The Lowdown
Right off the bat, I gotta be straight with you: the next week and a half at Dumps (Brandon Bay) is looking pretty grim. We’ve got a run of small, weak surf and messy winds that’s gonna stretch out for a while. The swell energy is just dribbling in—we’re talking values in the 50s and 100s (weak to moderate at best), which isn’t going to get anyone too excited. The water’s sitting at 64°, which is a touch warmer than usual for this time of year, so at least it won’t be freezing while you’re staring at the flatness.
The first few days are a write-off. Sunday the 9th has some chest-high swell but it’s cross-on and choppy, so forget it. Monday the 10th is smaller and clean, but it’s barely surfable—knee to waist high at best. The gap of poor conditions runs right through to about the 16th, with only tiny, weak pulses and cross-shore winds making things messy. There’s a clean morning on the 16th, but it’s ankle-biters with a 6-second period, so it’s not worth paddling out for.
We finally see a bit of life on the 18th, but it’s still poor. The swell bumps up to 5ft to 6ft, but the wind is cross-on and the energy is still moderate. It’s not going to be pretty. The 21st shows a little more promise with 5ft from the NW and a 10-second period, but the wind is still cross-on. It’s marginal, at best.
Now, here’s the light at the end of the tunnel, and it’s a good one. The 23rd of August is the standout. We’ve got a proper groundswell filling in—6ft from the WNW with an 11-second period. Sunday morning is glassy. That’s the one you want. It’s a bit big for beginners, but for the intermediate crew, that’s going to be clean and fun.
And don’t sleep on the 24th either. Monday morning sees the swell peak at 7ft from the WNW, with a 10-second period and energy going through the roof. The wind is offshore and light, so it’s going to be clean and lined up. This is expert territory at that size, but it’s the best the window has to offer. The afternoon backs off a bit and the wind swings cross-shore, so get on it early.
So yeah, the first week and a half is a bust. But that last weekend into Monday is worth waiting for. Mark your calendar for the 23rd and 24th. It’s a long way out, so don’t take it to the bank, but the signs are good. Keep an eye on it.
