Cobblestones Surf Forecast and Surf Report

G’day, Rusty here, and I’ve got a look at what’s coming up for Cobblestones. This is an advanced reef break that loves a good SSW swell, and it’s looking like a wild ride for the next couple of weeks, but only if you pick your moments. The water is sitting at 65.5°F, which is a touch warmer than normal for this time of year—nothing crazy, but you’ll notice it.

The first real surf on offer starts Wednesday the 2nd of September, but it’s a rough start. Wednesday morning brings a solid 11.5ft SW swell, with a 13-second period, but the wind is howling onshore from the SW at 16 mph, and the combined energy is massive at 4447. The conditions are poor, and the score is a flat zero. Wednesday afternoon isn’t much better—11.5ft SW swell, cross-on wind, and the energy is still high at 4332. It’s marginal at best, with choppy, messy waves. Thursday the 3rd builds to 13.1ft SW swell with a 15-second period, but the wind is cross-on and fresh at 19 mph, energy at 6607, and it’s a total write-off. Friday the 4th gets even bigger—18.0ft WSW swell on Friday morning, but the wind is cross-on at 16 mph, and the energy is through the roof at 10100. Still poor. Friday afternoon, however, brings a shift: the wind switches to onshore from the WSW at 9 mph, the swell drops to 16.4ft from the WSW with a 15-second period, and the energy hits 12490. The score jumps to a 7, and it’s described as marginal due to tide, but the wind is light and onshore, so it’s actually clean. That’s a standout window for the brave—big, powerful waves, but the period is long, so this reef will handle it well.

The weekend is a mess. Saturday the 5th has a 11.5ft SW swell with a 14-second period, but the wind is cross-on and fresh at 22 mph, and the energy is 4842. Then Saturday afternoon is blown out with a 16.4ft SW swell and 34 mph near gale cross-onshore winds. Sunday the 6th is better: the swell is 14.8ft from the SW with a 13-second period, the wind is cross-shore at 19 mph, and the energy is 8367. It’s marginal, scoring a 6, with lumpy cross-chop. Sunday afternoon sees a 16.4ft SW swell with a very long 17-second period, cross-shore wind at 16 mph, and energy at 14334, scoring a 7. The waves will have power, but the long period might make the reef a bit tricky.

Now, the real gem is Tuesday the 8th of September. Tuesday morning is absolutely the pick of the whole forecast. The swell is 13.1ft from the SW with a 16-second period, and the wind is cross-offshore from the ESE at 6 mph, light and clean. The energy is 8429, and the conditions are described as exceptional for expert surfers, scoring a 9. This is the one to circle—big, clean groundswell, light offshore wind, and the reef will be firing. Tuesday afternoon drops to a 7, with a gentle cross-shore breeze, but still decent.

Wednesday the 9th through Thursday the 10th sees the swell dropping to 9.8ft and 8.2ft, with cross-offshore or cross-shore winds, but the scores are low (2-4). Not worth paddling out for.

Friday the 11th brings another pulse: 14.8ft WSW swell with a 17-second period, but the wind is onshore at 16 mph, energy at 11273, and it’s poor. Friday afternoon is 16.4ft WSW, cross-on wind, scoring a 6—marginal and choppy.

Saturday the 12th to Sunday the 13th is small stuff, 8.2ft to 11.5ft, with light winds and scores of 3-5. Nothing to get excited about.

Monday the 14th sees a 14.8ft WSW swell with a 15-second period, cross-shore wind at 16 mph, energy at 8660, scoring a 7. It’s moderate and choppy, but worth a look.

Now, the last week gets wild. Tuesday the 15th of September: the swell hits 26.2ft from the WSW, with a 14-second period, and the energy is a staggering 25277. The wind is light cross-onshore, but the comment says it’s too big for this break and scores an 11. That’s expert-only territory, and even then, it’s a monster. Wednesday the 16th is still massive—19.7ft to 18.0ft WSW swell, energy up to 20838
