The Lowdown
Alright, this is Rusty, checkin' in from the beach.
Right off the bat, we've got a bit of a flat spell headin' our way. The next week or so is lookin' pretty quiet, with only small, weak waves on offer. The water temp is sittin' at 70°, which is pretty much spot on for this time of year, so no surprises there.
The only real break on the radar for the whole 16-day window is Turtle Cove (a reef and point set-up). The first few days are a write-off. Tuesday the 25th has tiny 1ft waves from the SE with a weak energy reading of 37, and the surf is just poor. Wednesday the 26th morning is a little better with 2ft waves from the ESE and a light offshore wind, cleanin' things up, but it's still "very ordinary." The whole week through to the end of August is a grind of small, weak swell and onshore or cross-off winds. It's a bit of a bummer, honestly.
There's a little glimmer on Saturday the 29th afternoon with 2ft waves from the ESE and a light cross-off breeze, but it's still nothing to get excited about. Sunday the 30th morning goes glassy with a 2ft wave from the S, but the period is a short 6 seconds, so the energy is weak (54). We're lookin' at a real dry spell for a solid week.
Now, lookin' ahead to the second week, things start to get a bit more interestin'. On Tuesday the 1st of September, we see a jump in swell period to 15 seconds, which is a proper groundswell, but the height is still only 1ft from the SE. The energy is moderate (102) but the waves will be tiny. A long period swell like that on a point break can still produce a clean, lined-up wave, so keep an eye on it. The wind is offshore from the NW, so it'll be clean.
The real standout, the one you've been waitin' for, is Saturday the 5th of September. That morning we get 3ft of ESE swell with a solid 10-second period, and the energy bumps up to 210 (moderate). The wind is blowin' offshore from the W at 12 mph, which is a classic combo for Turtle Cove. That's the best surf on the forecast, and the guidance says the swell direction is right on the money for this spot. There will be crowds possible, but for a clean, chest-high wave with that offshore silk, it'll be worth it.
The next day, Sunday the 6th, jumps up in size to 3ft-5ft from the SSW, but the period drops to a weak 6 seconds and the energy is all over the place. The wind is workable, but the short period makes it messy. Monday the 7th of September brings the biggest swell of the period at 6ft from the SSW with a stronger energy reading of 452, but the period is still short (8 seconds) and the wind is onshore. The afternoon looks better with a 5ft SSW swell and offshore wind, which could be a fun, punchy wave for the experienced crew, but it's not quite as clean as the Saturday morning.
So, to wrap it up, don't bother paddlin' out this week. The only real window to get a proper session is Saturday the 5th of September. That's your day. Get on it.

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.
