Cobblestones Surf Forecast and Surf Report

Right then, folks, Rusty here. Let’s have a proper look at what’s coming our way.

We’ve got one spot on the radar for the next couple of weeks, and it’s a proper big-wave reef setup. Cobblestones is an advanced, exposed reef break that loves a solid SSW groundswell, and it’s consistent. The water’s sitting at 65°, which is about a degree and a half warmer than usual for this time of year, so that’s a nice little bonus.

The forecast kicks off on Monday, September 7th, and by gum, we’re straight into it. Monday morning is looking like a standout. We’ve got a solid 12 ft swell from the SW, with a very long period of 16 seconds, and a light, cross-off breeze from the SSE. The energy is huge (6877), and the conditions are described as exceptional. This is proper groundswell; it’s going to be powerful and clean, but only for the experts. That long period will make for some memorable, heaving walls at that reef, but the size and power mean it’s strictly for the skilled crew.

The wind holds for the rest of the week, but the size and quality vary. Monday afternoon sees the wind pick up to a fresh 19 mph cross-shore, making it lumpy and messy. Tuesday the 8th is a cracker, though. Morning and afternoon both have a solid 13 ft SW swell with that long 16-second period, and a clean cross-off breeze. The energy is pumping (8781), and the afternoon session is glassy clean. That’s a top-tier window for the experienced.

Wednesday the 9th still has a 10 ft swell, but a fresh 19 mph offshore on the morning makes it a bit wild, and the combined energy drops to 3926. It’s still clean, but a handful. Thursday the 10th drops to 7 ft, but Thursday afternoon is a real treat: a glassy 7 ft swell from the WSW with a 15-second period. That’s a magic window for a more manageable session.

The first real standout of the whole period, though, is Monday, September 14th. After a rough, windy weekend, Monday morning brings a clean 10 ft SW swell with a 14-second period. The wind is a light cross-off from the NNE, and the energy is a solid 3531. The conditions are described as excellent for experienced surfers. That’s the one to circle.

After that, things get bigger and wilder. From the 17th onwards, we’re looking at serious, heavy swell. By Friday, September 18th, we’re seeing 18 ft swells with energy readings over 15,000. That’s massive. Even if the wind is favourable, the break is predicted to be too big. This is truly expert-only territory, and even then, it’s pushing the limits. The final weekend of the 20th and 21st of September has giant 16 ft to 18 ft SW groundswells, but with a cross-off or cross wind, the energy is astronomical (18,000+). The setup looks more interesting for a tow-in or kite session than a standard paddle.

So, to sum it up: the best, most accessible surf for the strong paddler is Monday, September 14th. For the absolute top-tier, biggest, cleanest wave, Tuesday, September 8th is your date. Get on it.

Rusty.
