The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Turtle Cove (Turtle-Cove) all morning. Let’s be honest with each other — this next couple of weeks is looking pretty grim. The water temperature is sitting about average for this time of year, so no excuses there, but the swell just isn’t showing up with any real energy.
The first recommendation we get is for Monday morning, the 31st of August. That’s a long wait from now with nothing but poor surf — a proper gap of a few days with no real options. Come Monday morning, we’re looking at a tiny 3 ft SSE swell, but with a shockingly short period of 5 seconds, so the combined energy is weak at just 59. The wind is a light WNW cross-off, so it’s clean, but honestly, it’s barely surfable and very ordinary. The afternoon glass-off is even smaller, so not worth paddling out.
Then we hit a real rough patch. From Tuesday the 1st of September through to the end of the week, the wind is howling onshore from the east and northeast, ramping up the swell height but absolutely destroying the quality. The combined energy climbs to a moderate 175 by Wednesday, then on Thursday the 3rd of September, we see a big 10 ft E swell with 1040 energy — strong, powerful stuff. But with the wind squarely onshore, it’s a mess. That’s expert-only territory, and even then, the conditions are ugly. For a break like Turtle Cove, a reef and point setup, that much onshore wind makes it more of a kite-surfing session than a clean paddle surf.
The following days don’t get much better. The swell drops back down, but the wind stays onshore or cross-onshore, keeping the surf lumpy and average. There’s a slight flicker on Tuesday the 8th of September — a light offshore WSW wind with a 4 ft SSE swell, period around 6 seconds, and combined energy of 101. It’s surfable but very ordinary. Clean, but weak.
The last few days into the second week are tiny and weak, with combined energy dropping to 24 by Friday the 11th of September. Offshore or light winds keep it clean, but there’s simply no power.
So, the standout? Honestly, there isn’t a true standout here. If I had to pick one window, it’s the Monday morning of the 31st of August — the only session where the wind is kind and the swell is just about big enough for a log. But that’s a stretch.
Hang in there, folks. Forecasts can change, and this area tends to bounce back.
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.
