Cobblestones Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a solid 16-day window to look at for Cobblestones, and I’m telling you, there’s some serious energy on the table. This is an advanced reef break, and it’s exposed to the swell, so when it’s on, it’s on. The water is sitting at 66°, which is a touch warmer than normal for this time of year – not a huge deal, but nice if you’re not wearing a thick suit.

The first few days are a write-off for any kind of decent surf. We’ve got solid swell coming in, but the wind is just trash. Wednesday the 2nd through Saturday the 5th, the wind is either onshore or cross-onshore and strong. Swell is big – 12ft to 16ft – but it’s all messy and blown out. The combined energy is massive (4447 to 11425), but with that wind, you’d be a fool to paddle out. The setup looks more interesting for kite surfing than paddle surfing.

Sunday the 6th and Monday the 7th are still marginal. The swell stays big (13ft to 16ft) and the wind is cross-shore, so it’s lumpy and not great. The energy is still high (6346 to 12417), but the quality isn’t there for a good session.

Now, here’s the standout. Tuesday morning, the 8th of September. This is the one. We’ve got a 13ft SW swell with a very long period of 17 seconds. The combined energy is 8345 – that’s strong. But the real story is the wind: glassy. Dead calm. For an exposed reef like Cobblestones, that’s about as good as it gets. The conditions are exceptional for expert surfers, and the sets will be long, powerful, and clean. This is the day to clear your schedule. Crowds are a possibility here sometimes, so get in early. The long period means it’ll be a groundswell, so expect long waits between sets, but the shape on the reef will be world-class.

The rest of the second week is a mixed bag. Wednesday the 9th stays clean with offshore winds and 8ft to 10ft swell, but the energy drops off (2803 to 3227). It’s good for experienced surfers, but not the standout. Thursday the 10th through Monday the 14th is mostly a write-off again, with onshore winds and choppy conditions. The swell is still there, but the wind just kills it.

Tuesday the 15th morning, we get another glassy window with a 10ft SW swell and 13-second period. The energy is moderate (3280), and conditions are excellent for experienced surfers. It’s not as big or powerful as the 8th, but it’ll be clean and fun.

Finally, Wednesday the 16th brings an 12ft SW swell with a very long 18-second period, and energy at 7312. The wind is light cross-onshore, so it’s not perfect, but it’s still worth a look for those who can handle a bit of texture.

To sum it up: the 8th of September is the clear winner. Glassy conditions, big swell, and a long period. Don’t miss it. The 9th and 15th are good backup days. The rest is either blown out or marginal. Keep an eye on the forecasts, because things can change.

Rusty.
