Alright gang, Rusty here, looking at Cobblestones. This is a reef, and it’s for the advanced crew only. Water temp is sitting about 67°F, which is normal for right now.
We’re looking at a long run of big, powerful SW groundswell, but the wind is gonna be a pain early on. We gotta let the first few days pass before we hit the real jackpot.
The biggest standout is going to be Wednesday, July 8th in the morning. The ocean is dead flat, glassy calm. We’ve got a 12ft swell from the WSW with a super long period of 17 seconds. The energy is massive (6447). This is serious groundswell – only for experts – but the conditions will be absolutely perfect.
Another absolute beauty is Monday, July 13th. The morning has clean 10ft SW swell at 16 seconds (4310 energy) with a light offshore breeze. Then it gets even better for the afternoon: 8ft SW swell at 15 seconds (2901 energy) and completely glassy. That afternoon session is going to be a dream for any advanced surfer.
Saturday, July 4th, has a solid 10ft SW swell at 17 seconds (5166 energy), but the cross-offshore wind is blowing 30 km/h, so it’s not as clean. The afternoon drops a bit in size but stays windy.
A bit later, around July 10th, the swell gets huge at 16ft, but with strong onshore winds. That’s proper kite-surfing territory, not for paddling.
From July 14th onward, the swell settles to 5ft to 8ft with moderate cross-off winds. It’s okay, but nothing compared to that 8th and 13th. The end of the run, around July 18th and 19th, tries to build some 16ft WNW windswell, but the wind is onshore and it’s a total write-off.
If you want the best, you know the dates: Wednesday morning, July 8th, and Monday, July 13th (that glassy afternoon). Those are the ones.
Rusty.

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.
