The Lowdown
G’day, Rusty here, and I’ve got the lowdown on the surf ahead for Turtle Cove. It’s a reef and point setup, so it handles swell direction well, and it’s fairly consistent, which is a bit of a silver lining. But I gotta be straight with you—this 16-day window is a tough one to love. The first few days are a write-off, and there’s a real gap in anything worthwhile until we hit some promising windows later on. The water’s sitting at 68°, which is a bit colder than normal for this time of year, so you’ll want a decent spring suit.
Right now, we’re looking at Sunday, August 2nd, and it’s a no-go. Tiny swell around 3 ft from the south with a short, choppy period of 7 seconds, combined energy is weak at 88, and a cross-shore breeze is messing it up. Monday, August 3rd, sees a jump in size—8 ft to 10 ft from the south—but the wind is howling at 28 mph in the morning, and the whole day is either poor or marginal. That energy jumps to 830 and 1187, which is strong, but it’s too big for beginners and the conditions are rough. Tuesday, August 4th, is the first real standout. Early morning brings a clean 5 ft swell from the south at 8 seconds, combined energy of 257, and light offshore winds from the NNW. It’s a crisp, clean start with good surf conditions—definitely the best of the first week. The crowd factor here is “sometimes,” so you might have company, but it’s worth it.
After that, things drop off again. Wednesday through Saturday (August 5th to 9th) are all poor, with messy cross-shore winds, bumpy surf, and weak to moderate energy. The swell hangs around 3 ft to 6 ft, but it’s short-period, sloppy, and the wind never really cooperates. Sunday, August 10th, has a morning with 5 ft from the SSW at 6 seconds, but it’s ordinary—just a marginal whisper at best. The next standout? Friday, August 14th, morning. It’s a small 2 ft from the south, period of 7 seconds, but with light offshore winds from the WNW, the conditions are clean. Combined energy is only 73, so the waves are weak, but it’s surfable after a long dry spell. That’s your best bet in the second week—a tiny, clean session for the patient.
Overall, the pick of the whole period is Tuesday, August 4th, morning. The swell is 5 ft from the south, the wind is light and offshore from the NNW, the energy is solid at 257, and it’s the only true clean session with proper rideable waves. The point break setup should handle the south swell nicely. For the rest, it’s a waiting game, and the forecast confidence drops as we get further out, so keep an eye on it. Rusty out.

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.
