The Lowdown
Alright, Rusty here. Let’s look at what’s on the cards for Turtle Cove over the next couple of weeks. Honestly, it’s a tough stretch for the most part. We’ve got a long gap of flat, poor-quality surf before anything worth paddling out for shows up.
Right now, we’re looking at nearly a week of nothing. From Saturday the 29th of August right through to Wednesday the 2nd of September, it’s all small, weak waves and poor surf conditions. The water temp is bang on average for this time of year at 70°, so at least a wetsuit won’t be a shock to the system, but the waves are just a non-event. Swell energy is tiny, barely hitting 64 (weak energy) on the best of these days, and the wind is messy.
We finally get a little pulse on the morning of Thursday the 3rd of September. It’s a 3ft swell from the ESE with a short 8-second period, and the combined energy is still only moderate at 143. The wind is a clean cross-off from the SSW, so conditions will be tidy, but the waves themselves are only just surfable – nothing to get excited about. By afternoon it drops off again.
Then another flat spell rolls in until we get a bit of a bump around the 8th of September. On the morning of Tuesday the 8th we see 5ft from the east, but it’s a short-period 6-second wind swell and the energy sits at a moderate 238. The wind is cross-off, so it’ll be clean, but the quality is still pretty marginal. Wednesday the 9th of September morning is the standout of the whole outlook. We get a solid 2ft groundswell from the SSE with a long 11-second period, and a combined swell energy of 212 (moderate). The wind is offshore from the WSW, which will groom the face beautifully. That said, for a reef and point break like Turtle Cove, longer period swells from the southeast aren't bang on its optimum direction, so it won’t fire at its absolute best, but it’s the cleanest, most promising window in the whole 16 days. After that, it all fizzles out again.
The rest of the second week is just small, weak, or onshore junk. Nothing to plan a session around.
So bottom line: if you’re itching to get wet, the morning of Wednesday the 9th of September is your only real shout. It’s not epic, but it’s the best we’ve got by a long shot.
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.
