The Lowdown
Alright, folks, Rusty here.
First up, let’s be real. We're looking at a pretty quiet 16 days ahead. There are long stretches where you’ll be better off waxing your longboard just in case, but don't expect much. The first bit of anything rideable doesn't show up for a while.
The water temp is sitting at a very average 72°F, so nothing weird going on there for this time of year at Ditch Plains.
The first real flicker of hope is on Monday the 17th of August, but only in the morning. We get a bit of a boost with some S swell pushing up to about 4ft, and the combined energy hits a moderate (203). It’s still small, but the wind is light offshore from the NNW, so it should be clean. Don't get too excited though—it’s short-period stuff around 8 seconds, so expect fat, crumbly waves rather than any real punch. It’s the best we’ve got for that day, but that’s not saying much.
After that, it’s pretty much a wasteland again. We get another sniff on the morning of Thursday the 20th with a 4ft S swell, light offshore wind from the NNE, and clean conditions. The energy is weak (97), so you’ll be paddling for nothing, but if you’re desperate, you might find a knee-high ripple.
The only other day worth mentioning is way out there, on Thursday the 27th of August. The swell jumps up a bit with an E swell around 5ft to 6ft, and the energy climbs into the moderate range (214 to 249). But here’s the catch—the wind is onshore and cross-onshore all day, making it choppy and messy. Plus, that 6-second period is just windswell junk. It won’t be pretty.
So, to sum it up: there is no true standout here. The best on offer is the clean, small surf on Monday morning the 17th or maybe a desperate paddle on Thursday the 20th. Everything else is flat, blown out, or just not worth the effort.
Stay patient, the waiting game is all we’ve got.
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.
