Cobblestones Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a wild, long-range outlook for Cobblestones, and it's a bit of a rollercoaster. This is a proper advanced reef break that picks up a ton of energy, but the wind is going to be the gatekeeper for most of the next two weeks.

The ride starts off rough. Thursday the 10th and Friday the 11th have a big, long-period swell pushing in from the WSW with wave energy reading (2327 to 4741), but the scores are low. The wind is cross-off, which keeps things clean, but there’s a note of “questionable tide conditions” holding it back. That 10ft swell on Friday afternoon with an 18-second period is a beast, but it’s also borderline for this spot. Saturday the 12th through Sunday the 13th is a write-off for paddling—10ft to 12ft of WSW swell but with strong onshore winds making it choppy and blown out. Combined energy is peaking (5659), but the quality is “poor.” If you’re into kite surfing, that weekend setup might be your jam, but for a surfboard, it’s a hard pass.

Now, here’s where it gets interesting. Monday morning, September 14th, is your standout window. The forecast pulls a 180. A 13ft SW swell at 14 seconds is pumping in, but the magic is the wind: a glassy 3 mph offshore breeze from the NE. That’s the recipe for perfection at this exposed reef. The combined energy is massive (5891), but the quality is “exceptional for expert surfers.” The crowd profile says “sometimes” here, so expect a few heads out, but with that size and power, only the crew will be out. The water temp is about average for the time of year, no real anomaly to speak of.

Monday afternoon sees the wind swing onshore, so the window is small. The session is Monday morning, first light.

The rest of the first week is a mix. Tuesday and Wednesday have moderate swell (8ft to 10ft) but the wind is cross or cross-onshore, making it lumpy. Thursday the 17th has a 7ft swell with a strong N wind, but the size is dropping and the period is shortening. By the 18th and 19th, it’s back to strong onshore winds and blown-out conditions.

The second week looks more intriguing. Sunday, September 20th, has an 12ft SW swell with a light NNW wind making for clean conditions (4270 energy), but the wind is cross-shore, not offshore. It’s surfable for the experienced, but not the standout. Then we hit a rough patch from the 21st to the 23rd with onshore gales and rain. But then, Thursday morning, September 24th, has a promising window: a 6ft SW swell with a light offshore N wind and excellent conditions for experienced surfers. The combined energy is lower (1243) but the quality is there.

Friday the 25th looks promising long-range with an 8ft SW swell and 18-second period, but the wind is onshore, so stay tuned.

In short: The best bet on offer is Monday morning, September 14th – big, clean, and powerful at Cobblestones. Get on it if you’ve got the skill. The secondary call is Thursday morning, September 24th – smaller but clean. The rest is a waiting game for wind.

Stay frothy,
Rusty
