The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Turtle Cove over the next couple of weeks.
Alright, straight up, I gotta be honest with you – this is a pretty bleak stretch of forecast for Turtle Cove. We're looking at a solid run of poor surf conditions that stretches all the way from the start of the period through to the end of the second week. There's no real standout session coming, and the wave energy is consistently weak. The water is sitting at 69°F which is a bit colder than normal for this time of year, so don't forget that spring suit.
We kick off on Thursday the 30th of July with a 4ft swell from the south, but it's got a short 8-second period and the wind is a cross-shore from the NNE at 9 mph. The combined energy is only 182, so it's weak, and the conditions are poor. Friday morning, the 31st, is the best we'll see for a while – a 3ft south swell with a 9-second period, and the wind goes glassy from the SW at 3 mph. That's clean, but it's still just "surfable waves but very ordinary conditions." The energy is still low at 165. That afternoon, the wind picks up to 12 mph from the SSW, making it a cross-offshore, but the swell drops to 3ft.
From there, it's a long grind. Saturday and Sunday the 1st and 2nd of August are all cross-shore winds and lumpy, weak swells. The energy numbers drop – 162, 177, then down to 91 by Sunday. The period stays short, around 7 to 8 seconds. Through the following week, Monday the 3rd of August has a 4ft swell but it's from the south with a 7-second period, wind is 19 mph cross-shore, and the energy is 136. It's just a messy, choppy setup. The wind is onshore or cross-shore for almost every day, with speeds often around 12 to 15 mph, making it tough for a clean wave.
The second week is completely flat. From Tuesday the 5th of August onward, the swell heights drop below 3ft, mostly hovering around 1.0ft to 3ft, with periods as short as 4 to 7 seconds. The energy numbers are mostly in the teens or low twenties. Even when the wind goes glassy on the morning of Monday the 10th of August, with a 3ft swell from the SSW, the energy is just 72 and the wave comment is "surfable waves but very ordinary conditions." Thursday the 13th of August has a glassy morning too, but the swell is a tiny 1.0ft. The end of the period on the 14th has a cross-onshore wind from the ENE at 16 mph and a 3ft swell with a 4-second period – that's just choppy, poor surf.
To be honest, this is a rough run. There's no real standout here. The only window that looks even remotely worth a paddle is Friday morning, the 31st of July, when you get that glassy wind and a 3ft swell. Even then, it's ordinary. The rest of the 16 days is a write-off. If you're desperate, go for that Friday morning, but don't expect much. The conditions are just too weak and windy for anything decent.
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.
