The Lowdown
Alright, Rusty here. Let’s break it down in feet and knots.
Right now, we’re looking at a pretty flat and lackluster stretch ahead for Turtle Cove. The first week is mostly a write-off, so if you’re itching to paddle out, you’ll need patience. There’s a big gap of nothing special until we start seeing a pulse of energy rolling in from the southeast towards the end of the first week and into the second.
Starting from Monday the 24th, we’ve got tiny, weak swell with poor conditions. Wind is mostly cross or cross-off, but the swell is too small and short-period (6 seconds) to do anything worthwhile. The combined energy is weak (85) and the forecast screams "poor surf conditions." That theme holds through Tuesday and Wednesday – waves stay under 3 feet, weak, and unappealing. Thursday the 28th sees a slight bump, with a 3ft south swell but onshore easterly winds mess things up in the morning. By Friday afternoon, there’s a glimmer: a 2ft SE swell with cross-off wind, but it’s still very ordinary.
The real potential shows up on Monday the 31st of August. It’s still small, with a 1ft to 1ft swell, but here’s the kicker: the period jumps to 19 seconds. That’s a very long period groundswell, and the wind turns offshore (W and WSW). Combined energy picks up to moderate levels (78 to 103). Conditions say "clean" and "gentle offshore." For Turtle Cove, a reef and point, this long-period energy should wrap in nicely, offering clean, lined-up waves even if they’re small. It won’t be big, but for a patient surfer, these will be glassy, fun runners.
Then, we skip past some messy, blown-out days from a heavy rain and strong wind system on the 3rd of September (don’t bother). The standout window comes on Wednesday morning, the 2nd of September. Swell bumps up to 3ft from the SE with a 13-second period, combined energy is strong (339), and we get cross-off winds from the NW. The forecast even says "expect good surf conditions." That morning will be the best of the entire period – clean, punchy, and with enough energy for some proper rides.
Friday the 4th of September also looks promising: morning offshore wind from the west with a 3ft, 12-second SE swell and moderate energy (209). Clean conditions again. After that, it fades back to tiny, onshore slop.
So overall: don’t hold your breath this week. The best two windows are Monday the 31st of August morning (small but super clean and long-period) and Wednesday the 2nd of September morning (best overall size and quality). Get the wax on for those.
Stay stoked.

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.
