Cobblestones Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it.

We’ve only got one spot on the radar for this stretch, and it’s a solid one, but it’s going to take some patience and a keen eye on the wind. Cobblestones is a reef break, advanced only, and it’s going to be serving up some serious power over the next couple of weeks. The water temp is sitting at 64.6°F, which is about 1.8°F warmer than usual for this time of year, so it’s a touch on the mild side.

The outlook starts with a bang on Monday, September 14th. We’ve got a hefty 11.5ft to 13.1ft SW groundswell rolling in with a 14-second period. The combined energy is pumping hard at 5483, so that’s some serious grunt. The wind is a cross-off from the ESE, so it’ll be clean, but the conditions are labelled as marginal, likely due to tide. This is big, powerful reef stuff, over 8.2ft, so it's strictly for the experienced crew.

Tuesday, September 15th, is the standout. The morning session is where it’s at. The swell drops a touch to 9.8ft from the SW, still a 14-second period, and we get a beautiful offshore wind from the ENE. It’s described as “excellent surf conditions for experienced surfers,” and I’m calling that the pick of the whole forecast. The energy is still massive at 4216. This is the one to point your board at. The afternoon sees the wind swing to a light cross-shore, making it less perfect but still surfable.

Wednesday the 16th sees the swell start to ease. The morning has 6.9ft SW swell with a 13-second period and a cross-off breeze. It’s cleaner in the afternoon with 5.2ft and a light cross-off, but the wind is a bit more onshore, so it’s not as crisp.

Thursday the 17th is a write-off. The wind cranks up from the NNW, hitting 18.6 mph, creating a messy cross-chop. The swell is still 4.9ft to 5.2ft, but the quality is poor, with a score of 0 for the afternoon.

Friday the 18th brings a new pulse of swell. The morning has 7.9ft WSW swell with a long 15-second period and a light cross-shore, but it’s marginal. The afternoon is a no-go with rain showers and a strong 24.9 mph southerly wind making an absolute mess of things, despite a 9.8ft, 16-second groundswell and energy of 5372.

The weekend, Saturday the 19th and Sunday the 20th, is a washout. Strong onshore winds from the west dominate, with 9.8ft to 11.5ft of SW swell. The energy is there, but the wind is howling onshore, making it unsurfable.

The start of the next week, Monday the 21st and Tuesday the 22nd, is more of the same. Westerly winds, rain, and messy conditions. The swell holds around 8.2ft to 9.8ft, but the quality is poor.

We get a slight reprieve on Wednesday the 23rd. The wind drops to almost nothing, with a light cross-on from the SW, and we have a 9.8ft SW swell with a 14-second period. It’s still marginal, but at least it’s clean-ish. The energy is still strong at 3894.

Thursday the 24th is similar, with light winds and 9.8ft SW swell, but the wind is onshore, so it’s not great.

Now, look ahead to Friday the 25th. We get a massive spike. The morning sees 13.1ft SW swell with a 16-second period, but the wind is onshore and strong. The afternoon gets even bigger, with 16.4ft SW swell and a 16-second period, but a fresh 21.7 mph cross-onshore wind makes it a complete mess. The energy is off the charts at 13015, but it’s not for paddling.

Saturday the 26th is interesting. The swell eases a bit to 13.1ft to 14.8ft, still with a very long 17-second period. The wind swings to a cross-shore from the south, and while it’s still a bit lumpy, the energy is still huge at 13120 in the morning. This is expert-only territory, and the long period will make it wall up at a reef like Cobblestones. This is a promising day for the big-wave chargers, but the wind isn’t perfect.

Sunday the 27th sees the swell drop back to 9.8ft from the SW with a 15-second period and a cross-off breeze, which is clean. It’s a decent option after the big days.

The final few days, Monday the 28th and Tuesday the 29th, see the swell drop off significantly. Monday has 9.8ft but with a shorter 12-second period and onshore wind. Tuesday starts with a tiny 5.2ft and ends with a massive spike to 18.0ft from the SSW, but with a strong onshore wind, so it’s another day of messy, powerful surf.

Overall, Tuesday morning the
