The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cookin’ for Turtle Cove over the next couple of weeks.
Honestly, right out of the gate, it’s a bit of a slow burn. The first few days are looking pretty flat and grotty. We’ve got a long dry spell from Saturday the 29th of August right through to Wednesday the 2nd of September, with nothing but tiny, weak waves and poor conditions. That’s a solid six days of not much to write home about. The swell energy is barely registering, with readings like 68 and 31, and the period is a short, weak 8 seconds. Just not worth paddling out for.
The first real glimmer of hope comes on Thursday the 3rd of September, in the afternoon. An offshore wind from the west, around 15 mph, is gonna clean things right up, and we’ll see a solid 4 ft swell from the SSE. The wave energy is really kicking in at 234, so there’s some proper push behind it. The reef and point setup at Turtle Cove should handle that direction well. It’s the first decent window of the whole forecast.
Then things get a bit messy again. Friday the 4th and Saturday the 5th flatten out with tiny 2 ft and 1 ft surf, and even though the wind is offshore, there’s just not enough juice.
Now, the real standout for the whole outlook is Monday the 7th of September. The morning starts with a clean 6 ft swell from the south, energy at 232, and a light cross-off breeze from the northwest. The afternoon is the absolute pick of the bunch: a 7 ft swell from the SSE, with a gentle 9 mph offshore wind from the west, cleaning it up perfectly. The energy jumps to 428—that’s moderate to strong—and it’s gonna be clean and lined up. This is the session to circle on the calendar. It’s big enough for the intermediates to have a ball, but anyone new to the game might find that 7 ft a bit too much.
After that, the middle of the second week gets a bit choppy and inconsistent again. A couple of windows on the 11th and 12th of September show some promise, but the wind is either too strong or onshore, making it messy. The 13th of September is a write-off with onshore winds and tiny surf.
So, bottom line: it’s a waiting game. The first week is a bust, but that afternoon window on the 3rd of September and the whole of Monday the 7th of September are the two highlights. Keep your eyes on the 7th for the best waves.
Rusty.

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.
