The Lowdown
Alright, let’s get into it. I’m lookin’ at the next couple of weeks and to be honest, it’s a bit of a mixed bag for the region. There’s some decent swell on the way, but there are also some flat spells and windy stretches to work around. Let’s break it down.
First up, we’re looking at Dumbea Rights, a reef break that’s consistent and exposed to the swell. The water temp is sittin’ around 73°F, which is about what you’d expect for this time of year, so no complaints there.
The week starts off with a bit of size. Tuesday the 18th, you’ve got a solid 10ft swell from the SSE with a period of 12 seconds, and the energy is pumping, comin’ in at 4248 – that’s a lot of power. The wind is a cross-off from the ESE at 25 mph, so it’s gonna be clean but pretty strong. This is not one for the beginners – it’s too big. This is for advanced crew only. The quality is a bit marginal with the tide and the wind strength, but there’s no denyin’ the swell is there. That afternoon it drops a bit to 8ft, still clean but same strong wind story.
Wednesday the 19th stays in the game with a 7ft swell in the mornin’ from the SSE, period droppin’ to 10 seconds, energy at 1622. Still a bit of a puff in the wind at 22 mph from the ESE, but it’s cross-off and clean. The afternoon sees a slight drop to 7ft from the SE, period 11 seconds. Again, not a day for the learner, but there’s push.
Thursday the 20th brings the swell down under the 6ft mark – 6ft in the mornin’ from the SE, period 8 seconds, energy down to 719. Wind eases to a moderate breeze at 16 mph, still cross-off and clean. It’s gettin’ more manageable but also less excitin’. Friday the 21st bumps back up slightly to 7ft from the ESE, short period of 8 seconds, energy 899 – a bit weak and short period, so the shape might be a bit fat and crumbly. Still clean though.
Now here’s the thing – from Saturday the 22nd through to the end of the month, the surf quality takes a real dive. The guidance is callin’ it poor conditions. Saturday and Sunday the 23rd have height around 4ft to 6ft, but the energy is weak and the wind stays up. The swell is pretty gutless. This is a real lull. Most of the days between the 22nd and the 31st have swell under 3ft or just scrapin’ past it, with weak energy readings (often below 500, and down to 94 or 95). The wind is still blowin’, but the surf just ain’t there. That’s a solid gap of over a week with nothin’ worth gettin’ excited about.
But then, just when you think it’s done, Tuesday the 25th shows a bit of a pulse. We get a 5ft swell from the SSW, but here’s the kicker – the period jumps to 15 seconds. That’s long-period groundswell, energy at 1104. This is where the quality swings back. The wind is a moderate cross-off breeze from the ESE at 12 mph, so it’s gonna be clean. The swell direction is SSW, which is right in the optimum for Dumbea Rights. This is the standout window. The combination of the long period, clean wind, and right direction makes this the best bet in the entire forecast. The swell size is still under 6ft, so it’s not too heavy, but that long period will give it good shape and push. You want to be in the water on the mornin’ of Tuesday the 25th.
Wednesday the 26th is also interesting but a bit different. The wind flips to a light offshore from the WSW at 3 mph in the mornin’, with a 4ft SSW swell, period 15 seconds. The energy is moderate at 784. That light offshore wind is magic for a reef break like this – it’ll be glassy and clean. This is a serious contender too, but the swell is smaller than Tuesday. Thursday the 27th also has small, clean 3ft swell with light offshore winds. Friday the 28th onward, the swell drops off again and the wind picks up, so that’s the end of the good run.
So, the standout is hands-down Tuesday the 25th – that long-period SSW groundswell with clean cross-off wind, at a break that’s perfectly aligned for it. That’s your session. Wednesday the 26th is a very close second if you prefer smaller, glassy conditions with that light offshore breath.
Overall, this region has some classic ups and downs. There’s a long flat and windy spell mid-period, but the two days at the end of the first week into the second week bring the goods. Keep an eye on the forecast for that window – it’s the one.

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 Rights 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.
