The Lowdown
Alright folks, Rusty here. Let’s take a good look at what’s heading our way at Dumbea Left over the next couple of weeks. It’s a bit of a slow burn at the start, but there’s some serious potential brewing for the more experienced crew later on.
The first few days are pretty grim. We’ve got a solid SSW groundswell coming in on Monday the 17th, pushing around 6ft with a long 16-second period, and the combined energy is a hefty 2077 (moderate to strong), but a howling 22 mph cross-shore wind from the SE is just wrecking it. The water temp is about average for this time of year, but the lineup will be a messy, lumpy battle. Tuesday the 18th sees the swell jump to 10ft from the S, period dropping to 12 seconds, with energy at 4371 (strong), and it’s cleaner with a cross-off shore wind. But at that size with a fresh breeze, it’s a beast only for advanced surfers, and the forecast is marginal at best. The rest of that week and into the weekend stays pretty average – some clean conditions but with weaker, shorter-period swell and scores that don’t get the heart pumping.
The real standout, the one that makes it worth waiting for, is Tuesday the 25th of August. The morning is absolute perfection for the experienced surfer. We get a clean 4ft SSW groundswell with a long 14-second period, and a light breeze from the E at only 6 mph. The energy is a solid 1137 (moderate). It’s glassy, it’s clean, and guidance says this is a reef break that loves swell from the SSW. For someone who knows what they’re doing, this is the session to circle on the calendar.
We get another glimmer of hope on Thursday the 27th. The morning is glassy, dead calm, with a clean 6-7ft SSW swell, period of 15 seconds, and combined energy of 1942 (strong). The conditions are described as excellent for experienced surfers. That’s a big, powerful, lined-up wave, but with that size, it’s not for the faint of heart or the beginner.
After that, the final days of August and into September look like they’ll hold some cleaner, chest-to-head-high swell from the SE, but the winds pick up again, keeping things from turning truly epic. The very end of the forecast period into September 1st has some cleaner hopes, but it’s a way off.
So, the best bet on the whole forecast? Mark down Tuesday the 25th of August for a quiet, clean session. For the brave, the glassy Thursday the 27th morning is also a serious contender, but be ready for a bigger, more powerful wave.
Stay salty,
Rusty

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.
