The Lowdown
G’day, Rusty here. Let’s chat about Dumps (Brandon Bay) and what’s on the table for the next couple of weeks.
First few days are a bit of a write-off. Thursday afternoon (27 August) has a tiny 3ft from the WNW with a light cross-off, but the energy is a measly 96 – barely a ripple. Water’s a touch warmer than usual, 64°, but that’s about all that’s worth mentioning. From Friday (28 August) through Thursday (3 September), it’s mostly onshore or messy side-winds, with the swell trying to push through but getting chewed up. The biggest sets in this stretch – like 7ft on Tuesday (1 September) and 6ft on Thursday (3 September) – are blown out by strong winds. Energy jumps to 541 and 468, but it’s choppy and lumpy. Not worth the paddle.
Now, here’s the real deal. There’s a gap of poor days, but the standout is Saturday, 5 September afternoon. Clean 7ft from the WNW, period 10 seconds, energy at 928, and the wind’s a light NNE at 9 mph, cross-off – glassy as it gets for Dumps. That’s intermediate-friendly, but big enough (over 7ft) that beginners might want to sit this one out. Expect a bit of a crowd, but not stuffed, and the waves will be clean and punchy.
Monday, 7 September morning is also a good one: 7ft from the W, 10-second period, energy 982, with a light SSE cross-off at 6 mph. Clean again, a bit bigger, solid for experts. Tuesday, 8 September morning has 6ft from the W with a longer 12-second period (energy 848) and light offshore ESE wind – glassy. Because it’s a longer period, the sets might wall up a bit straight at the beach break, but the shape and push will be there.
After that, it’s back to cross-shore winds and smaller surf from 9 September onward. Not much to get excited about.
If you’re picking a session, Saturday 5 September afternoon is the one. Monday and Tuesday mornings are decent backup plans. The rest? Better off with a coffee on the beach.
Rusty.
