Cobblestones Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into the Cobblestones outlook. This is a heavy, exposed reef, so it’s one for the advanced crew only. The swell energy is going to be massive, so we’re calling this one for the experts.

We’ve got a solid run of surf starting from Tuesday the 8th of September. The water temp is about average for the time of year, so nothing wild there. The early-morning session on Tuesday has a clean 13.1ft SW groundswell, with a very long 16-second period, pumping out strong wave energy (8888). The wind is a cross-off from the ESE at 12 mph, which will keep the faces tidy. This is a serious standout for the experienced surfer. The afternoon holds, with a 13.1ft WSW swell and a cross-off breeze, still exceptional quality.

Wednesday the 9th brings a smaller but still chunky 9.8ft SW swell, with an offshore ENE wind at 16 mph in the morning. That’s a clean, powerful combo, though the energy is still high (4187). The afternoon glass-off with a 3 mph cross-off from the east is a dream setup for a late session.

Thursday the 10th sees the swell drop to 6.9ft, but the afternoon is pure magic. The wind goes glassy, just a slight air from the WNW, and the swell is a clean 6.9ft SW with a 15-second period – that’s a very long period groundswell, perfect for a reef like this. The energy is moderate (2232). This is your best bet for the lighter days.

Into Friday the 11th, the swell drops to 5.2ft but the period jumps to 19 seconds – that’s incredibly long. Morning is clean with a light cross-off, but the afternoon gets a bit tricky with a cross-shore and 9.8ft swell. The energy is still strong (5177).

Saturday the 12th is a write-off. Strong cross-onshore winds and messy surf. Sunday the 13th is also poor with onshore winds and rain. This is a dead zone for quality surfing.

Monday the 14th brings a 11.5ft WSW swell with a 14-second period. The wind is light and cross, so the wave quality is marginal but surfable. The energy is high (5499). This is a go for the experienced, but conditions are not perfect.

Tuesday the 15th is onshore again, so look elsewhere. From Wednesday the 16th through to the end of the period, the winds turn mostly cross-onshore, and the swell stays big, but the quality is poor. The standout remains the Tuesday morning and Wednesday afternoon of the first week. The real highlight, though, is the Thursday afternoon glass-off session – with the wind dropping to nothing, a 6.9ft very long-period swell, and the reef doing its thing, that’s the one to circle on your calendar.
