Cobblestones Surf Forecast and Surf Report

Alright, folks, Rusty here. We’ve got a solid run of swell on the way, but it’s not going to be an easy ride for the whole stretch. The big story is the consistent, powerful SW groundswell, but it’s going to come with a lot of wind in the early days.

The first real window of opportunity kicks off on the morning of Thursday, August 21st. The standout morning is looking like Friday, August 22nd. That’s the one you want to circle. We’ve got a 16ft swell from the WSW, but the conditions are absolute trash with a strong onshore wind. The combined energy is massive at 9915 (moderate to strong wave energy). The water temperature is 67°, which is a touch warmer than normal for this time of year.

Forget the first couple of days. Thursday the 21st is where it starts to get interesting. The morning sees the swell dropping a touch to 13ft from the WSW, but the wind swings light and onshore. It’s still a bit messy, but it's a step up. The real gold is Friday morning, August 22nd. We’ve got an 12ft SSW groundswell with a very long 15-second period, and the wind is glassy, absolutely glassy, from the NNE. That’s a rare combination. The combined energy is 5680 (moderate wave energy). Cobblestones is a reef break, which is perfect for this long-period groundswell. It’s an advanced break, and it’s consistent, so expect a few others who know the score. The crowds are listed as “sometimes,” so you might have company, but for a wave this clean, it’s worth it.

The surf stays solid through the weekend, but the wind picks up again, making it choppy and cross-onshore. The swell drops to 10ft on Saturday with a 16-second period, but it’s messy. Sunday drops to 8ft, but the wind is even stronger.

Monday, August 25th, brings a change. The wind goes light cross-offshore from the NNE, and the swell is a solid 10ft from the SW with a 13-second period. The combined energy is 3041 (moderate wave energy). The morning is described as “clean” and excellent for experienced surfers. This is a good session, but the swell is still big enough that beginners should sit this one out.

The middle of the week, from August 26th to 28th, is a write-off. The wind is howling onshore again, with a 16ft swell on the 26th that’s just blown out. The combined energy hits 13858 (strong to very strong wave energy), but it’s a mess.

The second week starts to look promising again. On Friday, August 29th, the morning is clean with a light cross-offshore breeze from the ESE. The swell is down to 6ft from the SSW with a 12-second period, and the combined energy is 1990 (moderate wave energy). That afternoon is also clean, with a 6ft SSW swell. Both are excellent for experienced surfers.

Saturday, August 30th, is another standout. The morning is glassy, with a light cross-offshore from the NNE. The swell is 4ft from the WSW with a very long 17-second period, and the combined energy is 1551 (moderate wave energy). That’s a long-period groundswell, perfect for a reef like Cobblestones. It’s going to be clean and lined up.

Sunday, August 31st, the morning is clean again with a light cross-offshore from the NNW. The swell is back up to 10ft from the WSW with a 16-second period, and the combined energy is 4184 (moderate wave energy). Another excellent session for experienced surfers.

The last day of the forecast, Thursday, September 4th, shows a clean morning with a light cross-offshore from the NNE. The swell is 8ft from the WSW with an 11-second period, and the combined energy is 2091 (moderate wave energy). The afternoon is also clean with an 8ft WSW swell. A solid way to finish the stretch.

The one true standout is the Friday morning, August 22nd, with the glassy conditions and the long-period groundswell. The other top pick is the Saturday morning, August 30th, with the 4ft, 17-second groundswell and glassy wind. Both are on the reef, so they’ll handle the long period beautifully.

Rusty.
