midday plus strong ENE trades make for the day’s weakest window. Small 13s S lines struggle against the chop and tide, with most breakers knee-to-thigh and occasional waist sets where reefs focus best. Expect steady drift and poor shape; showers still possible but less frequent toward early afternoon.

2-6p🌙 😕 Swell 1/5Wind 070° 20G26kt

Trades stay brisk ENE and keep it blown out, but the outgoing tide toward an evening low gives the small S swell a tiny bit more push. Expect thigh-to-waist surf with occasional plus peaks to chest at the best reefs. Still bumpy with strong cross/onshore drift; only brief, clearer skies between passing clouds.

🌅6-10a 😴 Swell 1/5Wind 070° 19G24kt

Trade-wind SE chop builds while the long-period S swell eases further. Early low tide offers a bit more break, but strong ENE winds keep it blown out. Most spots run knee-to-thigh with lully waist-high sets at best exposures. Expect lots of crumble and drift under partly cloudy skies with a few stray showers.

10a-2p 😕 Swell 1/5Wind 070° 19G24kt

Short-period SE windswell is the main player now, adding size but not quality, while the S groundswell fades. Expect thigh-to-waist surf with occasional waist-plus pulses at the better reefs, but steady ENE trades keep it crumbly and drifty. The midday high tide softens whatever push is there. Skies partly sunny with isolated showers.

  • Typical waves:thigh
  • Sets:waist, sparse
  • Surface:blown out
  • Wind:070° 19G24kt

2-6p🌙 😕 Swell 1/5Wind 070° 19G24kt

Brisk ENE trades continue with dominant SE windswell. The draining tide into the evening low adds a touch of energy, but the surface stays messy and sideshore-onshore. Look for thigh-to-waist surf and the rare waist-plus set at select reefs. Plenty of chop and current; a few clearer spells between clouds by late day.

  • Typical waves:thigh
  • Sets:waist, sparse
  • Surface:blown out
  • Wind:070° 19G24kt

    • 182° 1.1ft 12s

A strong high far to the north is driving fresh to locally near-gale trades, piling up short-period SE wind chop around the South Shore while a small, fading long-period S pulse lingers. Expect choppy seas, brisk drift, and passing windward-favored showers; east shore surf is elevated but does not translate cleanly to south breaks.

Looking ahead: Trades gradually ease a notch Friday night into the weekend with fewer showers. South Shore surf trends small as the long-period S background fades, while short-period SE windswell remains the primary, messy source before slowly backing down. Unless winds back off more than expected, quality stays modest with mainly rideable, choppy surf through Saturday.
