The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Turtle Cove over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a real slow start. The next few days are flat or pretty much no good. Friday the 17th and Saturday the 18th are all tiny, weak lumps with poor conditions. We’re talking about a gap of a few days with nothing worth paddling out for.
Sunday the 19th is where things start to look a little more interesting. The morning has a little spike of 5ft swell from the SSW, but it’s short period at 7 seconds, and it’s too blown out. The afternoon is a step up though – 4ft from the SSW, period still short at 7 seconds, but the wind goes offshore, cleanin’ it up. The combined energy is moderate at 159 (units). It’s surfable, but it’s not gonna be one for the albums.
The real standout in this forecast is Wednesday the 22nd afternoon. We’re lookin’ at a solid 7ft swell from the south, with a period of 10 seconds, and the wind is cross-offshore. The combined energy jumps right up to a strong 752 (units). Now, this is a big one – 7ft is expert territory, so if you’re not comfortable in that size, stay on the beach. It’s a reef and point break, so that longer period (10s) will be workin’ nicely on the take-off. For those who know what they’re doin’, this is the day to circle.
Thursday the 23rd morning is still a decent shout with 4ft from the south (8 seconds) and a light cross-off breeze, giving it a combined energy of 262 (units). It’s a solid option if you missed the big one.
After that, the swell drops off again. The rest of the week and into the next (starting Monday July 28th) is pretty average. There’s a couple of mornings with glassy conditions, like Friday the 24th morning and Monday the 27th morning, but the swell is small and the energy is low. The 27th has a 4ft south swell with an 8-second period and glassy wind – that’s a nice little window for a quiet session, just don’t expect much power.
The water temp is a bit colder than normal for this time of year, around 68°F with a -2°F anomaly. So you might want a slightly thicker spring suit.
Overall, the real magic is that Wednesday the 22nd afternoon. It’s big, it’s punchy, and it’s clean. The rest is a bit of a waiting game. It’s been a quiet spell but it won’t stay poor forever.
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.
