The Lowdown

G'day, Rusty here, checkin' in with the outlook for the Dumbea Left reef break. Let's get straight into it, cause it's a bit of a mixed bag ahead.

Alright, first up, the water temp is sittin' around 72°, which is pretty much spot on for this time of year, so nothin' weird there.

We're in for a long wait, mate. The first week and a half is pretty ordinary. Thursday the 10th through to the next Thursday are a write-off with no real surf to speak of. The wind is just howlin' from the southeast, cross-shore and cross-onshore, messin' up any chance of a clean wave. The swell energy is all over the place, but it's just not combin' with the right conditions to make it worth paddlin' out.

As we move into the second week, things start to get a bit more interesting, but it's still a game of patience. Saturday the 12th is the first time we see some real size, but it's a double-edged sword. The morning shows a massive 12 ft SSW swell with a 17-second period, and the combined energy is a whopping 7456. That's a serious amount of water movin', but the wind is a fresh cross-shore, so it's gonna be lumpy as hell. This is only for the experts, and even then, it's a bit of a beast. The afternoon cleans up a bit with a cross-offshore breeze, but it's still a heavy 10 ft.

The next few days, from the 13th to the 15th, we have some cleaner conditions with cross-off winds, but the swell is fluctuating between 7 ft and 10 ft. The energy is still strong, but the surf quality is only marginal. It's a bit of a tease, really.

Now, here's the standout. It's a bit of a way off, but mark Wednesday the 23rd in your calendar. The morning session is lookin' the goods. We've got a 8 ft SSW groundswell with a 15-second period, and the combined energy is a solid 2844. The real kicker? The wind is glassy, mate. Dead calm. That's a rare treat. For this break, a long-period swell from the SSW is what it's made for, but it's a reef break, so that long period will mean the waves will have plenty of power and shape. It's a lot of water, so this is for experienced surfers only, but it could be a unforgettable session.

After that, the 24th and 25th see the swell drop off, but we get some decent conditions. The 24th afternoon has a light offshore breeze from the NNE with a 4 ft SSW swell, which is a nice little window for a clean, cruisy session. The 25th afternoon has a bit more size at 6 ft from the SW, but it's a bit choppy with a cross-on breeze.

For the first week and a half, the wind is just too strong and the conditions are messy. The standout is the glassy morning on the 23rd of September. It's a long way off, so don't bank your life on it, but it's the one to keep an eye on.

Rusty, out.

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.
