The Lowdown
Alright, Rusty here, let's break down what's happening at Turtle Cove for the next couple of weeks.
Honestly, the first week is a bit of a bust. Starting Sunday, August 16th, it's tiny—about 1ft—and glassy, but the energy is only 19 (weak). It's just not doing anything. Monday and Tuesday see a little more push, but the wind is all over the place—cross-on or cross-off with a fresh breeze. The energy bumps to 145 (moderate) on Tuesday morning, but the swell is only 4ft from the SSE with a short 7-second period. Not worth rushing out.
Wednesday the 19th is the first time we get a "surfable" call, but it's still ordinary. Early morning is clean with a light offshore from the SW and 2ft from the SE (53 energy). You could get wet, but it's not exciting.
After that, it's poor surf through the rest of the week and into the weekend. Friday the 21st has 4ft from the NNE (111 energy), but the period is a terrible 5 seconds and the wind is cross-on. No thanks.
Finally, Monday, August 24th gives us a little hope. Early morning is glassy, clean, with 2ft from the S on a 6-second period. Energy is only 60 (weak), but it's surfable. If you're keen, that's your chance.
Then it goes quiet again until Thursday, August 27th. The morning shows some real promise: 2ft from the SE with a much better 12-second period, energy of 182 (moderate), and a clean cross-off breeze from the NW. That's the standout of the whole forecast—small but clean, with some long-period groundswell wrapping into the point. The afternoon gets choppy, but the morning is the one.
The last few days of August see the swell building—5ft on Sunday the 30th, 5ft on the afternoon, even 6ft by Monday the 31st. But the wind stays cross-on or onshore, and the periods are short. Energy is high—377 (moderate) on the 31st—but with that wind and short period, it's going to be a choppy mess. That setup looks more interesting for kite surfing than paddle surfing.
So, bottom line? The best bet in the whole 16-day window is the morning of Thursday, August 27th at Turtle Cove. Small, clean, and that long-period SE groundswell will work well at this reef and point break. Crowds are "sometimes" here, so you might have it quiet. Water temp is about average for this time of year.
Other than that, it's a long stretch of small, windy, or short-period junk. Keep an eye on it—forecasts can change, and it rarely stays poor for long around here.
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.
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.
