Alright, grab your stick and let’s see what Turtle Cove has cookin’ for the next couple weeks. It’s a reef and point, lookin’ for that SE groundswell.
First things first, the beginning is a tough slog. We’ve got weak, short-period surf out of the SE, barely a foot tall, and the wave energy is in the dumps – just small numbers in the tens. The wind’s all over the place, often onshore or messy, and there’s even a chance of thunderstorms on the afternoon of Saturday the 4th. Don’t bother waxing up for the first week. The water temp is pretty normal for this time of year, nothing wild.
We finally get a little life on the morning of Saturday the 11th. The swell bumps up to about 3ft from the south, with a 8-second period and moderate wave energy of 152. The wind is offshore from the west, light, and that’s clean. Keep in mind, this spot can get a few heads in the water, and it’s not always breaking. But for the first real clean window, it’s our earliest standout.
The next one to circle is the morning of Wednesday the 15th. The swell jumps to nearly 6ft out of the SSW, with a 7-second period and strong wave energy of 310. The wind is cross-off from the southwest, keeping things tidy. That’s a proper push of energy. The water’s still running average for mid-July.
On the morning of Saturday the 18th, the surf is tiny – just about 1ft from the SE – but the wind is dead glassy from the northwest. That’s pure gold for a reef break, even if you’re only catching knee-high rollers. The swell period hits a long 13 seconds in the afternoon, but with next to no height, it’s not going to unload.
Looking way out to the morning of Sunday the 19th, we see another bump: 6ft from the SSW, 7-second period, and 331 of combined energy. The wind is cross-off again. It’s a similar setup to the 15th, but it’s two weeks away, so treat it as a hopeful flicker.
For my money, I’m chasing the morning of Saturday the 11th for the cleanest combo, and the morning of Wednesday the 15th for the biggest, punchiest waves. The rest is mostly flat or junky. That 6ft swell won’t wreck you, it’s solid intermediate fun on a reef or point, not expert-only.
Keep your eyes peeled and your wax on. No buoys to read, just the water call.

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.
