The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Turtle Cove over the next couple of weeks. I gotta be straight with you – this is a pretty bleak stretch for paddle surfing. The quiet spell is gonna feel long, but we do have one little window that’s got my attention.
Right now, we’re lookin’ at a whole lot of nothin’. From Friday the 31st of July all the way through to Sunday the 9th of August, the surf is either tiny, blown out, or just plain messy. There’s a couple of days where the swell is around 3 ft, but the wind is just cross-off or cross, and the scores are all zero. The water’s sittin’ at 69°, which is a bit colder than normal for this time of year—so throw a hoodie on if you’re stubborn enough to paddle out. The combined energy is weak, mostly in the 50–160 range, with a few big spikes but those come with howling onshore winds. That Monday afternoon (3rd of August) sees a 7 ft S swell with 25 mph winds—that’s more of a kite-surfing setup than a wave you’d wanna paddle into.
Then there’s a real gap. From Tuesday the 4th through to Sunday the 9th, the swell drops and the wind stays messy. A few marginal sessions pop up on the 4th with 6 ft and 5 ft, but the wind is light onshore and the energy is moderate (335 and 215). It’s just not worth the hassle.
But hold on—Monday the 10th of August, that’s the one. Tuesday morning is the standout. The swell is a solid 7 ft from the south, period 9 seconds, and the combined energy pumps up to 689—that’s strong wave energy. The wind? Glassy. Dead flat, offshore from the southeast at 3 mph. Turtle Cove is a reef and point setup, so this longer-period swell (9 seconds) will wrap in nicely, givin’ you clean, punchy walls. The water temp is guessin’ average. This is a morning for the intermediate crew—7 ft is a bit much for beginners, but for the experienced, it’s gonna be a dream. Just keep in mind, this is a week and a half out, so it’s promising but not locked in. Crowds are sometimes a thing here, so get there early.
After that, it fades hard again. The rest of the 11th through to the 15th is small, mostly 2 ft to 4 ft, and the wind is either cross-on or onshore. The energy drops to weak–moderate. Tuesday afternoon the 11th has a 4 ft south swell with glassy conditions, but it’s just ordinary. Not worth a special trip.
So, the only real stand-out window is Monday morning (10th of August) at Turtle Cove. If you can score that, you’ll be smilin’. Otherwise, save your wax and wait for the next pattern.
Stay safe, 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.
