Alright, this is Rusty, and I’m looking at the charts for Turtle Cove. Let’s be straight with you – it’s a tough stretch ahead. This is a reef and point break that works best with a solid SE swell, and we just aren’t seeing that lineup for a while.
We’re into a dry spell right off the bat. The first week is pretty much a write-off. From Saturday the 11th right through to the 15th of July, the waves are tiny, the energy is weak (combined energy values are mostly in the low double digits, like 64 or 37), and the wind is messy. You’ll see a bit of height on the Wednesday morning the 15th, with a 4ft swell from the SW, but the period is a short 6 seconds, so it’s going to be weak and lumpy – not worth paddling out for.
The real story starts to change on Monday the 20th of July. The swell picks up, but it’s not pretty. The wind is cross-onshore or onshore, and the waves are a messy 6ft to 6ft from the SSW and S. The energy jumps up to 464 (strong), but it’s a choppy, blown-out mess. This is a beach-and-reef setup, and with that strong wind, it’s honestly looking more interesting for kite surfing than a paddle session.
Now, if you’re patient and you’ve got the skills, there is a standout window early on Tuesday the 21st of July. Tuesday morning is the one to circle. The wind goes completely glassy – a calm, zero wind condition. That’s a massive positive. The swell is 5ft from the S, with a period of 9 seconds and a combined energy of 365 (moderate to strong). This will be clean, with some real push. But be warned, this is a solid 5ft, which is getting into the intermediate zone. The water is much colder than normal for this time of year, sitting at 65°F, which is a notable 4°F below average. Crowds are “sometimes” an issue here, so a Tuesday morning glass-off might be your best bet for a quieter session.
After that Tuesday morning window, the quality drops again. The afternoons and the rest of the week see the wind turning cross or cross-on, and the conditions get lumpy. The 23rd of July has a 5ft swell from the E, but it’s a short 6-second period with a cross-chop, so it’s not going to be user-friendly.
The final weekend, the 25th and 26th, offers a glimmer of hope. The 25th has a 5ft swell from the S with a 7-second period and a gentle offshore wind from the WNW. The energy is moderate (179). It’s surfable, but it’s ordinary. You’ll get a wave, but it’s not the peak of the run.
Bottom line: If you can get out on Tuesday morning, the 21st of July, for that glassy, 5ft S swell, that’s your best shot. Everything else is a waiting game or a kite session. Stay patient.
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.
