Table - best surf conditions forecast for Turtle Cove over the next 16 days.
Listen, I’m gonna level with you. For the whole 16-day run at Turtle Cove (Turtle-Cove), we are staring down the barrel of a garbage forecast. There’s hardly a wave worth paddling for, and we’re looking at a solid stretch of flatness right at the beginning.
The first sign of life, and I use that term lightly, is on Wednesday, July 15th. The morning pushes up to 4ft from the SW, but the period is a weak 6 seconds, so the energy is only moderate at 157. The wind is offshore from the WSW, so it’ll be clean, but the waves will be gutless. The afternoon is smaller, dropping to 4ft.
After that, it dries up again. Thursday and Friday are tiny, with 2ft waves on Friday. Then on Monday afternoon, July 20th, the swell jumps to 6ft from the SSW, but the wind screws it with a cross-on from the SE, making it bumpy and ugly. The water is a chilly 66°, which is a solid 4° colder than it should be this time of year.
The only other window is Tuesday, July 21st. It has some size – 6ft in the morning and 5ft in the afternoon – with moderate to strong energy (267 and 202). But the period is short at 6-7 seconds, so it’s weak and lumpy. The afternoon has clean cross-off wind, making it look better than it probably is, but the quality is still listed as marginal.
Wednesday the 22nd fades to 4ft with clean wind, and then it’s a slow flatline to the end.
There is no stand-out day here. No groundswell with a long period to chase. Just a series of small, weak, or messy waves. This is a rough spell. The only people having fun will be the ones on a kite with the strong, clean cross-off winds on the 15th and 22nd. For the rest of us, it’s a waiting game.
Keep the wax in the wrapper.

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.
