The Lowdown
Alright, folks, Rusty here. Let’s take a look at what’s happening at Ditch Plains over the next couple of weeks. I’ll be straight with you – it’s a bit of a mixed bag, but there are a couple of windows worth paddling out for.
First up, the water temp is sitting at about 73°, which is pretty much spot on for this time of year, so no surprises there.
We’ve got a real slow start. From now through the end of the week, it’s mostly tiny, weak swell with poor winds. Monday morning kicks off with a 4 ft S swell but a 22 mph cross-on wind making it lumpy and messy. That afternoon brings a bigger 6 ft S swell, but with onshore wind and questionable conditions, it’s not one to get excited about. Tuesday morning cleans up a bit with a light N cross-off breeze, but the swell drops to just 3 ft from the SSE, and the energy is weak (98). Wednesday morning is glassy with a tiny 2 ft SE swell (49 energy) – you might get a few knee-high runners, but it’s very ordinary.
Thursday through to the following Monday is pretty much a write-off. Swell stays below 2 ft through most of that stretch, with onshore and cross-shore winds. Not worth talking about.
Now, here’s where it gets interesting. On Tuesday the 25th (that's a week from now) , we finally see a pulse. The morning brings a 4 ft S swell with a clean, moderate offshore NW wind at 12 mph. The energy is moderate (101), and it’ll be rideable. But the standout is Tuesday afternoon: a 5 ft S swell, with a clean cross-off breeze from the WSW, and the combined energy jumps to 202 – that’s a solid, moderate push. It’s a reef break, so it’ll handle that swell well, but keep in mind the period is short (6 seconds), so the waves will be a bit weaker and more crumby than a long-period groundswell. Still, with clean winds, that’s the best we’ve got in this whole forecast.
Wednesday the 26th holds a decent 5 ft S swell but with a gentle cross-shore wind that puts a slight chop on it. Energy is strong (329), but the conditions aren’t as clean as Tuesday. It’s a consolation prize.
After that, the wind really turns on us. From Thursday the 27th through to the end of the month, it’s mostly fresh cross-onshore winds with moderate to strong energy swells (200 to 652 energy), but the chop and lumpy conditions will make it a battle. There’s a 4 ft SE swell on Friday the 28th morning with a 13-second period, which is long-period groundswell – that would be a gem at a point or reef, but at Ditch Plains with a fresh cross-shore wind? It’ll be bumpy and a bit of a mess. Not our day.
The very end of the run, on Tuesday the 1st of September, shows a return to clean offshore NW wind, but the swell is tiny at 1 ft. Not much to work with.
So, the honest call: if you’re looking for the one session to mark on the calendar, make it Tuesday the 25th afternoon. That 5 ft S swell with clean cross-off wind is your best bet. The Tuesday morning session is also solid but smaller. Everything else either has poor wind, tiny surf, or both.
We’ve got a long gap of poor to flat surf at the start, and another stretch of messy, windy conditions in the second week, but that one Tuesday window is a true standout. Don’t sleep on it.
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.
