The Lowdown
Alright folks, Rusty here with a look at what’s coming up for Atlantic Terrace.
Right off the bat, I gotta be straight with you: the next week or so is lookin' pretty flat and frustrating. We’ve got a real dry spell on our hands. From Tuesday the 18th right through to Sunday the 23rd, it’s pretty much a write-off. The swell is tiny, mostly under 3 feet, and when there is a little bump of energy, the wind is just messing it up. We’re talking weak combined energy, barely hitting 80 or 90, and that’s just not gonna get you out of your seat. Expect a lot of small, choppy, onshore junk. Not worth paddling out for.
Now, things finally start to show a pulse of life on Monday the 24th. The morning wakes up with a cleaner vibe, light offshore wind from the NW, and a small 4 ft swell from the S. It’s not a bombshell, but the combined energy jumps to 132 – moderate, finally. Still, the afternoon gets chopped out again. That sets the stage for what looks like the first real highlight.
Tuesday the 25th morning is your best bet in this whole stretch. We get some clean conditions with that light N wind, and the swell bumps up to 4 ft from the SSW. The combined energy leaps to 284 – moderate energy, but on the stronger side of moderate. The wave comment says “expect good surf conditions,” and with that early morning glass, it’ll be clean. Just know that crowds are often here, so don’t expect to have it to yourself.
After that, we hit another rough patch Wednesday through Thursday with strong winds and onshore slop, even if the period gets long (15-16 seconds) – that’s a groundswell, but it’s all wasted by atrocious wind. The energy is there (367 on Thursday afternoon), but it’s all cross-onshore chop.
Then we get another chance on Friday the 28th morning. The S swell holds at 5 ft, and we get a clean cross-offshore breeze from the WSW. Combined energy is a solid 278 again, and the wave comment says “expect good surf conditions.” This is your second standout, though the afternoon gets a little marginal.
The last few days of August and into September are a mixed bag. We get some glassy mornings on the 30th, 31st, and September 1st, with clean conditions but small, average waves (2 ft to 4 ft). The energy is moderate, but nothing to write home about. The morning of September 1st has a glassy 4 ft from the SE, but by the afternoon it goes onshore again. Not terrible for a longboard, but don’t expect any barrels.
Overall, the best windows are Tuesday the 25th morning and Friday the 28th morning. Get out there early, and hope the crowds aren’t too thick.
Rusty.

Information about the Atlantic Terrace Surf forecast
The above surf forecast table for Atlantic Terrace provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Atlantic Terrace can be found by selecting the local surf guide option on the grey menu. Our Atlantic Terrace 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 (Atlantic Terrace) 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 Atlantic Terrace 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.
Atlantic Terrace is 39 km (24 miles) from New London. If you plan a vacation in Long Island New York, look for hotels and other accommodation in New London. New London has rooms for a wide range of budgets as well as car hire and transport links.
