The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this outlook is a tough one. We're looking at a long, dry spell for the Montauk area, specifically at Ditch Plains. The wait for anything worthwhile is painful.
The water's sitting at about 72°, which is pretty average for this time of year, so no surprises there.
Let's walk through it. This Friday morning, the 21st, is a write-off. We've got a strong 28 mph cross-shore wind from the NE, turning a 5 ft swell into a complete mess. The combined energy is a moderate 111, but it doesn't matter with that wind. It's a no-go.
The rest of this week and into the next is a big ol' gap of nothing. Saturday the 22nd drops to a knee-high 3 ft, and the wind is still cross. Sunday the 23rd is flat. Monday the 24th sees a tiny bump of 3 ft with a 6-second period from the SSE, but the wind is cross-off, so it might be clean. The combined energy is a moderate 112, but these waves are small and weak. Not worth getting excited about.
The whole second week, from the 25th of August right through to the 5th of September, is a desert. We get a few small pulses, like a 2 ft on the 25th with a very long 11-second period from the SE, but the energy is weak (47). The wind is clean, but it's just not enough size. The end of the window on the 5th of September shows a bit more energy with 3 ft from the SSW, but the period is a short 5 seconds and the wind is a fresh 22 mph onshore. It's just lumpy, choppy, and poor.
There is not a single standout day in this 16-day forecast. The only two days that even get a "surfable" rating are the 29th of August and the 2nd of September, and even then, they're described as "very ordinary." The 29th has a clean 2 ft from the SE with a light offshore wind, and the 2nd of September is similar with a 1 ft from the SE and a 12 mph offshore wind. Neither is worth paddling out for.
This is a blank run. It's a tough patch, but that's the way it goes sometimes. Forecasts can change, so keep your eyes peeled, but as it stands, leave the board in the car.
Rusty.

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.
