The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for Cobblestones. This is a solid reef break that needs a fair bit of size and a good direction to fire, and it looks like the coming weeks are going to deliver in a big way.
We kick things off on Wednesday the 22nd of July with the first real action. A solid SW groundswell is pushing through at about 12ft with a long 14-second period. The water is sitting at a touch warmer than normal for this time of year at 67°, so you might get away with a slightly thinner wetsuit. The combined energy is very strong at 4932. With a light SE cross-off breeze, conditions are clean and this is excellent surf for the crew who know what they're doing.
The surf hangs around through Thursday the 23rd and Friday the 24th, but it's a bit of a mixed bag. Thursday morning has a decent 8ft SW swell, but the vibe is a little marginal due to the tide or winds. The best window on Friday looks to be the afternoon, with clean 6ft SW swell and light offshore NNE winds. Saturday the 25th has a similar size but gets a bit wind-affected.
We get a proper pulse of energy moving in on Sunday the 26th of July with a 10ft W swell, but the wind is howling from the WNW at 34 mph, making it a complete write-off. The next couple of days see some serious size but messy conditions. Monday the 27th brings a massive 13ft SW swell, but it’s mostly blown out.
The real standout in the first week is Tuesday the 28th of July. The swell drops back to a clean 10ft from the SW, period still a long 14 seconds, and we get a light offshore wind from the ENE. That’s Cobblestones at its finest – powerful, lined-up reef waves for the advanced surfer. The wave energy is strong at 3716, and it’s the pick of the early run.
Things get wild towards the end of the month and into August. The morning of Friday the 31st of July is the absolute highlight of the entire outlook. We’re looking at a massive 15ft SW swell with an incredibly long 16-second period. The combined energy is massive at 9542. What makes it truly exceptional is the wind – dead calm, glassy conditions. This is a proper big-wave day for experts only. Swells over 8ft, and at this size, it's in the danger zone. The offshore wind will groom it, but this is not a place for the faint of heart.
The big energy continues into the first week of August. Saturday the 1st of August sees a 15ft SSW swell, but the file says it might actually be too big for the break, even for the experienced crew. Sunday the 2nd of August has a strong 12ft SW swell with a clean offshore NE wind, another great day for experts.
Through the rest of the first week of August, the swell holds at a solid 8ft, but the winds are a bit stronger from the NNE. It’s still surfable, but the quality drops off. The final session in the window on Thursday the 6th of August sees the swell pumping again at 13ft from the SW with a very long 18-second period, but the cross-onshore wind makes it a messy, blown-out beast.
To sum it up for Cobblestones: the first few days have fun waves, but the standout is Tuesday the 28th of July for a clean, solid swell. The absolute best wave of the outlook is the glassy monster on Friday the 31st of July. After that, it remains big and powerful for those who can handle it, but the wind plays a bigger role. Keep an eye on that Friday the 31st window.
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.
