Cobblestones Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what’s headed our way for Cobblestones. This is a solid, exposed reef that needs a good south-west groundswell to light up, and when it does, it’s a beauty for those who know what they’re doing. The water’s sitting at 65°, which is a touch warmer than we usually get this time of year – nothing crazy, but you’ll notice it’s pleasant.

We’ve got a messy start, though. The first solid swell hits on Friday the 4th of September, with a 16ft SW swell and a very long period of 14 seconds. The wave energy is pumping hard (10769), but the wind is a gentle onshore breeze from the WSW, and the report says marginal surf conditions. It’s going to be big, powerful, and a bit of a battle. Not the one to get excited about for clean waves.

Saturday the 5th is a write-off with strong cross-shore winds and rain, dropping to an 12ft SW swell. Sunday the 6th is still messy with fresh cross-shore winds, even though the swell is a solid 15ft SW. The energy is still high (7424), but it’s lumpy.

Now, Monday the 7th is where we start to see the light. The morning is clean with a gentle cross-offshore breeze from the SE, and an 12ft SW groundswell (16 seconds). The energy is still strong (6945), and the conditions are clean. This is a solid, powerful wave but the wind is finally cooperating. Tuesday the 8th is the big standout. Morning and afternoon both have clean conditions, with a moderate to gentle SE breeze, and a 13ft SW swell (16 seconds). The energy is very strong (8122 and 8381), and the scores are high. This is the best of the first week. The swell is a touch over 8ft, so it’s strictly for experts, but the shape and power will be incredible.

Wednesday the 9th is another good one. Morning sees a light offshore NE wind at 16 mph, with a 10ft SW swell (15 seconds). The conditions are excellent for experienced surfers. The wind swings cross-offshore in the afternoon, but it’s still clean.

The end of the first week and into the second week gets a bit mixed. Thursday the 10th drops to a 7ft SW swell, but the wind is clean. The 11th sees a new pulse of WSW swell, with a very long period of 18 seconds on Friday afternoon, but the wind is cross-offshore. It’s surfable, but not a standout.

The weekend of the 12th and 13th is a total mess – strong cross-onshore winds and rain, with big 16-18ft swells. Forget about it.

But then, Monday the 14th of September is the absolute standout of the whole forecast. Morning brings an 18ft WSW swell (13 seconds), with a light offshore breeze from the NE at 6 mph. The energy is huge (10041), and the report says exceptional surf for expert surfers. This is a massive, clean, powerful reef swell. It’s dangerous, but it will be the best session of the whole run if you’re brave enough.

The rest of the second week has some fun, smaller windows. The 16th of September afternoon looks good with an 12ft WSW swell, clean and a gentle breeze. The 17th morning has a 15ft SW swell with clean cross-offshore winds, but it’s very windy. The 18th and 19th are mostly blown out by onshore winds.

So, the pick of the week is crystal clear: Tuesday the 8th of September for the combination of size, power, and clean conditions. And if you’re an expert looking for a challenge, Monday the 14th of September is the one to circle on the calendar, but it’s a long way off, so keep an eye on the forecast.

Rusty.
