The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s headed our way for Turtle Cove over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a pretty quiet stretch. There’s a long gap with nothing worth paddling out for. The first real sniff of something happens on Friday morning, the 28th of August, but it’s not gonna have you calling in sick. We’ve got small 3 ft swell out of the southeast, with 8-second period and combined energy reading just 118 (weak). The cross-off wind from the southwest at 9 mph keeps the surface clean, but the waves are small and the conditions are very ordinary. It’s surfable, but barely. Afternoon drops off even more.
Then we hit a big dry spell. From Friday afternoon all the way through to Thursday the 3rd of September, it’s a total write-off. Day after day of tiny waves or onshore junk. Wind keeps swinging around, and even when it’s offshore, the swell is basically gone. There’s a day with some heavy rain and moderate offshore wind on the 1st of September, but the swell is only 1 ft – a total non-starter.
The next little window shows up on Saturday the 5th of September. Now this is where we finally see some life. The morning is glassy – calm wind, just a slight air – and we get a 2 ft easterly swell that’s got some proper length to it at 12 seconds. The combined energy bumps up to 130 (moderate). It’s still small, but the long period should produce a cleaner, more lined-up wave at this point and reef setup. The optimum direction is southeast and this is coming from the east, so not quite perfect, but it’s the best we’ll see. Afternoon keeps it going with 2 ft and 156 combined energy, and the wind is still clean. The afternoon of the 6th of September also goes glassy again with similar conditions. If you’re gonna go, that Saturday morning or Sunday afternoon window is the pick of the bunch. Just know the swell is only around 2-2 ft, so you’ll need a log or a fish.
After that, the models lose interest again. The second week drifts back into tiny surf and inconsistent bits of energy, with most days showing 1 ft to 2 ft and weak combined energy below 100. Even when the swell period stretches out to 11 or 12 seconds, there’s just not enough height. Thursday the 10th of September shows a pulse of 4 ft from the south-southwest, but the period is only 7 seconds, and it’s accompanied by a messy cross-on wind – not a good combo.
Overall, if you're desperate for a paddle, aim for that Saturday the 5th or Sunday the 6th of September morning or glassy afternoon. Otherwise, this forecast is mostly a waiting game.
Stay patient.

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.
Turtle Cove is 34 km (21 miles) from Westerly. If you plan a vacation in Long Island New York, look for hotels and other accommodation in Westerly. Westerly has rooms for a wide range of budgets as well as car hire and transport links.
