The Lowdown
G'day, Rusty here. Look, I’m gonna be straight with you – this 16-day stretch for the region is a tough one. The water is sitting at a warm 84°F with a temperature anomaly of 0.7°F, which is pretty much average for this time of year, so no surprises there.
The story starts with a real flat spell. From Wednesday the 19th right through to Monday the 24th of August, it’s a wasteland. We’re talking tiny, weak swell with poor conditions day after day. The energy is next to nothing, barely registering a 10 or so for most of that time. The wind is either cross-off or offshore, but with no swell to work with, it’s just a tease. Monday the 24th is a total write-off with zero wave energy.
Then on Tuesday the 25th of August, things get a bit mental. The swell jumps up to 12ft from the ENE, with a period of 11 seconds and a massive combined energy of 2475 – that’s serious oomph. But for Duppys, a reef break, this is way too big. It’s an advanced spot, but even for the experts, that’s a washing machine. The wind is cross-off, not ideal for that size. This is a day for the heavy hitters only, and only if they’re feeling brave.
After that, it drops off again. From Wednesday the 26th to Saturday the 29th of August, we’re back to tiny, inconsistent waves with energy levels in the single digits or low twenties. Not worth paddling out for.
Now, the one bright spot. Sunday the 30th of August afternoon shows a pulse of 6ft from the ENE, with an 11-second period and a combined energy of 695. That’s a moderate, solid swell. The wind is offshore from the ESE at 12 mph, which will keep it clean. Duppys is a north-facing reef, and this ENE swell will wrap in nicely. The crowds are listed as “sometimes” here, so you might get a few out, but it’s a quality wave. This is the standout of the whole period. Monday the 31st of August morning still has some 4ft ENE swell with 265 energy and offshore wind, so the morning session will be good, but it fades quick.
From the 1st of September onward, it’s back to tiny, clean but flat conditions. Not much to chase.
So, the call is: don’t bother until Sunday the 30th of August afternoon. That’s your window. The Tuesday the 25th is a monster, but only for the pros. The rest is a long blank run.
Rusty.

Information about the Duppys Surf forecast
The above surf forecast table for Duppys provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Duppys can be found by selecting the local surf guide option on the grey menu. Our Duppys 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 (Duppys) 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 Duppys 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.
