Dumbea Left Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks. We've only got one spot in the mix, Dumbea Left, so that's where all our focus is going. It's an advanced reef break, fairly consistent, and it likes the swell from the SSW, which is exactly what's coming. It's a bit of a slow start, so don't expect much right away.

We're looking at Monday the 7th and Tuesday the 8th with small, marginal waves. Monday morning has a clean 4ft SSW swell with a 13-second period, but it's just not doing enough to get excited about. The wave energy is moderate (803). The water temp is about average for this time of year. Tuesday stays small and the wind gets messy, so those days are write-offs for any decent surf.

Wednesday the 9th sees a bump in size to 6ft, but the wind is howling onshore from the SSW and S, making a mess of things. Thursday the 10th is much the same – lumpy and choppy. Friday the 11th brings a weird one: a tiny 3ft swell but with a massive 22-second period, giving a strong wave energy (1293). That's a super long-period groundswell, which at a reef break like Dumbea Left could produce some very long, walling lines, but the cross-shore wind is fresh and messy, so don't expect any sort of quality.

Now, here's the standout. Saturday the 12th. We're looking at a solid 12ft SSW swell with a 17-second period. That's a whole lot of energy (7581). This is proper big-wave territory – over 8ft, so it's experts only. The wind is cross and strong at 22 mph, but the report says wind and tide are favorable, which is a big call. This could be a session for the brave, with some serious, powerful waves. It's the best on offer, but it's a big, dangerous beast.

Sunday the 13th is still pumping with an 8ft S swell, but the wind is a stiff cross-offshore from the ESE at 22 mph. That'll clean things up, but it's still a big, powerful wave for advanced surfers only. The energy is still high (2542). This is another potential standout if you can handle the size and the wind.

Monday the 14th keeps the size up around 8-8ft, with a strong cross-offshore breeze. The wave energy is strong (3318). It's still big and clean, but the wind is cranking at 25 mph. Tuesday the 15th drops a little to 7ft, but the wind is still fresh and cross-offshore. It's clean, but the quality is marginal.

After that, things start to fade. From Wednesday the 16th onward, we see a drop in size and a return of lumpy, cross-shore winds. Thursday the 17th is a write-off. Friday the 18th shows a pulse back up to 7ft, but with messy winds. Saturday the 19th and Sunday the 20th have some clean windows with a cross-offshore wind, but the size is dropping and the energy is fading.

Then, looking ahead to Monday the 21st of September, there's a glimmer. A 7ft SSW swell with a 12-second period and a light cross-offshore breeze from the east at only 9 mph. The energy is moderate (1384), and the wind is gentle. This is a long-range call, so don't bank on it, but it's the best-looking, most manageable window in the second week for the more advanced crew. Tuesday the 22nd looks like it gets messy again with strong cross-shore wind.

So, to sum it up: if you're an expert and you want a proper, heavy session, Saturday the 12th is your day, but it's a big one. For a slightly more manageable but still solid and clean wave, Sunday the 13th and Monday the 14th are your best bets. Everything else is either too small, too windy, or too messy.

Stay safe out there.

Rusty.
