The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. The next couple of weeks aren’t gonna have us pulling any all-nighters for a dawn patrol. It’s a real quiet stretch for Ditch Plains, so we gotta hunt for the small windows when the ocean gives us something clean to work with.
Right off the bat, we’ve got a couple of those windows. Tuesday morning, the 18th, the wind goes glassy with a touch from the NNE. That’s our best bet early on. We’re looking at a small 3ft swell from the SSE with a 7-second period. It’s not going to blow your mind, but on a glassy morning like that, you can find some clean little corners on the inside. The water is sitting at 73°, which is about normal for this time of year. The energy is weak, only around 85, so it’s a groveler’s session, but the lack of wind makes it worth a paddle.
The following morning, Wednesday the 19th, is also worth a look. The wind goes glassy again, this time straight offshore from the W. The swell is a touch smaller, 2ft, and the energy is even weaker at 50. Still, on a clean, glassy morning, there’s always a chance to snag a fun one if you’re willing to work for it. We’ve also got Thursday the 20th with a light cross-off breeze and a 2ft swell, but it’s really those two mornings that are the pick of a very average bunch.
Now, we’ve got a long stretch of nothing after that. From Friday the 21st right up until the end of the month, it’s mostly junk—cross-shore winds, chop, and tiny surf. There’s a pulse of energy on the 27th (a couple of storms passing by), but it’s coming with strong winds, the swell direction isn’t ideal, and the period is short and jumbled. It’s going to be a mess, and honestly, it’s more interesting for the kite crowd than for us paddle surfers.
We do get a brief reprieve on the 28th, a Friday morning with a 2ft SSE swell and a clean cross-off breeze, but it's hardly a standout. The energy is moderate at 157 but the size just isn’t there.
There is a glimmer of hope way out there, over a week away. The 27th of August afternoon holds the biggest swell of the period at 5ft, but period is 12 seconds and from the ESE. The wind is howling out of the SW, which is cross-shore. It's a classic case of "plenty of water moving, but no shape." So, that’s a no-go for a surf report. By the first of September, we’re back to small, weak, and windy.
So, to sum it up, we have two mornings next week, Tuesday and Wednesday, that are worth getting up for. They’re not classics, but they’re clean. After that, you can leave the board in the car. The long-range stuff looks promising on paper, but the conditions are all wrong. It’s a waiting game, boys and girls. That’s the blunt truth of it.
Rusty, signing off.

Information about the Ditch Plains Surf forecast
The above surf forecast table for Ditch Plains provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ditch Plains can be found by selecting the local surf guide option on the grey menu. Our Ditch Plains 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 (Ditch Plains) 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 Ditch Plains 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.
Ditch Plains is 38 km (24 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.
