The Lowdown
Alright, this is Rusty. Let's get into it.
Alright, look, we're gonna have to be patient for the next 16 days. For the first few, there's just not enough energy to get excited about and the conditions are a bit mixed. But there is one real standout window where the stars align, so let's get to it.
The action starts on Tuesday the 4th of August. It's not a huge day, but conditions are a real treat. The early morning at Turtle Cove is glassy, with a 5ft south swell pushing in. The energy is moderate (285), and with that light 3 mph offshore wind, it will be clean. This is a reef and point setup, and the swell period is a bit short at 8 seconds, so it won't have the grunt of a groundswell, but for a morning session, it's the best on offer. Be aware, Turtle Cove can get crowded sometimes.
The wind swings around to the south, picking up to 9 mph in the afternoon, turning it cross-shore and making things messy. The swell drops off quickly after that, with a few days of poor surf between Wednesday the 5th and Saturday the 8th. The 8th of August has a small 3ft swell, but it's still weak and winds are strong.
The next real chance comes on the morning of Monday the 10th of August. There's a 4ft swell from the SSW, but the real winner here is the offshore wind. It's a gentle 9 mph from the west, cleaning up the waves. The energy is moderate (99) but the swell period is short at 6 seconds, so it's not going to be a classic. Still, a clean, offshore morning is a solid option.
The second week is a bit of a write-off. There's a flat spell from the 11th through the 19th, with very small, weak swell and poor conditions. The only glimmer is on the morning of Friday the 14th of August. The wind is completely glassy, which is a huge positive, but the swell is only 2ft with very weak energy (66). It's a long shot for a log, but you'd be working for it.
Overall, the standout is the Tuesday morning of the 4th of August. That glassy, offshore window with a 5ft south swell is the cleanest we'll see. The Monday morning of the 10th is a good second option, with the offshore wind making it rideable. After that, it's a long wait for the ocean to wake up.
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.
