The Lowdown
Alright, Rusty again, but this time in feet and degrees Fahrenheit for you.
Turtle Cove is a reef-and-point break, exposed to the southeast, and generally consistent enough to hold some swell. Right now through the first part of September it’s pretty dead – tiny, weak swells and no real surf to speak of. The first decent opportunity doesn’t roll in until Saturday, September 12, so that’s about 10 days of near‑flatness. Water temp is 70°F, which is right around normal for the season – no anomaly worth noting.
The standout is Saturday morning, September 12. You’ve got a clean 5 ft east swell, period only 6 seconds, but a light offshore wind from the WNW at 9 mph. Combined energy is 208 – moderate oomph for a point. Swell direction is east, not ideal SE, but that offshore breeze will keep the waves clean. Expect some company – this spot can be popular. The short period makes the waves a bit steeper and faster, but on a reef it’ll still give you some fun corners.
Sunday morning the 13th is also good. Smaller at 5 ft from the ESE (closer to optimum), period still short at 7 seconds, energy a solid 318. Offshore wind from the west at 6 mph – glassy. Crowds again likely, but these two sessions are the only real chances. After Sunday, it fades fast. So if you can get out on the 12th or 13th, that’s your shot.
Stay stoked. – 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.
