The Lowdown
Alright, let’s talk in feet and miles per hour. Things are pretty quiet for a stretch, but there’s a big pulse coming in the second week that’s worth a look.
Starting off, Duppys (reef) is flat. From Friday, 21st August, through the rest of the month, we’re seeing tiny waves around 0.7 ft to 1 ft from the north, with short periods under 8 seconds. Water temp is about average for the season. The wind is a cross-off from the east, keeping the surface clean, but there’s no power – the combined swell energy is barely registering (10 to 15). Not surfable.
That quiet stretch runs all the way through the end of August and into early September. Big gap with nothing to recommend. It’s a dead spell.
Then, late on Friday, 28th August, things start to move. The swell picks up to 5 ft from the east-northeast, with a period of 7 seconds, and the energy jumps to 309 – moderate. Still, conditions are marginal, and the wind is a fresh cross-off, so it’s messy. By Saturday morning, 29th August, we’ve got 8 ft from the east-northeast, period 8 seconds, and strong energy at 757. The wind is still fresh cross-off, so quality is poor.
Here’s the standout. Saturday afternoon, 29th August – Duppys gets a solid 10 ft swell from the east-northeast, with a period of 10 seconds. The combined energy hits a massive 1609, which is very strong. The wind is cross-off from the east-northeast at 18 mph, but the forecast says wind and tide are favorable. That 10 ft is huge – expert territory only. It’s a reef break, so that long-period groundswell will shape up well, but it’s going to be heavy. Crowds are possible, so get there early.
After that, it drops off fast. Sunday, 30th August, back to 0.7 ft. Window closes quickly.
There’s a small blip on Saturday, 5th September, with 7 ft from the east-northeast, period 8 seconds, and moderate energy (493), but the wind is cross-off and conditions are marginal. Not a true standout.
For experts, that Saturday afternoon, 29th August, is your shot. Otherwise, it’s a long wait.

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.
