Cobblestones Surf Forecast and Surf Report

Alright crew, Rusty here. Let’s have a look at what’s coming down the line for Cobblestones.

We’ve got a solid run of surf ahead, but the quality is a real mixed bag, so you’ll need to pick your moments. The week starts with some serious size but messy conditions, and then we get a beautiful window of clean, powerful swell before it all goes a bit wild again.

The first real action kicks off Sunday, September 6th. There’s a big, powerful SW groundswell rolling in, with a period of 13 seconds and a combined energy reading of 5913, which is moderate. The wave height is a meaty 13 feet. Problem is, the wind is a fresh cross-shore SSE breeze at 19 mph, so the ocean will be lumpy and a bit of a mess. This is really for the experienced crew only. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year.

The quality picks up noticeably on Monday, September 7th. The morning session is the standout for the early part of the week. We’ve got a clean 12 feet SW groundswell, with a solid 16-second period, and the energy is moderate (6877). The wind is a gentle cross-offshore breeze from the SE at 9 mph, which will have the waves looking really clean. This is exceptional surf for the experts, but it’s a big swell, so it’s not a beginner’s day. The afternoon gets a bit bumpy again as the wind swings and freshens.

Tuesday, September 8th, is another good shout. The morning offers a clean 13 feet SW swell (16 seconds, energy 8462), with a moderate cross-offshore breeze. The afternoon holds up nicely too, with a clean 13 feet WSW swell and a lighter breeze. The conditions are much better than the weekend, with the wind cleaning things up.

The cleanest, most user-friendly window of the whole period looks like Wednesday, September 9th. The morning offers a 10 feet WSW swell with a 15-second period, and here’s the kicker: the wind is offshore from the ENE at 16 mph, cleaning the lineup perfectly. The energy is moderate (4551). The afternoon session is even better for light winds, with a 10 feet SW swell and a light offshore breeze. This is excellent surf for experienced surfers. The swell is still over 8 feet, so it’s not for the groms, but for anyone who can handle it, this is the best day of the first week.

From Thursday, September 10th, the swell starts to drop, and the quality takes a dive. The winds become more cross-shore or cross-onshore, and the wave shapes get weaker. Friday through the weekend and into the next week is a write-off, with strong cross-onshore winds and choppy, poor conditions. The swell sticks around, but the wind ruins it. This stretch from Thursday afternoon through to Monday, September 14th, is a real gap for good surf.

The second week gets a bit more interesting, but it’s a heavy-hitter. From Thursday, September 17th, we see a massive swell event. The energy readings go through the roof, hitting four and five-digit numbers like 15328 and 22601, which is very strong. The wave heights blow up to 20 feet or 21 feet, but the wind is mostly onshore or cross-onshore, making it messy and dangerous. The tide and wind are noted as favorable at times, but the swell is simply too big for this break. This is expert-only territory, and honestly, it looks more like a kite-surfing day than a paddle-surfing day for most. The 20th of September offers a 21 feet SW groundswell with a 16-second period, but the cross-shore wind will create a big chop. There’s a chance of a clean-up set, but it’s a wild one.

The best bet for the whole outlook is Wednesday, September 9th. The morning offers a clean 10 feet WSW swell, an offshore wind, and a long period, making for the best shaped, cleanest waves of the run. The Monday morning, September 7th, is a close second.

Rusty out.
