Alright folks, Rusty here. We’ve got a solid run of swell lining up at Cobblestones, but Mother Nature isn’t making it easy for us. This is a spot for advanced surfers only, so beginners should sit this one out. Water temp is about 67°, which is pretty normal for this time of year.
The real standout window kicks off on Monday, July 6th. We’re looking at waves around 12 feet from the WSW with a 15-second period, building to 13 feet in the afternoon. The combined energy is hefty, and the wind is cross-offshore from the SSE, keeping things clean. That’s where it gets prime—Tuesday, July 7th morning is a top contender: 12 feet from the SW, a 16-second period, and light cross-offshore winds from the SE making it glassy. That’s the pick of the early week.
But Wednesday, July 8th morning might just steal the show. We’ve got 12 feet from the WSW, a very long 17-second period, and a light cross-offshore breeze from the North. The water will be clean, the energy is pumping, and this is exceptional surf for experts. For a reef break like Cobblestones, that long-period SW groundswell will wrap in and offer proper waves.
Things go downhill from Thursday, July 9th with onshore winds and lumpy conditions. The weekend of the 11th gets ugly, with waves hitting 18 feet but the wind turning to a messy cross-onshore chop. That’s kite-surfing conditions, not paddle surfing.
A second small window opens around Monday, July 13th and Tuesday, July 14th. On the 14th, the morning brings 8 feet from the SW under offshore ENE winds, and by the afternoon it turns dead glassy with 8 feet from the SW. It’s not huge, but it’s clean and rideable for experienced surfers.
To sum it up: Monday, July 6th morning is a fantastic start, but Wednesday, July 8th morning is the standout—big, clean, and groundswell perfection. If you’re an expert and you can get out there, that’s your session.
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.
