The Lowdown
Alright, Rusty here. Let’s break down what’s happening at Dumps (Brandon Bay).
First thing you need to know: you’re looking at a long stretch of junk. From now until the 4th of September, it’s mostly cross-on wind and chop. The wave energy is moderate at best (549) on Monday morning, but the conditions are so poor you’d be better off staying on the beach. This setup looks way more interesting for a kite than a paddle board.
The one day that stands out is Saturday the 5th of September. That morning is the real deal. You’ve got a clean 8ft swell out of the WNW with an 11-second period. The wind is a light breeze from the SSE, blowing cross-offshore, making for some clean faces. Water temp is a touch warmer than normal at 64°. The energy is strong at (1148). That’s the window to be in the water.
It gets messy again that same afternoon as the wind swings around, and the rest of the first week is a write-off with choppy, onshore slop.
Further out, Friday the 11th of September morning has a light offshore wind from the ESE, but the swell is only a weak 4ft from the NW. It’s surfable, but barely. The energy is low at (238).
After that, the second week turns dangerous. By the 14th and 15th, we’re seeing 10ft to 15ft of WNW swell (3018 to 6246 energy), but it’s all blown out by brutal, strong onshore winds. That’s for experts only, and even then, it’s going to be a washing machine.
So, the only standout is the morning of the 5th of September. Don’t sleep on it.
Rusty.
