The Lowdown
Hey, Rusty here. Let’s talk about Dumbea Left over the next 16 days. It’s a bit of a slow burner, with a lot of days you’ll want to skip. Water temp’s about average for this time of year, sitting around 72°F, so nothing special.
The first few days from Saturday August 22nd are a hard pass. Swells start at 6ft from the ESE with a short, choppy 8-second period. Wind’s a fresh cross-off at 35 km/h, keeping it clean, but the combined wave energy is weak at 478. Conditions are just poor. This pattern of small, weak swell and clean but unexciting surf drags on through Sunday and Monday, with sizes around 5ft dropping to 2ft.
Tuesday the 25th brings a shift to a longer-period SSW swell (15 seconds, 6ft), with combined energy up to 1658 (moderate). But it’s still marginal—wind’s strong, and something’s off with the tide. Not a goer.
Friday the 28th of August is the first flicker of hope. By afternoon, we get a tiny 2ft SSW swell at 13 seconds, but the wind goes glassy—dead calm at 5 km/h from the SSE. That gives us “good surf conditions” for the first time. Energy’s low at 260, but the glassy surface makes it rideable for a quiet session.
Now, lock in Wednesday the 2nd of September. That’s your big day. Morning swell hits 7ft from the S at 14 seconds, building to 8ft from the SSW by the afternoon with a 16-second period. Combined energy is huge at 3145 and 3109 (strong). Wind is light cross-off from the ESE at only 10 km/h, so conditions will be clean. This is excellent for experienced surfers—8ft is too much for beginners, and the swell direction matches the optimum for this reef. Expect proper lefts.
The 6th of September also shows a big, long-period groundswell—7ft from the SSW at 21 seconds, combined energy 4052 (very strong)—but winds are strong cross-off at 40 km/h. It’ll be clean, but that’s a beast for experts only, and the long period can make it wall up at a reef.
Bottom line: the first week is mostly a dud. Your one standout is Wednesday the 2nd of September. Hit it then, or miss the best of it. Rusty out.

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 Dumbea Left 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.
