Cobblestones Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s coming down the pipe at Cobblestones.

We’ve got a solid run of swell on the way, but the first few days are going to test your patience. A lot of strong wind and rain in the picture before things clean up proper.

Right out of the gate, Monday the 17th is a write-off. A big WSW swell of 13.1ft to 18.0ft is getting thrashed by 28 mph onshore winds. The combined energy is massive—9988 to 9232—but it’s just a mess. Don’t even think about it.

Tuesday the 18th is still not great. The swell drops a little to 14.8ft, but the wind is still cross-onshore and it’s choppy. The energy is still very high, around 10858 in the morning. This is big, powerful, and ugly.

Wednesday the 19th starts to show some promise. Swell stays at 14.8ft from the WSW with a long 15 to 16-second period, and the wind finally turns onshore but light. The energy is still high—8656 to 10159. The conditions are described as marginal, but at least it’s not blown out. This is for experienced surfers only, as 14.8ft is well into big-wave territory.

Thursday the 20th is where we start to see a real window. The swell is still a solid 13.1ft to 11.5ft from the WSW/SW, period hanging around 15 to 16 seconds. The energy is still strong at 7197. But the wind turns light, with a light cross-onshore breeze in the morning. That’s the first day that’s actually surfable for the crew that can handle the size.

Now, the standout window is from Friday the 21st through the weekend. The swell starts to ease into the 9.8ft to 11.5ft range, but the period stays long. The real magic happens on Saturday the 22nd morning: we get a 9.8ft south-west groundswell (16-second period) with glassy conditions. The wind is dead calm—just a slight air. The energy is still strong at 4414, but it’s clean. That morning is the best of the first week for anyone experienced. The afternoon drops to 8.2ft and still clean-ish.

Sunday the 23rd gets ugly again with 22 to 28 mph winds and a 13.1ft to 16.4ft swell. The energy spikes to 7285 in the afternoon, but it’s a total mess. Skip it.

Monday the 24th stays windy and lumpy with 19 mph cross-shore winds and 13.1ft to 14.8ft swell. Not great.

But then, we get a second, possibly better window. Tuesday the 25th morning brings a 9.8ft SSW swell with a clean offshore wind from the ENE at just 3 mph. That’s a gorgeous combo for a spot that prefers SSW swell. The energy is moderate at 2800, and the conditions are described as excellent for experienced surfers. That’s a serious contender for the pick of the entire forecast. The afternoon gets even smaller at 6.6ft, with a very long 18-second period and glassy conditions. For the right tide, that afternoon glass-off could be magic.

Wednesday the 26th morning keeps the good vibes with another glassy morning—8.2ft, 16-second swell, and ENE wind at 3 mph. The energy is 4248. That’s another excellent session for the crew who can handle the set waves.

From there, the swell slowly fades into the end of the month. The mornings of Thursday the 27th and Friday the 28th offer clean, smaller surf (6.6ft to 6.9ft) with offshore or cross-off winds. The energy drops to between 1714 and 2990. It’s not pumping, but it’s clean and fun for a log or a fish.

Then we get a pulse towards the end of the first week of September. Saturday the 29th sees a jump to 14.8ft from the WSW with a moderate cross-off wind and clean conditions. The energy is back up to 7762. That one is worth circling for the big-wave hunters.

After that, the forecast slips back into strong onshore winds and blown-out conditions from Sunday the 30th through Monday the 31st, with swells of 11.5ft to 16.4ft and winds up to 31 mph. Messy.

And finally, Tuesday the 1st of September, a huge 18.0ft south-west swell with 16-second period rolls in. The energy is astronomical at 15631. The wind is onshore but moderate at 12 mph. The notes say it’s simply too big for this break. That one is a straight pass.

So for my money, the absolute best on offer is Tuesday the 25th of August, morning session at Cobblestones. Clean, offshore wind, solid 9.8ft SSW groundswell, and moderate energy. After that, Saturday the 22nd morning with glassy conditions and a 9.8ft swell is a close second for clean, big-wave fun.

Ride safe, catch a good one.
