The Lowdown
Alright, let’s talk in feet and miles per hour for the imperial crew.
It’s gonna be a slow start at Duppys, with a whole lot of flat and messy days before a late-play shines through.
From now through the middle of next week, you’re looking at tiny 1-2ft swell from the NNE with a period around 10-12 seconds, but the energy is weak – combined readings never crack triple digits. Wind is from the east at 15-22 mph, cross-off to offshore, so it’s clean but gutless. Not worth paddling out for.
Tuesday the 18th of August offers a small window: a 4ft swell from the ENE with a short 8-second period, combined energy hitting 200 (moderate). Wind is a light 9 mph cross-off, so it’ll be clean. At 4ft with short period, it’s a fun-sized wave for the keen, not a standout.
The real deal is Monday the 24th of August. Morning brings a 4ft groundswell from the ENE with a long 13-second period and combined energy of 682 (strong). A fresh offshore wind from the east at 22 mph keeps it clean and lined up. This is a reef, so that long period will wrap in nicely – good shape, real power. It’s an advanced wave at this size. The afternoon sees it jump to 7ft from the same direction with an 11-second period and energy at 937 (very strong). That’s expert-only territory, especially with the wind going cross-off. This Monday session is your best bet across the whole forecast. Crowds are possible here, so get there early.
After that, Tuesday the 25th flattens out again, and you’re back to 0.3-0.6ft slop with moderate to fresh cross-off winds all the way to the end of the month. A small pulse on the 30th of August brings 4ft from the ENE with a short 7-second period and energy of 117, but it’s windswell and not worth chasing.
First 9 days are mostly a bust. Save your energy for Monday the 24th – that’s the one to circle. Water’s 84°F, about average for late August, so it’s nice and warm.

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.
