The Lowdown
G’day, Rusty here. Let’s talk about Turtle Cove for the next couple of weeks. It’s a slow burner, so don’t go rushing out the door just yet.
The first real chance to get wet isn’t until Wednesday morning, July 29th. There’s a 7ft swell from the SSE, but the wind is blowing onshore from the east at 12 mph, and with moderate rain, it’s gonna be a mess. The combined energy is strong at 858 (strong). The afternoon cleans up though – a 5ft SE swell, with a light offshore wind from the SW at 6 mph, and the wave energy is 309 (moderate). That’s the first window, but it’s not a standout.
Thursday the 30th gives us a 5ft S swell in the morning, with a light onshore breeze from the NE. It’s surfable but nothing special. The water temp is 68°F, which is a bit colder than usual for this time of year (anomaly of -2°F), so you’ll want a wetsuit.
The big one, the one you need to be ready for, is Monday, August 3rd. That morning, we’ve got a clean 7ft S swell hitting the reef and point, with a proper offshore wind from the W at 6 mph. The combined energy is 936 (strong), and the conditions are glassy. This is serious swell – over 5ft, so it’s getting too big for beginners, but for the intermediate crew, this is the session. The direction is straight from the south, which lines up perfectly with the optimum SE swell direction for this spot. The afternoon still holds a 6ft S swell with clean offshore winds. It’s a wait, but this is the highlight.
Tuesday, August 4th is still worth a look – a 5ft S swell in the morning with light cross-offshore winds from the NNW. It’s clean and the energy is 241 (moderate), but the swell drops in the afternoon.
After that, it’s a long, slow fade. From Wednesday, August 5th through to the 11th, the swell drops below 3ft for most of the time, and the wind is either cross-shore or onshore, making it choppy and lumpy. There’s a moment on Thursday, August 6th with a 6ft SSW swell, but it’s cross-offshore and the energy is 251 (moderate), so it’s messy. Honestly, after that Monday, you’re better off waiting for the next swell.
So, to wrap it up: the first week is a slow grind until Wednesday the 29th, but the real gem is Monday, August 3rd. That’s the one to mark on the calendar. For the rest of it, the conditions look more interesting for a kite surfer than a paddle surfer, especially on those windy days. Keep an eye on it, the forecast can change.
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.
