Alright folks, Rusty here, looking at what’s shaping up for our little slice of paradise. It’s a bit of a mixed bag, but there are some serious standouts if you know when to paddle out.
We’re kicking off this Sunday, the 12th of July, with some solid swell, but the wind's off its game. It’s a cross-onshore breeze, making things choppy. For a place like Cobblestones, this is more about watching the ocean flexing its muscles than scoring clean rides.
However, look at Monday the 13th. That morning session is where it’s at. The wind drops to a light breeze, and we’ve got a solid 13 feet SW groundswell rolling in. The energy is pumping at (7227). The cross-onshore wind is light, so the face should be holding up. This is for the advanced crew only – this much power isn’t for beginners.
The real gold, though, is what’s coming. Keep your eyes on Sunday the 19th. The forecast shows a 13 feet SW swell, period around 14 seconds, and the wind is set to be glassy, with an easterly offshore drift. The whole morning is going to be clean. The wave energy is strong at (5800). This is an expert-level playground, but for those guys, it will be exceptional.
Stick with me. The following Monday, the 20th, also looks promising. We’ll have a moderate offshore wind from the ENE holding the 10 feet SW swell up nicely. It’s a little less juice than the weekend, but still a very solid session.
We do hit a rough patch mid-week. Wednesday the 15th through Saturday the 18th is going to be messy with strong winds and rain. Saturday the 18th sees a massive 16 feet swell, but with a howling onshore wind, it’s going to be a washing machine. Even the big swell on Wednesday the 22nd (18 feet SW) comes with strong offshore winds, making it too big and dangerous even for experts.
So for the best of the best: Sunday the 19th is your standout. Glassy conditions, a solid 13 feet SW groundswell. Get your crew ready for that one.
Stay safe out there.
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.
