Cobblestones Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s break down what’s coming for the only spot on the menu, Cobblestones. This is a reef break that needs a solid SW groundswell, and it’s for the advanced crew only.

The first week has a bit of everything, but the real standout mornings are Monday, September 14th, and Thursday, September 24th.

The water is 65°, which is a touch warmer than normal for this time of year.

We start with a bang on Wednesday the 9th. A solid 10ft SW groundswell is hitting, with a very long period of 15 seconds, and the wind is a glassy offshore from the ENE. The energy is pumping (4064), and it’s clean. This is prime Cobblestones, but the swell is over 8ft, so this is for the experts only. The morning is the pick.

Thursday the 10th sees the swell drop to 7ft, with a cross-offshore wind at 15 mph. It’s clean, but the energy is dropping (2327). The afternoon goes lighter, with a cross-shore wind, so it’s a bit average.

Friday the 11th has a 7ft swell with a 16-second period, but a fresh cross-offshore wind at 18 mph keeps it bumpy. The energy jumps back up (3576). The afternoon gets bigger, 10ft, with a period of 18 seconds, but the wind is still cross-offshore. The energy is massive (4741), but the wind will make it a battle.

Saturday the 12th and Sunday the 13th are a wash. The wind goes onshore, blowing the big 10ft to 12ft swells into a choppy mess. The energy is huge (up to 5647), but the conditions are poor.

Monday the 14th is the first big standout. The morning brings an 12ft SW swell, period of 14 seconds, and a light cross-offshore breeze from the NNE. The energy is massive (5305), and the conditions are exceptional for experts. The afternoon gets a bit onshore, so get it early.

The rest of the week from Tuesday the 15th to Friday the 18th is a grind. The swell hangs around 7ft to 10ft, but the wind is mostly cross-onshore or cross-shore, making it choppy. The energy is moderate to strong (1694 to 2978), but the quality is not there. Friday morning the 18th has a near gale wind, so that’s a no-go.

Saturday the 19th sees a massive jump, with a 16ft swell, but the wind is onshore, making it a total mess. The energy is 11890. The afternoon cleans up a bit with a cross-onshore, but it’s still huge at 15ft.

For the second week, the run from Sunday the 20th to Tuesday the 22nd is dominated by huge, dangerous swell. The 21st and 22nd have swells of 15ft to 18ft, with periods of 17 seconds, and the energy is off the charts (over 11968). The wind is cross-onshore or cross-shore, so it’s a wild, lumpy, and dangerous zoo. The forecast says it’s too big for this break.

Wednesday the 23rd is a letdown, with the swell dropping to 12ft but the wind is onshore again.

Then we get the second standout. Thursday the 24th. The morning brings an 12ft SW groundswell, period of 15 seconds, and a glassy offshore wind from the ENE. The energy is strong (5894), and the conditions are exceptional for experts. The afternoon gets a cross-onshore, so make it a dawn patrol.

For the overall picture, if you’re an advanced surfer, the mornings of September 14th and September 24th are your best bets for clean, powerful Cobblestones. The crowds are “sometimes,” so you might have a few others out, but it won’t be a circus.

Rusty.
