The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for Cobblestones.

First up, this is a heavy-duty reef break, and it's consistent. The water is currently sitting at 67.5°F, which is much warmer than normal for this time of year – a solid 4.1°F above average, so you can leave the thick wetsuit at home.

Right now, and for the first several days, we're looking at a massive amount of energy. While the swell direction from the SW is a good match for this spot, the size is just plain intimidating. On Saturday the 8th, we're talking a 24.6ft swell from the SW with a very long 15-second period. The combined energy is 22456 – that's not just a lot, that's a monster. With a strong cross-onshore wind blowing at 31 mph, it's blown out, dangerous, and really only for the most experienced chargers, if anyone. This setup is more interesting for kite surfing than paddle surfing. This continues through Monday the 10th, with the swell dropping slightly but still in the 16-20ft range and the wind staying messy.

We get a bit of a breather on Wednesday the 12th and Thursday the 13th. The swell drops to a more manageable 13.1-14.8ft, still with a nice long 15-16 second period from the SW. The wind goes light offshore, swinging from W to SW. This is a serious upgrade in quality. The combined energy is still moderate (around 7905-9362), but with clean conditions, these are the first real windows for experienced surfers. Thursday afternoon looks the pick of the early week with that light breeze and clean faces.

Friday the 14th is a proper standout. The swell eases to 11.5ft, still a solid SW groundswell with a 16-second period, and the wind goes light cross-off from the NNE. The water will be glassy. The combined energy is 5974 – still plenty of punch. This is exceptional surf, but make no mistake: at this size and with this power, it's strictly for experts. It's a true highlight.

Saturday the 15th and Sunday the 16th see the swell drop further, with the wind holding clean and cross-off. The waves are smaller, but the quality is still there. It's a good run. Then on Monday the 17th, the swell picks up again and the wind turns onshore, messing things up.

Looking into the second week, we get another pulse of serious size on Tuesday the 18th with a 21.3-23.0ft swell and strong cross-onshore winds – back to the big, messy stuff. But then, Wednesday the 19th and Thursday the 20th are a real gift. The swell is still a hefty 19.7-14.8ft from the WSW, but the wind flips to a light offshore from the N and NNE. The combined energy is still high (19927 on Wednesday), but it will be clean. This is the other big standout of the outlook: big, powerful, and clean. Only for experts though.

The final days from the 21st to the 23rd look like a return to strong, onshore winds and messy, oversized surf. The 23rd sees a 24.6ft swell with a 17-second period and a combined energy of 34137, but it's going to be a lumpy, choppy mess.

So, the bottom line: the first week is a story of too much size and wind, with a couple of clean windows for the experienced crew on Thursday and Friday. The second week brings another huge swell, but the standout is definitely Wednesday the 19th and Thursday the 20th, when the wind drops and the waves are big, powerful, and clean. If you're an expert, that's your window.

Information about the Cobblestones Surf forecast

The above surf forecast table for Cobblestones provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cobblestones can be found by selecting the local surf guide option on the grey menu. Our Cobblestones surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Cobblestones) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Cobblestones may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
