Cobblestones Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a wild 16-day window ahead, with some serious size coming through, but the wind is going to be the real story. The early part of the week is a write-off with onshore junk, but if you’re an expert and you can wait, there’s a golden window of clean, powerful surf.

First up, the standout. Cobblestones is a solid reef break, and it’s our only game in town. The water is sitting at 66°, which is a touch warmer than normal for this time of year, so you might get away with a thinner suit.

The first couple of days are rough. Thursday (27th August) is a mess. We’ve got a 13 ft SW swell with a 15-second period, but the wind is a fresh cross-shore from the SSE at 19 mph, making it lumpy and choppy. The wave energy is massive (6550), but it’s a write-off for paddle surfing. It’s a big, powerful, ugly lump. Thursday afternoon drops to 10 ft but the wind picks up to 22 mph, making it even worse.

Friday (28th) is still marginal. The swell drops to 8 ft from the SW, and we get a bit of a cross-offshore breeze from the SE at 12 mph in the morning, which cleans it up a little. Still, the energy is moderate (1757), and the period is 12 seconds, so it’s mushy. Not worth getting excited about.

Saturday (29th) is where it starts to get interesting. The morning sees a 7 ft SW swell with a 16-second period, a light cross-offshore wind, and the energy is building (3512). It’s clean. But the real magic is Saturday afternoon. The wind swings NE at 9 mph, going fully offshore, and the swell pumps up to 10 ft from the SW with a 17-second period. The energy is strong (5499) and the conditions are clean. This is exceptional for experts, but at 10 ft and a long period, this is a big, powerful wave. It’s going to be perfect for the reef, but it’s NOT for beginners. The long period means it’ll peel nicely at Cobblestones.

Sunday (30th) morning is the absolute peak. We’ve got an 12 ft SW swell, a 17-second period, and a light offshore breeze from the NE at 6 mph. The energy is huge (6797), and it’s clean. This is the best on offer. If you can only paddle out once, this is it. Sunday afternoon the wind goes cross-shore, and the swell drops slightly, but it’s still a solid 10 ft.

Then the wheels fall off. From Monday (31st August) through to Friday (4th September), the wind goes onshore or cross-onshore, with speeds from 16 to 19 mph. The swell is still massive – 13 ft to 15 ft from the SW – but with that wind, it’s just a washing machine. The energy is through the roof (over 7000 at times), but it’s pure whitewater. The setup looks more interesting for kite surfing than paddle surfing.

The second week is a mixed bag. Saturday (5th September) and Sunday (6th) see the swell drop to 7 ft to 10 ft, but the wind is still cross or cross-on, keeping it choppy. Not great.

Then, on Monday (7th September), we get another window. The morning is magic: a 13 ft SW swell with a 15-second period, and the wind is light offshore from the ENE at 6 mph. The energy is massive (5984), and it’s clean. This is another expert-only session, but it’s a beauty. The afternoon goes cross-on, so get in early.

The rest of the second week is a slow fade. Tuesday (8th) and Wednesday (9th) are onshore or cross-onshore, with the swell dropping to 6 ft to 8 ft. The wind gets strong on Thursday (10th), with a 28 mph cross-on or onshore breeze, making it unsurfable. The last few days (Friday 11th) are back to big, onshore slop.

So, the call is simple. The Saturday (29th August) afternoon and Sunday (30th August) morning are the clear standouts: clean, offshore winds, big SW groundswell, and a long period. If you’re an expert, you’re in for a treat. The Monday (7th September) morning is another promising window, but it’s further out, so keep your fingers crossed. For everyone else, there’s a lot of waiting around for the wind to behave.

Rusty.
