The Lowdown
Alright, this is Rusty. Let’s have a look at what’s cooking for Turtle Cove.
Alright, straight up, the next 16 days are a bit of a mixed bag. There’s no real firestarter in this outlook, but there’s a couple of windows that’ll get you wet if you’re keen.
The first few days are pretty grim. We start on Monday, July 20th, with a tiny 3 ft SSW swell, and while it’s glassy in the morning, the afternoon gets hammered by a 12 mph cross-off wind. The energy is weak (81), and it’s just not worth paddling out for. Tuesday is even worse, with a choppy, onshore mess. A couple of days later, on Wednesday, July 22nd, things get a bit more interesting but more dangerous. The swell jumps to 8 ft from the SSW, with moderate to strong energy (1156). That’s expert-only territory. The wind is a cross-off, so it’ll be clean, but with that size and a 9-second period, it’s going to be heavy. Beginners need to stay on the sand that day.
After that, we go through a long stretch of small, weak surf. From Thursday, July 23rd, right through the end of the month and into early August, the swell drops back to between 1 ft and 4 ft. The combined energy is low, often under 100, and the winds are mostly cross-off or onshore. You’ll get a few glassy moments, like on the morning of Friday, July 24th with 3 ft SSW swell and glassy conditions, and again on the morning of Friday, July 31st with a flat 2 ft S swell and no wind. But these are barely rideable. It’s a long, quiet period.
The only real standout – and I’m using that word loosely – is the Wednesday morning, July 22nd session, if you are an experienced surfer and can handle that 8 ft. That’s the biggest spike in size for the whole forecast. The water temp anomaly isn’t flagged, so it’s about average for the time of year.
For the rest, it’s a waiting game. The morning of Tuesday, August 4th shows a small bump up to 4 ft SSW swell with clean conditions, but the energy is still modest (194). It’s not a total blank run, but there are large gaps of 4-5 days where nothing is worth getting excited about. The winds are often too strong and the swell too small to be fun.
All in all, if you’re a beginner, leave your board at home for most of this. If you’re a local charger, mark that Wednesday morning, July 22nd for a possible score, but be ready for a battle.
This is Rusty, signing off.

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.
