The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Dumps (Brandon Bay).
Honestly, the next week and a half is a bit of a write-off. We’ve got a long, frustrating gap with basically no good surf on offer. The first sign of anything worthwhile doesn’t show up until Tuesday the 15th of September. Before that, it’s a whole lot of chop, cross-shore wind, and blown-out conditions. The water temp is about average for this time of year, so no surprises there.
The standout window is Tuesday the 15th of September. That morning, we’re looking at a clean 4ft swell from the west with a long 11-second period, giving some decent energy (334). The wind is light and coming from the southeast, which is cross-offshore, so the face will be clean. This is the best bet in the whole 16-day run. Given the long period, this groundswell will have a bit of punch and better shape, but it’s a fairly exposed spot, so it should handle it fine. It’s promising, but this is a long-range call, so keep an eye on it.
Before that, the only other flicker of life is on Monday the 14th of September. The morning has a tiny 2ft west swell with a long 11-second period, but the energy is weak (86). It’s clean with a light cross-offshore breeze, but it’s really only for the patient loggers. The afternoon sees a touch more energy (132) and a light offshore wind from the east, but the swell is still only 2ft.
Everything else is a mess. That big pulse of swell on Friday the 4th of September hits 15ft, but it’s wrapped in strong onshore wind, making it dangerous and unsurfable. The days after that are just messy and lumpy. The second week, from the 10th to the 13th, the swell drops right off and the wind is mostly cross or cross-offshore, but there’s simply no energy to work with.
So, to sum it up: hold tight for that Tuesday the 15th of September morning. It’s the only true standout in a very quiet period.
Stay safe, and keep your eye on the horizon.
Rusty.
