The Lowdown
Right. Rusty here. Let’s be straight with you: this stretch of the next 16 days is a pretty bleak one for a paddle. You’re looking at a whole lot of small, weak swell and ordinary conditions for the most part. There’s a good chunk of nothing in the middle, and the only real glimmer of hope is way out there on the horizon.
The outlook kicks off with nothing worth mentioning. We’ve got a solid run of days from Sunday the 23rd of August right through to Friday the 4th of September where the surf is just not happening for a proper session. You’ll see tiny 0.7ft to 3ft waves, mostly from the SE or S, but the wind is all over the shop – cross-onshore, cross-off, or just messy. There’s a brief tease on Monday morning the 24th with a 3ft S swell and offshore wind, but it’s a 6-second period wind swell, so it’s gutless. Not worth suiting up for.
Things stay flat and weak. Even when there’s a bit of energy, like the 4ft SSE swell that shows up on Saturday the 5th of September, the conditions are still described as “marginal.” That’s the only standout in this entire 16-day window.
Alright, here’s the one to keep an eye on. Saturday the 5th of September at Turtle Cove (reef and point). The swell jumps to 4ft from the SSE, and it’s a groundswell with a 13-second period – that’s decent energy and shape. The combined swell energy hits 578 (moderate wave energy) in the morning and stays at 538 in the afternoon. The morning has a fresh cross-off breeze, but the afternoon shapes up better with a moderate offshore wind from the WNW. That will clean things up nicely. The water temperature is 71°F, about average for this time of year. For an intermediate, that’s a fun, solid day. It’s not giant, but it’s the best on offer. Just a heads up: this is a long-range call, so it’s promising but far from locked in.
After that, it fades again quickly. Sunday the 6th drops to 3ft with cross-onshore wind, and the week after is back to tiny, weak junk.
So, if you’re chasing, pencil in Saturday the 5th of September at Turtle Cove. Everything else is a write-off. The rest of the 16 days is a gap you can spend waxing your board and waiting. Forecasts can change, though. A stretch this empty tends not to stay that way forever.
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.
