The Lowdown
Alright, let’s get real about the next couple of weeks. It’s a tough stretch, no two ways about it. We’re looking at a long, flat run for the most part. Don’t get your hopes up for any kind of proper swell; this is a waiting game.
The whole 16-day window is pretty bleak. We’re talking about a solid week or more of nothing worth paddling out for. The combo energy is weak, mostly in the 20s and 30s, which is just sad in brackets (34, 26, 23). The swell that does show up is tiny and short-period, not the kind of stuff that gets the heart racing. The water temp is 72°F, which is pretty normal for this time of year, so at least you won’t be freezing while you’re sitting there wondering why you came out.
The only time things look like they might even get close to interesting is around Sunday the 23rd into Monday the 24th. The energy jumps up a bit to moderate (144, 142, 229), but the wind is all over the place. Sunday is cross-shore and messy, and while Monday morning has a fresh offshore at 19 mph, it’s still only pushing around 4ft of short-period swell. It’s a tease, really. The break is still calling it "poor surf conditions" even then. It’s a classic case of a bit more energy but no real quality.
There is one tiny light at the end of the tunnel, but it’s a long way off. On Wednesday morning, September 2nd, we finally see a glimpse of something. The wind goes glassy, which is huge. It’s a small 2ft of SSE swell at 10 seconds, but the energy is moderate (92) and the conditions are actually clean. For the first time in the whole forecast, it says "surfable waves," but it’s still very ordinary. That is the closest thing to a highlight we have, and it’s a minor one at best. It’s promising, but with it being over a week out, don’t book the day off work just yet.
The rest of that second week is back to the same story: poor conditions, onshore or strong cross-off winds, and tiny swell. Nothing is consistent, and this kind of blank run is a real possibility for this stretch. It’s a waiting game, plain and simple.

Information about the Turtle Cove Surf forecast
The above surf forecast table for Turtle Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Turtle Cove can be found by selecting the local surf guide option on the grey menu. Our Turtle Cove 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 (Turtle Cove) 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 Turtle Cove 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.
