The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Turtle Cove.
It’s a pretty quiet start. We’ve got a solid gap of nothing much for the first little while. The first real stretch of anything worth paddling out for doesn’t show up until the 22nd of August, so that’s a good stretch of quiet days.
For the first week, the odd bit of small swell shows but the wind is generally messy or cross-off, and the energy is just too weak. The morning of the 9th sees a 3ft swell from the SSW with a short 6-second period, and the wind is clean offshore from the W at 18 mph, but the overall energy is only 86 – pretty weak. It’s surfable but very ordinary. Not one to get excited about.
The next week looks similar, with most days serving up knee-high slop and poor conditions. The 21st of August does see a bit of a pulse in the energy, with moderate cross-onshore wind though, and the ride is not great. The 22nd of August is where it gets interesting. That morning, the wind is light and offshore from the SSW, the swell is a solid 4ft from the SSE with a period of 11 seconds, and the combined energy hits 383 – that’s moderate to strong energy. The forecast says expect good surf conditions. This is the standout. It’s the only morning in the whole 16-day window that looks genuinely good.
Turtle Cove is a reef and point setup, so that longer 11-second period is going to wrap in nicely. The water temp is sitting at 72°, which is basically normal for this time of year. The wind is glassy and light, so the surface will be clean. This is the one to aim for. The crowds can show up sometimes, but on a morning that good, it’s worth the company.
The 22nd afternoon drops off a little, and the 23rd has strong winds that’ll mess it up. So don’t sleep on that Saturday morning.
Keep it salty,
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.
