The Lowdown
Alright, let’s look at what’s on offer. Turtle Cove is the only break in the mix. It’s a reef and point, and it’s fairly consistent, so it’s not a bad spot to keep an eye on. The water’s at 70°, which is dead on average for the season, so no drama there.
The first real chance to get wet is Tuesday afternoon, August 25th. Swell is a knee-high 1ft from the SE with a cross-off wind at 16 mph. The combined energy is only 28, so it’s weak and marginal. You’ll be scratching for anything.
The standout is Wednesday morning, August 26th. We’ve got a 2ft swell from the ESE, and the wind is offshore at 9 mph. It’s clean, and the combined energy is 62. For a point break, that offshore wind and a little bit of SE groundswell will give you the best shape of the whole run. This morning is the one to aim for.
The rest of the first week is a wash. Swell stays in the 1ft to 2ft range through the end of August. Winds are often cross-off or cross, with plenty of afternoon breezes hitting 16 to 19 mph. Thursday afternoon, August 27th, has a 19 mph crosswind that will chop it right up. Friday afternoon the 28th sees a 3ft swell with a light offshore, and the energy hits 134 (moderate), but it’s a short 8-second period that will close out a bit on the reef.
Into early September, we get a couple of long-period swells—14 seconds on September 1st and 12 seconds on the 2nd—but the height is a pathetic 1ft to 2ft, and the wind is messy, with a cross-onshore chop on the 2nd. That long period would be beautiful on a point, but with that little size, you’ll be sitting waiting for the rare set.
Later on, Monday morning, September 7th, turns glassy with a light offshore breeze at 3 mph and a 2ft SE swell. It’s clean and calm, but still tiny. The combined energy is 39.
Honestly, the whole 16 days looks small and mostly ordinary. The clear standout is that Wednesday morning, August 26th—2ft, offshore, clean. That’s your window. For everything else, keep the longboard waxed and your expectations low.

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.
