The Lowdown

Alright, let's get into it.

The long-range picture for Cobblestones is a real mixed bag. We’ve got a serious run of solid swell coming through, but for a lot of the time, the wind is going to be all over the shop. It’s not going to be a simple pick-and-choose forecast, this one. You’re gonna have to be picky about when you paddle out. We’re looking at a few days of nothing much to start with, then a proper window of opportunity, but you gotta be ready to move when it’s good.

The first real standout is Monday the 14th. After a weekend of onshore slop and lumpy conditions, the wind finally drops out clean. We’ve got a 13ft SW groundswell pushing in with a period of 14 seconds and the energy reading is a hefty 5713. That’s a proper, powerful swell. The morning looks glassy, which for a spot like this is an absolute gift. This is big, expert-level surf. The water temp is sitting at 64°F, which is about average for the time of year. If you’re an experienced surfer, this Monday morning is as good as it gets in this window. It’s a reef break, and it’s consistent, so it should be holding that energy well. This is the one to circle. The wind will swing onshore by the afternoon and chop it up, so make the most of the morning.

Before that, the early part of the week is a write-off. A poor weekend with strong cross-onshore winds and lumpy conditions will have the place looking messy. There’s plenty of swell, but the wind will ruin it. It’s not worth the effort.

After that Monday gem, we slide back into mediocrity. Tuesday the 15th and the rest of that week have more swell, but the winds are all over the place and the quality drops away. It’s not going to be clean. There’s a lot of cross-shore and onshore conditions, so the surface is going to be chopped up.

Now, the second week. We’re looking at another potential pulse around the 19th and 20th, but it’s far out and the long-range forecast is less certain. There’s a big swell showing for the 19th with some seriously strong energy readings, but the wind is on it and it looks like a complete mess. It could be a washing machine out there.

The end of the run, around the 22nd, shows another big pulse of SW groundswell, but again, the wind is just going to be too strong to make it any good for a paddle. If this holds, that’s the kind of energy that might be more interesting for the kite crew than us surfers. We’ll have to see how it plays out.

So, the bottom line: it’s all about getting out on Monday morning the 14th. That’s the standout window. The rest of it is either onshore slop or just too messy to get excited about.

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.
