Table - best surf conditions forecast for Cobblestones over the next 16 days.
Alright, folks, Rusty here. Let’s talk about Cobblestones. We’ve got a wild 16-day run on the cards, and if you’re an experienced surfer, you’re in for a treat. This is a solid, exposed reef break for advanced crew only, and it’s gonna be pumping.
Water temp is sitting at 67°, about average for this time of year, so no surprises there.
The action kicks off proper on Wednesday, July 8th. We’re looking at a massive, clean 12 ft groundswell out of the WSW with a very long 16-second period. The energy is off the charts, over 6000, and with that glassy 3 mph north wind, it’s gonna be pristine. If you can handle it, this is the standout moment early.
Thursday and Friday are still big, with 10 ft and 5 ft respectively, but the wind swings onshore or cross-shore, making it a bit of a battle. Saturday the 11th shows 8 ft swell with a cross-shore wind, which is okay. But the real gold comes back.
Monday morning, July 13th, we’ve got 12 ft of straight-on WSW swell with a 16-second period and only 6 mph wind. It’s going to be a heavy, racy wave. Then Tuesday, July 14th is an absolute gem. You get a clean 10 ft swell from the SW with a 15-second period and light offshore winds from the ENE, glassy in the afternoon. This is the other true standout for the experienced – a day to circle on the calendar.
The middle of the second week gets messy with rain and strong winds. By Sunday, July 19th, the swell absolutely detonates, hitting 21-25 ft. The energy numbers are staggering, over 15000, but the wind is onshore and it’s just too big for this break – expert-only territory, and frankly, dangerous.
It settles a bit into the 21st and 22nd with 16-20 ft swell, but the wind is cranking, and the quality drops hard. The last three days, the 21st to the 23rd, are a write-off with rain, strong winds, and poor conditions.
So, for the best of the best: forget the second week’s chaos and lock in Wednesday morning, July 8th, and Tuesday, July 14th. That’s your clean, powerful swell with light winds. Crowds are possible at Cobblestones, so get there early.
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.
