The Lowdown
Alright, Rusty here again, but in feet and miles per hour for those who think that way.
Turtle Cove is a reef and point break, open to the swell and happy with a SE direction. That’s what’s on the menu for most of this run.
We’ve got a slow start. Nothing worth getting wet for until Wednesday the 26th of August. Early days are tiny – 0.7ft to 1ft, messy wind, no energy. Leave the board at home.
Wednesday morning the 26th brings 2ft from the ESE with a light offshore from the W. Energy is weak at 74, period short at 8 seconds. It’s clean, but barely surfable. Water temp is about normal for the season – nothing unusual.
Thursday the 27th is similar – 2ft, light cross‑off, low energy (57). It’s there, but only just.
Friday the 28th jumps to 4ft from the S, but the wind is cross‑onshore and choppy. Energy hits 148, but it’s not pretty.
Saturday the 29th morning is cleaner – 3ft from the S, light cross‑off, energy 118. Still nothing special.
The best window is Friday the 4th of September. That morning gives us 4ft from the E with a light offshore from the NW, energy 126, clean. The afternoon builds to 4ft from the ESE, energy jumps to 217, period 8 seconds, but wind is light and cross‑off. That’s the one to circle.
After that, it goes downhill. Sunday the 6th has 4ft from the SSE but strong cross‑onshore wind and energy 440 – that’s big and messy, more for kite surfers. Monday the 7th is similar – 4ft, onshore, energy 326.
So, a lot of flat or poor days, with one decent window on the 4th of September. Turtle Cove can be a waiting game – this time, it’s a short 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.
