The Lowdown
Alright, this is Rusty, and I’ve got a good look at the only break on the menu for the next couple of weeks: Turtle Cove. It’s a reef and point setup, and according to the data, it’s fairly consistent, but the timing for decent waves is going to test your patience.
Overall, the pattern is pretty grim for the first week and a half. We’re looking at a long stretch of flat or very small, messy conditions. The water temp is sitting right around 70°, which is pretty normal for this time of year, so no surprises there.
The first real opportunity doesn’t show up until Thursday morning, September 22nd. That’s a long wait. For almost two weeks, the surf is mostly tiny, with poor quality and average wind. The best of the best, the true standout, is that Thursday morning session. We’ve got a moderate energy swell (417) pushing in at 7ft from the ESE, which is solid and a good match for the break’s optimum direction. The wind is cross-off from the SSW, and the report says "expect good surf conditions." That’s the one to circle on the calendar.
The afternoon of the 22nd drops off quickly, and then it’s back to small stuff through the end of the forecast.
The standout: Turtle Cove on Thursday, September 22nd, morning. It’s getting a 7ft ESE swell with a clean cross-off breeze. That’s your best shot by a long shot. The period is only 7 seconds though, so it’s a short-period swell, not a long-period groundswell that would really draw lines across the reef, but given the size and the wind, it’ll still be a fun session.
The rest of the time? It’s mostly flat, blown out, or cross-on. Sunday the 13th has a glassy afternoon but only 2ft – not much to write home about. The 20th and 21st have some swell, but the wind is onshore or cross-shore, making it a messy affair. The 6ft to 7ft swells that week are really more for the kite crew than paddlers, to be honest, given the poor conditions.
So, hang tight. The first two weeks are a write-off for anything decent. That Thursday morning on the 22nd is the only real window. Don’t hold your breath for the rest.

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.
