The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window for Turtle Cove, and I’ll be honest with you, this is a lean stretch. The surf is small and the conditions are mostly ordinary, so don’t get your hopes up for anything epic. The water’s sitting at about 70°, which is a little colder than what we normally expect this time of year, so you might want a steamer if you’re heading out.
The first few days are a real struggle. Friday the 7th of August has a tiny 1 foot SE swell, but with a 16 mph cross-off breeze, it’s messy and not worth paddling out for. Saturday the 8th shows a bit more push in the morning – 3 feet of SSW swell – and the wind swings offshore from the WSW at 9 mph, so it’s clean. But the wave energy is still weak (99) and the period is a short 6 seconds, so it’s really just ankle-biters. Sunday the 9th morning is similar, with 4 feet of SSW swell and a clean offshore wind, but again, very ordinary.
We get a brief moment of glass on Monday the 10th morning with a 2 foot swell and zero wind, but the energy is gone (40) and the waves are pathetic. There’s a long gap of poor, weak surf through the middle of the week. The 15th of August Saturday morning brings a 3 foot S swell with moderate wave energy (101) and cross-off winds, but it’s still nothing to write home about.
Now, for the one real standout. It’s not a huge wave, but the conditions finally align. Monday the 17th of August morning: a tiny 0.7 foot SSE swell, but check the period – 14 seconds, that’s a very long groundswell. The wind is offshore from the W at 9 mph, making it clean and glassy. The wave energy is low (53), but for a reef and point break like Turtle Cove, that long-period swell will wrap in nicely and offer some proper, lined-up waves. It’s a short window, but if you’re keen, this is the best on offer. The forecast is a week and a half away, so keep an eye on it, but it’s promising.
The rest of the month is a write-off. Small, onshore, cross-off, and generally poor. The 22nd of August has a 3 foot S swell with moderate energy (105), but the wind is light cross, and it’s just not enough to get excited about.
So, to sum it up: the best bet is the morning of the 17th of August. It’s a delicate, long-period groundswell with clean offshore wind at Turtle Cove. Don’t expect a big day, but for a quiet, clean session, that’s your window.
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.
