The Lowdown
Alright, let’s talk in feet then. Over the next 16 days at Fortunes Rocks Beach, there’s not much to get excited about. Waves are mostly tiny, rarely cracking waist-high, and the wind’s usually onshore or cross-onshore, messing up the surface. Water’s about 67°, a touch warmer than normal, which is nice.
First real swell shows Monday morning, August 17 – a weak 4ft swell from the south, but it’s cross-onshore at 12 mph, so it’s choppy and weak. Combined energy is only 68 – barely a pulse. The next few days are similar: knee-high waves in the 2-3ft range, mostly from southeast, with poor wind.
Tuesday afternoon, August 18 offers a cleaner window: 3ft from SSE, cross-offshore breeze from NE at 6 mph, and 116 energy (moderate). Still small, but at least it’s not a washing machine.
Then it’s a dry, poor run through to Sunday, August 23 afternoon – a 4ft SSE swell hits but it’s on a 12 mph onshore wind, so no.
The only real standout is Wednesday, August 26, morning. Glassy calm with a light 3 mph WNW breeze, a clean 1ft southeast groundswell running a super long 15-second period. Energy is low at 69, but with that glassy surface, those long-period lines will give you the cleanest little rides of the whole outlook. Crowds can pop here, but on a morning this small, you might have it quiet.
Thursday, August 27, morning is another glassy session – 1ft SE swell at 12 seconds, energy 122 (moderate) – clean and tiny, only for a log.
The rest of the run into the end of August and the 31st is back to poor, small, onshore junk.
Best bet: Wednesday, August 26, morning at Fortunes Rocks Beach – 1ft SE groundswell, glassy, clean. It’s the kind of morning you bring your longboard and just enjoy the quiet.
