The Lowdown
Right then, let's have a look at what's on the table. The long-range picture for Dumps (Brandon Bay) is a bit of a mixed bag, with some real gems hidden in there if you're patient. The water's running a touch warmer than normal at 62°, so you won't need the thickest rubber just yet.
Kicking things off, there’s a bit of a lull. We've got some solid energy showing around the 8th of September – we're talking a big 10ft NW swell with a combined energy of 2051, but that wind is a nasty cross-on at 22 mph, so it's going to be a messy, lumpy day out there. Not worth the paddle.
Things stay pretty average for a while, with a lot of cross-on wind and choppy conditions through the 12th. Saturday the 14th sees a drop-off in size, and it's still not great.
Now, Sunday morning on the 15th? That’s the first real standout. We’ve got a 5ft NW swell, but more importantly, a light SSE breeze is blowing cross-offshore. That’s the key. It’s described as clean, and you’ll get some proper, well-shaped waves without the chop. The combined energy is a solid 737 – decent power. This session is the one to pencil in.
The following week has a few iffy days, but the big one to circle is Friday, the 20th of September. Dumps is going to be absolutely pumping with another 10ft WNW swell, period around 11 seconds, and a combined energy of 2122. That's some serious water moving around. Winds are light and cross with a gentle breeze, so while it might have a slight cross-chop, the sheer size and groundswell period will make for some heavy, powerful sets. Be warned, at 10ft this is expert territory, especially with that long period hitting a beach setup. But for the crew who can handle it, it’ll be incredible.
Then, Monday the 23rd of September morning is another beauty to finish the run. Swell drops to 4ft from the W, but the wind goes completely glassy. Zero wind, combined energy of 648, and a nice 11-second period. It won't be big, but it will be perfect. Clean, lined-up waves with no wind to mess them up. Ideal for a long, quiet session.
So, if you're picking your spots, hit Sunday the 15th morning for clean power, and brace yourself for the big stuff on Friday the 20th. Finish it off with a glassy morning on Monday the 23rd.
