The Lowdown
Alright, buddy, Rusty here. Let’s cut to it – this 16-day stretch is mostly a bust, but one day is a proper monster.
From now through the 24th, it’s a barren run. Wave heights are way down, mostly under a foot, and the energy is pathetic (combined energy almost always under 20). The trade winds are cranking from the east and north-east, blowing 15 to 20 mph or more, just ruining any chance of a decent peak. Don’t bother suiting up.
But hold onto your leash, because Monday afternoon the 24th is wild. Duppys is looking at a massive 13-foot swell coming from the ENE, with a 13-second period. That’s raw power – the combined energy hits a staggering 4679. The wind is a clean cross-offshore from the NE, so those walls should be clean and take shape. This is for experts only – 13-foot waves are no joke, and this exposed reef will be handling a lot of water. The direction matches the break’s sweet spot perfectly. This is the only real window in the whole forecast.
After that one almighty pulse, it’s straight back to flatness and breezy, crappy conditions right through to September 2nd.
Water temp is about average for this time of year, nothing unusual.
To sum it up: you’ve got a week of nothing, then one day of absolute, heavy-duty glory on the 24th at Duppys. If you’ve got the experience, that’s where you need to be. The rest of it? Not worth the drive.
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.
