The Lowdown
Alright folks, Rusty here. Let’s break down what’s happening for the next couple of weeks.
It’s been a quiet run leading into this forecast, and honestly, things don’t look like they’re going to fire up much for a while. The first real stretch of surfable waves is a long way off, so we’re looking at a gap of nearly a week with very little to get excited about. The water temperature is sitting at 84°F, which is about 0.5°F warmer than average for this time of year—so nothing too unusual there, just your typical warm tropical bath.
The only spot that’s on the radar here is Duppys, a reef break that needs a precise N swell to really get going. It’s a fairly consistent spot, but for the first several days, swell heights are tiny—mostly 0.7ft to 1ft from the NNE or N, with combined wave energy readings in the low double digits (40 and below). That’s weak energy, and the wind is mostly cross-off or cross-shore. It’s clean, but there’s simply no power in the water. For a few days after that, the swell picks up slightly but the period is short (7–8 seconds) and the conditions are still marginal. The best chance we get is on Monday afternoon, 24 August. That’s when a long-period groundswell from the ENE rolls in with 7ft of swell and a period of 12 seconds, pushing combined energy up to 1432—that’s strong, proper energy. The wind turns light offshore from the ESE, so the waves should be clean and lined up. This is really for the experienced crew, though, because 7ft on a reef break is no joke. The swell direction is from the ENE, which is not the absolute optimum N that Duppys prefers, but it’s close enough to get some decent shape. Crowds are sometimes a thing here, so you might have a few others out, but with the size and the quality, it’ll be worth it.
After that, Tuesday afternoon, 25 August sees a drop to 5ft NE swell with moderate offshore wind, but the energy is still moderate (400), and the comment says “expect good surf conditions.” It’s not the standout, but it’s a solid backup. The rest of the fortnight falls back into tiny, weak surf with cross-off winds and combined energy readings mostly under 20. Not much to get excited about.
So, the standout is clearly Monday afternoon, 24 August at Duppys. That’s the one to circle on the calendar. Everything else is a flat spell or marginal at best. If you’re a beginner, stay away from that Monday—it’s too big. For everyone else, get ready for a proper session.

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.
