The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Right, so for this stretch, we’re talking Dumbea Rights. It’s a consistent reef break, exposed to the swell, but the first week is a bit of a write-off for decent waves. The setup is there, but the wind is just too strong most days, and the size is either too big with messy conditions, or it drops off. The real standout, the one to circle on your calendar, is the morning of Wednesday, August 26th. That’s where it all comes together.
Let’s walk through it. From Tuesday the 18th, we’ve got a big 10ft swell from the SSE, but with a strong 25 mph cross-off wind, it’s just not going to be clean. The energy is massive (3356), but it’s too blown out. That pattern holds through the rest of the week; solid swell but the wind is always too fresh, keeping the quality marginal. By the weekend, the swell drops below 7ft and the wind is still annoying, so we’re looking at a gap of poor to flat conditions from Saturday the 22nd right through to Monday the 24th.
Then things shift. The standout comes on Wednesday, August 26th, early. We’ve got a 5ft swell from the SSW, and here’s the kicker: the period is a very long 16 seconds. That’s proper groundswell energy (1246), and for a reef break like Dumbea Rights, that’s the sweet spot. The wind is a moderate 12 mph from the ESE, which is a clean cross-off. The water temp is 73°, which is pretty much spot on for this time of year, nothing unusual there. This is the session to aim for. Thursday the 27th morning also looks promising with lighter winds and a clean 5ft SSW swell.
Looking into the first week of September, there’s a bit of a last hurrah on Monday, August 31st morning. It’s small at 3ft, but the wind goes glassy. That’s a rarity, and if you’re after some clean, small waves on a reef, that’s your window. After that, the wind swings onshore and it gets ugly again.
So, bottom line: the best on offer is the morning of Wednesday, August 26th at Dumbea Rights. Clean, long-period groundswell, manageable wind. The morning of Monday, August 31st is a backup for a glassy, small wave session. The rest of the time, you’re fighting the wind.
Rusty.
