The Lowdown
Alright, let's be honest, the next couple of weeks are looking pretty average for Dumps (Brandon Bay). The main issue is the wind. For most of the period, we’re dealing with onshore or cross-onshore breezes that are just ruining the shape. There’s swell around, but it’s a mess. We’re in for a long wait for anything clean.
Let’s get into it. The first real possibility doesn't show up until Thursday the 17th of September – that's over a week away. On Thursday morning, we’ve got a tiny 3ft groundswell from the west, but the wind drops right out to glassy conditions. The energy is weak though, with a combined swell energy of only 232. It’s a bit of a teaser.
Then on Friday the 18th of September, the swell picks up to a much more interesting 8ft from the west-northwest (energy up to 1176), with a long 11-second period. But the wind is from the south-southwest, so you’re still looking at lumpy, cross-onshore conditions. It’s a big, powerful swell with a long period, so it’ll have plenty of push, but it’ll be breaking a bit straight across the beach – best for the more experienced crew. It’s frustrating because the raw power is there, but the wind is a spoiler.
Now, the standout. Saturday the 19th of September looks like the pick of the bunch. The morning session should be firing. We’ve got a solid 7ft swell from the west-northwest with an 11-second period (energy at 1080), and most importantly, light offshore winds from the southeast. That means proper clean faces and good shape. The water temp is about average for this time of year. Just be warned, crowds are possible here. This is the one morning to circle on your calendar – it’s the only time the whole setup comes together nicely.
After that, the Sunday and Monday see the wind and swell get messy again, with a 10ft and 8ft swell on Monday the 21st being blown to bits by a strong onshore breeze. That’s big, powerful swell (energy hitting 4346), but only for the hardcore in a jet ski, honestly. The rest of the window fades away into choppy, junk conditions.
So to sum it up: there’s a long, dry gap until the 17th of September. Don’t bother before that. The one morning to get excited about is Saturday the 19th of September. That’s your window. Everything else is a write-off.
