The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Turtle Cove over the next couple of weeks.
Right off the bat, I gotta tell ya, it's a pretty bleak picture for the first week and a half. We're looking at a long stretch of small, weak, and generally unexciting surf. From Friday the 7th right through to the middle of the month, the waves are just not cooperating. There's a lot of "poor surf conditions" and "surfable waves but very ordinary conditions" – which is surf-speak for "probably not worth paddling out." The combined swell energy is weak, mostly in the double digits (57, 80, 103), and the swell periods are short, around 6 to 8 seconds, so the waves are just gonna be soft and crumbly. The best you can hope for is a couple of mornings with clean, offshore winds, but the swell just isn't there to back it up.
The real story here, the one that gets my heart pumping a little, is that Wednesday morning, the 19th of August. That's the standout. The models are pointing to a nice little spike of swell pushing in at 5ft from the ESE. Now, the period is 8 seconds, so it's not a long-period groundswell, but it's a solid pulse of energy with a combined swell energy reading of 258 – that's moderate to strong. But the real kicker is the wind. It's forecast to be glassy. Zero wind. That means absolutely perfect, clean conditions. The water temp is sitting about a degree and a half cooler than average for this time of year, so you'll want a slightly thicker spring suit, but that clean, glassy surf will be worth it. This is the one to circle on your calendar. It's a bit over a week away, so keep an eye on the forecasts, but this is promising. If you're a beginner, 5ft might be a bit on the punchy side, but for an intermediate surfer, it's a great size for Turtle Cove.
After that little burst, things settle back down again. The Saturday and Sunday after the 19th see some onshore winds and the swell gets messy, so don't expect a long run of good waves. This is a spot that's exposed to the SE, and when the swell switches to that direction, it can get a bit walled up and choppy with the wind.
So, to sum it up: the next week and a half is a write-off. Don't bother. Save your energy for that Wednesday, August 19th. Glassy, clean, and a decent swell. That's the only real window of opportunity in the whole 16-day outlook.
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.
