Cobblestones Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s cooking.

We’ve got one spot on the radar, and it’s a proper reef setup for the hardcore crew. The first real action kicks off on Saturday the 29th of August. Before that, Friday the 28th is a write-off – messy cross-shore wind and marginal conditions, not worth paddling out for. It’s a reef, so it handles swell well, but it needs the right wind.

The standout session of the whole run is Saturday afternoon, August 29th. We’re looking at 10ft of SW swell with a 17-second period – that’s proper groundswell, long interval, plenty of energy. The combined swell energy is strong (5452). And the wind? Dead offshore from the east at just 3 mph. That’s glassy, clean, perfect conditions for experts. This is the one to circle. The next morning, Sunday the 30th, is also excellent – 12ft SW swell, 17 seconds, and a light cross-offshore breeze from the NNE at 9 mph. Combined energy is very strong (6471). It’s going to be a solid, powerful weekend for the advanced crew.

Monday the 31st turns ugly – strong onshore winds and rain, with poor conditions. That mess lasts through most of the first week, with onshore winds and lumpy seas making it a no-go for surfing. The swell stays big (10ft to 15ft), but the wind is consistently wrong. From the 1st to the 4th of September, it’s blown out, windy, and rough. The 4th of September sees 16ft of SW swell but with 25 mph onshore winds – that’s just chaos, more for kite surfers than paddle surfing.

The next true highlight shows up on Monday morning, September 7th. It’s not as big – 8ft SW swell with a 13-second period – but the wind goes glassy from the northwest at just 3 mph. Combined energy is strong (4334). That’s going to be a clean, glassy morning for experienced surfers. The following Wednesday, September 9th, is another cracker – 12ft SW swell, 17-second period, with a light offshore from the northeast. The afternoon session is near-perfect: 12ft, 17 seconds, offshore breeze at 3 mph, and combined energy through the roof (7143). That’s the best wave quality of the whole outlook.

The second week holds promise but is less certain. The 10th of September has big 13ft WSW swell with a 17-second period and strong cross-offshore winds, but the energy is very high (up to 9736). It’s clean, but it’s only for the brave. After that, the wind swings onshore again from the 11th onward, and by the 12th, it’s blown out with 19 mph winds and lumpy conditions.

Crowds are possible at Cobblestones – it can get busy when it’s good. This spot is a reef, exposed to the SW, and it works best with a true south-southwest swell direction. That’s what we’re seeing. The water temperature is sitting around 65°F, which is a touch warmer than usual for this time of year.

If you’re an expert, you’ve got two absolute gems: Saturday afternoon, August 29th, and Wednesday afternoon, September 9th. The rest is a mix of big, windy chaos or marginal windows. Don’t waste your energy on the blown-out days.

Rusty.
