The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Turtle Cove.
Straight up, the next few weeks are gonna be a real test of patience. We’ve got a long, dry spell of nothing doing from the start until Monday the 24th of August. The first few days are a write-off – tiny, messy, and cross-onshore. Not worth paddling for.
Monday the 24th is where it finally gets interesting. We’ve got a pulse of swell coming in, with surfable waves but very ordinary conditions. The morning is your best bet with a gentle offshore wind from the West, keeping things clean. Swell is coming from the South at 4ft, with a period of 7 seconds. The combined energy is moderate at 134, so it’ll have a bit of push. It’s a beach and reef setup, so that short period will keep it a bit lumpy, but it’s the only real window in the first week.
After that, it’s back to the doldrums. Tuesday the 25th through to the end of the month will be frustratingly small, with most days showing poor surf conditions. The odd morning might have a clean surface from offshore winds, but there’s just no wave height to work with. The water temp is about average for the time of year, nothing unusual.
The highlight of the whole forecast has to be Monday the 31st of August. It’s a long way out, so keep the salt in your veins, but the models are showing a very long period groundswell from the SSE at 18 seconds. The swell height is only 0.7ft to 1.0ft, but that kind of period can wrap into a reef and point like Turtle Cove and produce clean, lined-up waves. The afternoon has a cross-offshore wind from the SSW, and the combined energy is moderate at 92. If this one lives up to the promise, it could be a gem. But with that tiny swell height, it’s a gamble.
The first few days of September are more of the same – clean conditions but tiny. The morning of the 2nd of September has a light offshore and a combined energy of 93, but again, the swell is only 1ft. The 4th of September has a slight bump from the SSW with a gentle offshore wind, but it’s still a marginal day.
Overall, the standout is Monday the 24th of August for the biggest swell, and Monday the 31st of August for the potential quality, but don’t hold your breath on that one. It’s going to be a lean couple of weeks.
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.
