The Lowdown
Alright, this is a tough one to call, folks. Let’s get real about Ditch Plains for the next couple of weeks.
First off, the water’s sitting at a pretty normal 72°, so no surprises there. But the real story is the complete lack of surf. For the first 12 days of this forecast window, from the 18th of August right through to the 29th, it’s a total desert. We’re looking at tiny, weak, and messy waves that just aren't worth paddling out for. The combined swell energy is mostly in the double digits, peaking at just 103 (moderate) on the 22nd, but it’s attached to a short-period, choppy onshore wind. It’s pretty heartbreaking, honestly.
The one and only glimmer of hope comes on the 30th of August. Sunday morning at Ditch Plains, we’ll see a bump in the swell to 4ft from the SE. That’s a long-period groundswell of 12 seconds, which is a beautiful thing for a reef break like this. The combined energy jumps to a strong 537, and with a clean, cross-off wind from the NNE, the conditions will be glassy. This is a window for the intermediate crew. Just be aware that with that long period, it might break a bit straight on the sandbars, but on the reef, it should have some shape. The calls for this weekend-out are promising but less certain this far out.
After that, the 31st of August has a smaller 4ft SSW swell, but a clean cross-off wind again, making it a decent option for a longboard or a fun grovel session. The energy drops to a moderate 153.
So, to sum it up: this is a long, flat spell that finally breaks on the 30th of August. That’s your standout. Get out there Sunday morning for the cleanest, most powerful waves of the whole outlook.

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.
