The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Brandon Bay. The long-range picture is a bit of a slow burn, but there’s a proper window of clean surf opening up if you’re patient. The first week is mostly a write-off with strong onshore winds and messy conditions, but we get a solid run of quality waves starting on the 12th.
The water temperature is sitting at 63°, which is a touch warmer than normal for this time of year at Dumps (Brandon Bay). It’s a nice little bonus for the skin.
The first few days are grim. Thursday and Friday the 3rd and 4th are blown out with strong onshore winds and a massive, unruly swell. The combined wave energy is huge (4742), but it’s all wind-slapped and ugly. Not worth a paddle. Saturday the 5th shows a glimmer – cross-off winds and a clean 7ft swell from the WNW, but the energy drops quick. You’ll get a few, but it’s not the standout.
The real action kicks off on Saturday the 12th of September. Morning brings a 12ft NW groundswell with a long period of 13 seconds. The combined energy is pumping (3853), and the wind is a gentle cross-off. This is a heavy, powerful swell. At 12ft, it’s expert territory only. The point break nature of Dumps will handle this long-period energy well, giving it shape and holding it together. The afternoon cleans up even more, with an 8ft WNW swell, still long-period (12 seconds), and glassy conditions. The combined energy is still strong (2116). This is the best on offer – a full day of proper, grinding groundswell with light winds. It’s a standout.
The next day, Sunday the 13th, the swell backs off, and the wind goes cross-on, so get it while you can on the Saturday.
Looking further out, Tuesday the 15th of September is another treat. The morning is glassy with a 6ft WNW swell and a 10-second period. The combined energy is moderate (610), and the conditions are described as glassy. This is a much more manageable size for intermediates, and the lack of wind will make it silky smooth. Crowds are possible at Dumps, so get there early. The afternoon holds the same glassy conditions.
The rest of the second week is a mix of smaller, cross-on swells and onshore winds, so nothing to get excited about. The 18th looks like it might try to pump again, but the wind is all wrong, ruining it.
Overall, the clear standout is Saturday the 12th of September for the experienced crew, with Tuesday the 15th being a solid call for the intermediates looking for clean, user-friendly waves.
Rusty.
