The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for the next couple of weeks at Turtle Cove.
It's a tough stretch, I'm not gonna lie. We're lookin' at a long, slow grind for most of the 16-day window. There are a few sprinkles of hope right at the very end, but you're gonna need some patience.
The immediate outlook is a real bummer. From Thursday, the 10th of September, right through to the 21st of September, there's just nothing to get excited about. We're talkin' near two weeks of flat, weak dribble. The swell direction is all over the shop, and when there is a tiny pulse of energy, the winds are messy.
There is a tiny flicker of hope on Sunday morning the 13th. The combined swell energy is still low at 95, with a 3ft swell from the SSE, but the wind is a light offshore. It’s surfable, but very ordinary. It’s not a recommendation, just a hint that the ocean is still alive.
Monday the 14th afternoon offers a brief moment of calm – glassy conditions with a 2ft SE swell (57 energy). It's barely a ripple, but if you're desperate for a paddle, it'll be pretty as a picture. Don't expect any power, though.
The big change comes on Monday the 21st of September. The combined swell energy jumps up to 245, with a 6ft swell from the ENE (period 6 seconds). The following day sees a similar 5ft swell from the ENE (energy 234). This is the biggest and most powerful swell of the whole period. It’s not tiny. However, and it's a big however, for these days the wind is crankin' hard onshore from the east. Fresh to strong breeze cross-on conditions mean the wave quality will be blown out and lumpy. The setup looks more interesting for kite surfing than paddle surfing, to be honest. If you're an expert paddler and you just want some size, you might find a sheltered corner, but for most, it's gonna be a mess.
The cleanest opportunity in this window is hidden at the very end. On Thursday the 24th of September, we get a 3ft ESE swell with 201 energy and a clean offshore wind from the WSW. That is a proper window. The water temp anomaly is about average for the time of year, so grab the spring suit. This is the one to circle on the calendar. Friday the 25th morning is a smaller follow-up with an offshore wind too (2ft, 108 energy), but Thursday is the true standout. Keep your expectations tempered – it's not a massive swell, but with that wind, it'll be clean and fun on the point and reef setup at Turtle Cove.
So to sum it up: a long, flat spell, then a windy, chunky period, and finally a clean but modest swell at the very end. The promise is there for the 24th.
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.
