Cobblestones Surf Forecast and Surf Report

Alright folks, Rusty here. Let's look at what's cookin' at just this one break for the next couple weeks. It's a one-horse town, so we gotta ride it or stay home.

The whole run is about one spot: Cobblestones. It's an exposed reef, for the advanced crew only, and it's about to get blasted by a constant stream of southwest groundswell. The whole sixteen days is full of power, but the wind is going to be the deciding factor. The water's at about 65°, which is a hair warmer than usual for this time of year, so that's a solid bonus.

We kick off on Saturday morning, September 5th. There's already a 12 ft swell from the SW with a 14-second period, but that 30 km/h cross-shore from the NNW is going to chop it all up. The combined energy is a hefty 5288, but the quality is poor. Honestly, looks more like a kite day than a paddle day.

Sunday the 6th keeps the energy high. The swell builds to nearly 15 ft by the afternoon with a very long 17-second period. The combined energy hits a massive 10988! But it's still messy with a fresh 30 km/h cross-shore wind from the south-southeast. That super long period at a reef can make things walled up, so it's for the brave and the strong.

Now, Monday the 7th of September morning is where we get our first real highlight. We've got a clean 12 ft swell from the SW at 16 seconds and a gentle cross-offshore breeze from the southeast at 15 km/h. This is it. The energy is still a massive 6877, but the clean wind will make for some lined-up, powerful waves for the experts. Get on it early because the wind goes lumpy in the afternoon.

Tuesday the 8th of September is the absolute standout of the whole forecast. The morning is clean, but the afternoon is a dream. 13 ft of SW at 16 seconds, a 15 km/h cross-offshore from the southeast, and the combined energy is 8277. It's glassy and powerful. That's the session to circle on the calendar.

Wednesday the 9th is still a champion. We drop to about 10 ft from the SW with 15-16 second periods, but now we get a clean offshore wind from the east-northeast. The morning is a moderate 25 km/h offshore, the afternoon is a gentler 15 km/h. The energy is still huge (5015 and 4050). If you miss Tuesday, this is your next best bet.

The swell backs off a touch into the second week. Thursday the 10th and Friday the 11th see the swell drop to around 7 ft or less, with periods getting weirdly long on Friday (20 seconds!). The winds are light and clean on Thursday afternoon, but the energy is down to 2112. Friday looks poor with that super long period and cross-shore winds.

We hit a rough patch from Saturday the 12th through Monday the 14th. Onshore winds and big, messy swell make for truly terrible conditions. Sunday the 13th has a nearly 15 ft lumpy mess. Just stay off the water.

There's another promising window on Tuesday the 15th of September. A clean, gentle cross-offshore breeze from the north-northeast and a solid 10 ft SW swell at 16 seconds. The energy is back up to 5110. This one is promising but less certain, keep it on the radar.

The rest of that week into the final weekend is average. Swell stays around 10 ft to 12 ft, but winds are mostly cross or light, so it’ll be a bit lumpy and not the quality of that first week.

Then a massive red flag for the 19th and 20th of September. The models are showing an 18 ft SW swell with combined energies over 16000. The reports say it's predicted to be too big for this break. If you are a true charger of the highest order, maybe you look, but for everyone else, it's a beach day.

Bottom line: Your golden ticket is Tuesday the 8th of September afternoon. Clean, powerful, and deep. Monday the 7th morning and Wednesday the 9th are your next best bets. Everything else is a gamble or a hard pass.

Stay sharp.
Rusty.
