Cobblestones Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s coming for Cobblestones.

Right out of the gate, this is a reef setup that knows how to pack a punch, and we’ve got a real mixed bag of conditions over the next couple of weeks. The water is sitting at 64°, which is a degree warmer than average for this time of year, so you can probably get away with a step down in rubber.

The first proper window to look at kicks off on the morning of Thursday the 10th. We’ve got a solid 7ft SW swell at 14 seconds pushing in, and it’s clean with a moderate breeze. The combined energy is sitting at 2327 (moderate), so there’s some real weight behind it. Friday the 11th keeps that momentum going with a similar 7ft SSW groundswell in the morning and building to a hefty 10ft WSW by the afternoon, with periods stretching to 18 seconds – that’s very long period, meaning it’ll turn into proper lines on the reef, but at a beachy it might just stand up too fast. Winds are cross-off both days, so you’ll get some decent shape, but that early Friday wind is up at 30 km/h (19 mph), so it’s gonna be a bit of a wrestle getting out.

Now, during the Saturday the 12th through Sunday the 13th, the wind shifts onshore and it gets rough. Swells stay big – hitting 12ft – but it’s a complete mess. That is not paddle-surfing territory. Honestly, with those strong onshores and the power in the water, you’d have more fun rigging a kite.

Monday the 14th is a standout if you’ve got the skills. The swell is still a solid 12ft from the SW, period at 14 seconds, and the combined energy is cooking at 5302 (strong). But the key is that light easterly cross-off breeze and morning clarity – that window from dawn on Monday is going to be clean, raw, and heavy. This is expert-level territory. Do not take a foamy out there.

From Tuesday the 15th through most of the following week, the conditions are marginal at best. Winds are cross or cross-on, the swell hangs around the 8ft to 10ft range, and while it’s clean-ish at times, the commentary says it’s all fairly choppy or cross-chop heavy. Nothing to get excited about until the 20th of September.

Sunday the 20th is the real killer window. The morning has a 15ft SW groundswell, period of 15 seconds, and a glassy easterly cross-off wind. The energy reading is 7879 (very strong). That is going to be a heavy, clean day of well-formed reef waves for experts. Monday the 21st is nearly as good – same 13ft SW swell, same long period, and light offshore N winds at 10 km/h (6 mph). Another morning of exceptional, clean surf. These two days are the best on offer in this whole 16-day outlook.

After that, it tapers off. Winds pick up again around the 24th and 25th, with the swell dropping a bit but the energy still strong (over 4000), but it’s all onshore and lumpy – a no-go.

So mark your calendar: the real magic is Sunday 20th and Monday 21st of September at Cobblestones. Dawn patrol, expert sticks only, and enjoy the 14ft groundswell.

Rusty.
