The Lowdown
Alright, Rusty here, and I’ve had a good look at the charts for Turtle Cove. Straight up, the next couple of weeks are looking pretty grim for paddling. The period kicks off on Monday the 31st of August, and we’ve got a long, flat, and messy stretch ahead. The swell is tiny, under 2 ft for days, with weak energy (around 27) and short period windswell. The wind is mostly cross-on or onshore, and the water temp is sitting at 70°, which is normal for the time of year.
There’s a real dry spell here. From Monday afternoon the 31st, right through until the morning of Thursday the 3rd of September, you’re looking at pretty much nothing worth suiting up for. The small swell gets a little bump on the 2nd, with combined energy hitting 251, but it’s wind-affected onshore slop, so don’t get excited.
Thursday the 3rd of September morning shows a tiny flicker of life – a clean 3 ft swell from the SE at 6 seconds, with light cross-offshore winds. The energy is moderate (114), but it’s still small and ordinary. It’s surfable, but just barely.
The next real hope doesn’t come until Sunday the 13th of September. That morning, the swell jumps up to 7 ft from the SSW, with a short period of 7 seconds and strong energy (485). The wind is light cross-shore, so it’s a bit messy. But the standout is Sunday afternoon – 8 ft of SSW swell, energy roaring at 571, and clean cross-offshore winds. That’s the pick of the whole forecast. It’s a solid, powerful swell, but it’s short period, which means it’ll be a bit lumpy and won’t have that groundswell glide. Still, for Turtle Cove (a reef and point setup), it’ll be a lot of fun for the intermediates. The size is pushing into expert territory, so beginners should sit this one out.
The clean conditions hold into Monday the 14th of September morning, with a 5 ft S swell and light cross-offshore winds – good, clean, and manageable. The energy drops but is still moderate (253).
After that, it’s back to dribble and onshore wind from the 15th, so that Sunday and Monday window is really your only shot. The wait is long, but when it comes, it’ll be worth it.
Keep your eyes on that Sunday the 13th afternoon – that’s the one.
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.
