Howdy, Rusty here again. Let's talk about what's brewing at Cobblestones.
First thing you need to know: this ain't a spot for the faint of heart over the next week. We've got some serious south-west groundswell lining up, big and mean. The water's sitting right on 67°, which is what you'd expect for this time of year.
The first real standout day is Monday the 6th. We're looking at 12ft to 13ft of WSW swell with a long 15-second period. The energy is massive – readings in the "strong" range (5896 to 6903). Skies are clear and a light SE cross-off breeze will keep it glassy. At over 8ft, this is strictly for experts. The swell direction is a perfect match for the reef.
Wednesday the 8th of July is another absolute gem. A solid 12ft of WSW swell, 17-second period, and a light ENE offshore wind at only 6 mph in the morning. That's about as perfect as it gets for a big wave session. The energy is sky-high at (7136). This is exceptional, but you need to be in the water early before the wind swings onshore.
The 12th of July also looks like a winner, especially the Sunday morning with 8ft of SSW swell, a 13-second period, and clean offshore ENE winds. That's a little more manageable but still a serious wave. The following days, the 13th and 14th, hang onto good 7ft to 10ft groundswell with consistent cross-off breezes. It's a long run of solid surf, but the very best of it is definitely that Monday and Wednesday.
The first week is stacked. After some messy conditions on Saturday the 4th and Sunday the 5th with rain and gusty cross-shore winds, it cleans right up for that Monday. The second week, around the 15th and 16th, the swell drops to about 6ft to 7ft, but it stays clean with offshore to cross-off winds. Good waves, just not as heavy. The very end of the forecast, around the 19th, gets a bit lumpy again.
Cobblestones is a reef that loves a south-southwest swell, and this forecast is mostly delivering that. Keep an eye out for crowds, as it can get busy here on the good days.
Bottom line: the 6th and the morning of the 8th are your absolute best bets. Be there or be square.
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.
