The Lowdown
Alright, folks, Rusty here. Let's have a look at what's heading our way for the next couple of weeks.
Right off the bat, I gotta be straight with you – it's a tough stretch. The first week and a bit is looking pretty flat and average. We're staring down a long gap with next to nothing rideable. For the first few days, it’s just tiny dribbles, and the wind is all over the shop, so don't bother paddling out until we get deep into the second part of the window.
The real story starts to build late in the second week. Gonna be a waiting game.
The only spot we've got on the radar is Turtle Cove, a reef and point setup. The water temp is sitting right around average for this time of year at 71°F, so nothing wild there, just a standard wetsuit or springsuit job.
We’ve got a long dry spell. Absolutely nothing worth mentioning for the first week. You could check the tide pools, but that’s about it. The mornings of the 17th and 18th show a slight bump, with a 4ft swell on Monday the 17th and 2ft on Tuesday the 18th, but the wind is messy and they still rate as “poor.” Not worth the paddle.
Now, heading into the end of the window, things finally get interesting. On Friday the 21st of August, we see a push of energy. The morning brings a 6ft SSW swell with a period of 7 seconds, and combined energy hitting 284 – that's moderate wave energy. The wind is a cross-off from the NW, which should keep it clean. This is the best we’ve seen by a long shot. It’s still a short-period swell, so it won't have the punch of a groundswell, but 6ft clean and lined up at a reef setup like Turtle Cove is a good look. The afternoon holds at 5ft with a WNW cross-off. This is your standout window.
Then it gets interesting, but for the wrong reasons. By Wednesday the 26th, we’ve got a 6ft ESE swell rolling in. That’s pushing expert-only territory at over 5ft, and the period is only 8 seconds with combined energy of 439 – that's strong. But the wind is a cross-on from the NNE and SE, which will chop it up. For a paddle surfer, that’s a tough look. That setup is looking way more interesting for kite surfing than a standard paddle session.
So, to sum it up: there’s a 10-day gap of rubbish before we get a brief window on Friday the 21st. That morning is your one true standout – hit Turtle Cove for the clean 6ft SW swell. After that, it gets big, messy, and onshore.
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.
