The Lowdown
Alright, let’s break it down. This is a tough stretch for Dumbea Left, the reef break. The first week is mostly a bust. From Monday the 10th through to Friday the 14th, the wind is all over the place – cross and onshore – making for lumpy, choppy conditions. The swell is small and weak, with combined energy mostly under 200 (192) and never really getting clean. Not much to work with.
We get a tiny window on Saturday the 15th morning. The swell is 6ft from the SSW, but the wind is a cross-shore from the SSE at 12 mph, and the combined energy is moderate at 754. It’s still marginal, not what you’d call a good day.
The only real standout, the one I’d paddle out for, comes at the end of the second week. Look at Monday the 17th afternoon. The swell is 4ft from the SSW, but the wind is a clean cross-offshore from the SE at 22 mph. The combined energy is strong at 1334. That’s a long-period groundswell at 14 seconds, which will power up the reef nicely. It’s an advanced spot, so it’s not for the groms. The water temp is about 72°, which is normal for the season.
Then Tuesday the 18th is the big one. Morning has 7ft from the S, a 14-second period, and a cross-offshore wind from the ESE at 22 mph. Combined energy is very strong at 2215. That’s big, powerful, clean surf. With waves over 8ft, it’s strictly for experts. The afternoon is similar, 7ft from the SSE, still very strong energy (2181), and clean. This is the best of the run, but it’s far out, so treat it as a promising but less certain call.
After that, it fades. Wednesday the 19th and Thursday the 20th are still clean but smaller. From Friday the 21st onward, the wind turns onshore and the quality drops off completely. The last few days are all poor conditions.
So, the one standout window is Monday the 17th afternoon through Tuesday the 18th. If it holds, that’s the time to go. The crowds are listed as “sometimes,” so expect a few other surfers.

Information about the Dumbea Left Surf forecast
The above surf forecast table for Dumbea Left provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dumbea Left can be found by selecting the local surf guide option on the grey menu. Our Dumbea Left 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 (Dumbea Left) 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 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.
