The Lowdown

Alright, I’m looking at the charts for Turtle Cove and honestly, it’s a bit of a slow burn to start. The first real surf we can talk about doesn’t kick in until Tuesday the 4th of August, and even then it’s pretty average.

Right off the bat, Tuesday afternoon sees a weak 3ft swell from the south with a short, crumbly 8-second period. The combined swell energy is only moderate at 153, but the wind is a cross-shore breeze at 9 mph, so it’s not clean. The water’s sitting at 69°, which is a bit colder than normal for this time of year.

Wednesday the 5th stays small – a 2ft south swell with a period of just 7 seconds. Morning looks okay with a light cross-offshore wind making it clean, but the energy is weak (86). It’s surfable, but nothing to get excited about.

Thursday and Friday are more of the same: small, short-period swell, and the wind picks up in the afternoons, ruining any chance of quality. The combined energy is weak, under 100.

Saturday the 8th actually sees a bump in energy to 115 by the afternoon with a 4ft swell, but that fresh 19 mph cross-offshore wind is just too strong. It’s going to be choppy and messy.

Now, Sunday the 9th morning is a slight bright spot. We’ve got a clean 3ft swell with a gentle offshore breeze – that’s a good combo for a reef and point like Turtle Cove. The energy is still weak at 83, but the conditions are there for a few fun, clean rides.

The real standout is shaping up for Monday the 10th of August. That morning, the swell jumps to 5ft from the SSW, period bumps to 7 seconds, and the combined energy is a solid moderate 359. More importantly, we get a gentle offshore wind and clean conditions. That’s the pick of the early run – proper waves, good shape, and a bit of power behind them. If you can only go once that week, that Monday morning session is your best bet.

After that, it gets quiet again. Tuesday the 11th drops back down, and Wednesday the 12th is basically flat with tiny 0.3ft swell.

But hold on, because the real highlight of the whole forecast is Saturday the 15th of August. That morning we’ve got a solid 6ft SSW groundswell, with an 8-second period, and the combined energy is a strong 463. The wind is glassy – dead calm. That is going to be a dream session at this reef and point. Afternoon stays good too, with 6ft and clean conditions. That is the day to circle on your calendar. It’s over a week away, so things could change, but if it holds, it’ll be the best surf of the whole window.

Sunday the 16th still has some leftover 4ft swell, but the wind shifts and the quality drops off. After that, it’s pretty much done – small, weak swells and onshore winds for the rest of the outlook.

So, to wrap it up: the first week is small and mostly average, with Monday the 10th morning being the one to sneak out for. But the true standout is Saturday the 15th – glassy, solid 6ft groundswell, perfect for Turtle Cove. Don’t sleep on it.

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.
