The Lowdown
Alright folks, Rusty here. Let's get straight into it. We've got a 16-day window for Turtle Cove, and I gotta be honest with you, it's looking like a tough stretch for the most part. This is a reef and point setup, intermediate territory, and it needs a decent SE swell to really get going. The problem is, for the first week and a half, we're just not seeing the energy we need. The water temp is sitting at about 70°, which is pretty much what you'd expect for this time of year, so nothing to worry about there.
The first hint of anything resembling a wave comes in on Thursday the 10th. There's a pulse of short-period SW swell, pushing 7ft, but it's a messy, wind-affected beast. The combined energy is strong, reading 501, but the period is a rubbish 7 seconds and the wind is a strong cross-off. That's a lot of power with no shape, and honestly, it's more of a kite-surfing setup than a paddler's wave. That's a pass from me.
After that, the swell drops right back down. We're looking at tiny, weak waves, nothing over 3ft, for the rest of the week. There's a brief moment on Friday the 11th afternoon where the wind goes offshore from the W at 12 mph, but the swell is only 2ft with a 6-second period. It's surfable, but it's ordinary. The energy is weak (50). It's a one-star day at best.
The following week is more of the same. Small, weak swells and inconsistent winds. The 16th of September onwards, we get a few more windows of light offshore winds, but the swell heights are pathetic, barely 2ft. The energy is low, often in the teens or twenties. There's just nothing to get excited about.
So, the bottom line: there are no standouts in this 16-day window. The surf is tiny, and when it does get a bit of size, the wind and period are terrible. You're better off waiting for a better forecast. This is one of those blank runs we sometimes see.

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.
