The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at the charts for the next couple of weeks. I'll be straight with you: it’s a bit of a lean stretch for Ditch Plains. We’ve got a long gap of small, messy waves before anything worth paddling out for shows up on the radar.
The 16-day window kicks off with a whole lot of nothing. From the 15th through the 24th, we are looking at a real dry spell. Most days are showing tiny surf with poor conditions – onshore slop, cross-shore chop, and just not enough energy. The water temp is sitting at 72°, which is about 0.4° above the norm, so pretty average for this time of year and right in that comfortable range. Don't expect any magic here.
The first real pulse of energy arrives on the 17th, but it’s a bit of a tease. While the swell bumps up to about 6ft, the wind on Monday morning is a strong cross-onshore, making it a complete mess. The afternoon is the one silver lining that day. The wind swings around to a light cross-offshore, cleaning it up nicely, and the combined energy jumps to a moderate 643. That’s the standout window in the first week – the biggest, cleanest surf we’re going to see for a long while. That’s your best bet if you’re jonesing.
After that, it’s back to small and unimpressive. From the 18th right through to the 22nd, we’ve got ankle-biters and knee-high slop. The swell drops back under 3ft with weak energy readings, all under 100. Most of it is short-period windswell. There’s a brief bit of glass on the morning of the 23rd, but the swell is barely there, so don’t get too excited.
The second week picks up a little, but it’s still nothing to write home about. Around the 25th, we get another push, with the swell coming in around the 3 – 4ft mark and that clean offshore flow, but the period is short, only 6 seconds. It's surfable but not great. Then on the 27th, Thursday morning, we've got another glassy window with a 2ft SE swell and a period of 12 seconds. The energy builds a bit to 174, which is moderate. That looks like the cleanest option in that stretch, but it’s still pretty small.
So, let's be honest. The standout is that Monday afternoon on the 17th. It’s got the size and the clean conditions. The other notable mention is Thursday morning the 27th – it’ll be glassy, but you’ll be working for tiny waves. Everything else is a whole lot of paddling for nothing, so maybe have the kite gear ready if the wind kicks up.
This looks like a stretch where patience is your best friend.
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.
