The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cookin’ for Dumps (Brandon Bay). We’re starting off real quiet, but there’s a pulse later on, though it’s gonna be a battle with the wind.
The first few days are a bust. Wednesday the 26th and Thursday the 27th have tiny surf, with the swell energy barely a whisper (39 to 161). The wind’s cross-off, so it’s clean, but the waves are puny and weak. Friday the 28th and Saturday the 29th are even worse – onshore winds and poor, choppy junk. Don’t bother.
Sunday the 30th is a little ray of hope. The morning is dead glassy, calm winds, with a 3ft swell from the west, 9-second period. The combined energy is moderate (184). The waves are clean but ordinary – you might scratch a few, but it’s not a standout.
From Monday the 31st onward, the size jumps up – but so does the wind. We’re seeing swell heights between 4ft and 8ft, with moderate to strong wave energy (551 to 1165), but it’s all cross-on or onshore, making it choppy and messy. The real deal is Thursday the 3rd of September afternoon: 8ft from the west with a 10-second period, and the energy is strong (1165). The wind is cross-on, so it’s not perfect, but it’s the most powerful of the run. That’s expert stuff.
The best window is Saturday the 5th of September morning. The swell is 7ft from the WNW (10-second period), with a light cross breeze and a gentle cross-chop that keeps it ridable. The combined energy is strong (874), and it’s clean and workable. This is your pick of the fortnight – solid, punchy waves for strong intermediates and up, with a bit of crowd potential (crowds are “sometimes” here, so you might see a few others).
After that, it drops off. Sunday the 6th and Monday the 7th are messy, with strong winds and poor conditions. The 7th has a 8ft to 8ft swell from the NW, but with a strong onshore breeze, it’s a dangerous mess – only for the brave or the kiteboarders.
For the second week, the 8th to the 10th of September have some clean cross-off windows, but the energy is low (180 to 625) and the surf is small (4ft to 5ft). It’s not terrible, but it’s not a standout.
The water temperature is about average for the time of year, so no big surprises.
So, the standout is Saturday the 5th of September morning. Don’t get your hopes up for the rest – it’s a mixed bag of frustration and fleeting fun.
Rusty.
