The Lowdown
Alright, crew, Rusty here again, breakin' down the next two weeks at Turtle Cove in feet and Fahrenheit. Gotta be honest, it's a rough patch. There's a big ol' gap of flatness before we get a single decent wave.
We're lookin' at a solid week of nada starting Tuesday the 1st. Tiny swell, shifty wind, and no energy in the water. A few days like Thursday the 3rd and Friday the 4th have clean conditions, but the swell's barely a foot and a half – short-period, gutless stuff. Don't bother.
The one and only highlight is the morning of Friday the 11th of September. A 5ft SSW swell rolls in, and the wind goes completely dead – dead calm, glassy. The water's at 70°, right where it should be for this time of year. That's your window. The combined energy is a solid moderate 227, so there's some push behind it. For a spot that's been flat as a pancake, that morning is the real deal.
After that, it's back to the small stuff. Friday afternoon fades, and the weekend gets blown out with stronger cross-off winds. Saturday the 12th has a 3ft swell, but the wind's too strong for it to be any good. After that, it's all downhill into tiny, weak surf. So, one morning to get wet, and the rest is a wash. Don't expect much else.
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.
