The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Duppys over the next couple of weeks.
Straight up, it’s a rough start. The next week or so is looking pretty flat and messy. We’ve got a long stretch of small, weak swell and onshore or cross-off winds that are just killin’ any chance of a decent wave. The water temp is sittin’ around 84°, which is pretty much bang on average for this time of year, so no surprises there.
The first real sign of life doesn’t show up until Saturday the 15th of August. Overnight, the swell jumps up to 8ft from the ENE with a period of 8 seconds, and the combined energy hits 728 (moderate). That’s a solid increase, but the wind is still cross-off from the ENE at 22 mph, so it’s gonna be lumpy and tough. It’s a beach-and-reef setup, and with that much wind and swell, it might actually be more interesting for the kite surfers than us paddle guys. The wave quality is still poor, so it’s not a standout.
Sunday the 16th of August is where we get the best of the run. The afternoon brings a 8ft swell from the ENE with a long period of 12 seconds. That’s groundswell, folks. The combined energy is a hefty 1701 (strong). This is a serious amount of juice. The wind is still cross-off from the NE at 19 mph, so it’s not glassy, but it’s clean. Duppys is an advanced reef break, and with this size, it’s strictly for experts. Waves over 8ft are no joke. The long period means it’ll have power and shape, but on a reef, it’ll be shifty and powerful. Keep your wits about you.
After that, it drops back down. Monday the 17th has a smaller 4ft swell from the ENE, but the wind swings to a cross-off from the SSE, which is a bit more favourable. The energy is 404 (moderate). It’s still marginal, but there’ll be a few lumps if you’re desperate.
The rest of the second week fades back into tiny, weak surf with clean but onshore winds. The 21st of August has a brief flicker of 3ft from the ENE with offshore wind, but it’s small and ordinary.
So, the standout here is Sunday the 16th of August. That’s your best bet. Big, powerful, expert-only groundswell at Duppys. It’s a solid window, but the wind is the only thing holding it back from being truly epic.
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.
