The Lowdown
Alright folks, Rusty here. Let’s talk about what’s happening at Dumps (Brandon Bay). Don’t bother flipping the chart; the whole story is right in front of us for the next couple of weeks.
The headline is: a lot of waiting. The first few days are frustrating. The real reward is buried deep in the forecast, and it’s the morning of the 5th of September that’s the standout.
The Long Wait (Now through early September)
From Thursday the 27th of August, you can paddle out, but it’s not calling my name. The swell is small, about 3ft from the WNW, with a so-so 9-second period. The combined energy is weak (121). The wind is cross-off in the morning, so it’ll be clean, but it’s thin. The water sits near 63°F, feeling a touch warmer than the norm.
Then from the 28th of August right through to the 3rd of September, it’s a rough stretch. The surf is poor. We get a few pulses to maybe 5ft–6ft, but every time, the wind slams onshore or cross-onshore, turning it into a choppy, blown-out mess. That’s just time you won’t get back.
The Big, Messy Pulse (4th September)
Friday the 4th brings some serious muscle. We’re talking a massive 13ft groundswell from the WNW, with a long 12-second period. The energy is through the roof (4366 in the afternoon). This is a ton of water. But the wind is cross-on and choppy. At this size, with these winds, it’s a beast for experts only—and honestly, it looks better for kites than a surfboard.
The One to Chase (5th September)
Now, Saturday the 5th of September? That’s the golden window. The swell backs down to a much friendlier 7–8ft from the WNW, still with a 10-second period and strong energy (1104). The critical difference is the wind: a light 6 mph cross-off from the SSE. Glassy. Clean. The report calls for “very good surf conditions.” This is the call. It will be crowded, so be ready to share, but that morning session will be the best of the whole 16-day stretch.
The Slow Fade (6th through 11th September)
After that peak, the quality drops off fast. The 6th gets ravaged by strong winds. The days following see either strong onshores or tiny, clean but insignificant waves. By the 10th and 11th, we’re down to ankle-snappers around 2ft with no energy.
So here’s the plan: write off the first week. Friday the 4th is for the kamikaze crew only. The session you want is early on Saturday, 5th September. That’s the one.
