The Lowdown
Alright, Rusty here again, same outlook but in feet and knots.
It’s a quiet stretch for Ditch Plains (Montauk). The next 16 days just don’t have much juice. Right now it’s all small, weak dribble with poor wind. The first real chance is about a week out, and even that’s a struggle.
This Sunday, 30 August: tiny 1ft swell out of the SE at 8 seconds (energy 23 – weak). Wind’s WSW at 12 knots as a cross-off, so it’s clean but there’s nothing to ride. That holds through Monday and Tuesday – same story, small SE pulses under 2ft, wind leaning cross-on. Not worth it.
We get a spike on Wednesday, 2 September: a messy 6ft from ESE, but that’s with rain and a screaming SSE wind at 22 knots straight onshore. Combined energy hits 216 (moderate), but it’s a blown-out, lumpy mess with a short period of 6 seconds. Thursday stays lumpy and cross-shore, swell dropping to 3ft.
Friday, 4 September is the first flicker. Morning offshore wind from the NW at 13 knots cleans things up. Only 2ft from the ESE at 7 seconds, energy just 61 (weak). It’s surfable – clean little waves – but very ordinary. That offshore trend holds through Saturday, but the swell drops to 1ft.
There’s a long flat spell from Sunday, 6 September, through midweek. Mornings stay clean with light north winds, but the swell barely registers. A few pulses of long-period E swell show Monday the 7th and Tuesday the 8th (11 seconds, energy 71 and 112), but the height barely hits 2ft to 4ft. On Tuesday the 8th, the swell jumps to 5ft out of the S at 6 seconds with onshore wind – energy at 213 (moderate), but it’s choppy and poor.
From the 9th onward, it’s back to small, weak, and cross-wind. Nothing cracks 3ft. The afternoon of the 13th shows a tiny 2ft S swell but with onshore wind again.
So for Ditch Plains, no day stands out. The best is Friday morning, 4 September – clean offshore wind and some 2ft peelers, but it’s small. The rest is a dud. Water temp is 70°F, about average for this time of year, so at least you’ll be warm waiting.
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.
