The Lowdown
G’day, I’m Rusty. Let’s break down what’s coming up at Dumps (Brandon Bay). This spot is fairly consistent and gets a good look at the swell, with the best direction from the northwest. Water temp is about 63°, which is just a touch warmer than normal for this time of year.
We’re starting with a blast. Friday the 4th has a huge 13ft swell from the WNW, 12-second period, and a massive 4626 energy reading, but the wind is hammering straight onshore at 22 mph from the west. It’s all chop and chaos. Not for a surfboard – kitesurfers might be the only ones having fun.
Saturday the 5th morning is the real standout. Swell comes down to 8ft from the WNW, still a solid 11-second period, and the wind swings light cross-off from the SSE at 6 mph. Clean. Energy is still pumping at 1192. That’s your session. The waves will have shape and power. It’s intermediate territory at that size, so if you’ve got the skills, get in. The afternoon fades into mediocrity.
Sunday the 6th through Monday the 14th is a long, rough stretch. There’s plenty of swell – some days pushing over 8ft with energy readings in the thousands – but the wind is almost always onshore and often strong. Tuesday the 8th sees a massive 15ft WNW swell at 12 seconds with 5457 energy, but with 22 mph westerly winds, it’s a blown-out mess. Hard no for most surfers.
Finally, Saturday the 12th afternoon offers a bit of relief. The swell is a friendly 6ft from the WNW, 10-second period, and the wind goes glassy. That’s a dream window. Clean, calm, and 548 energy still gives you plenty to work with. The morning of the 12th is also clean at 6ft, just a light cross-onshore.
Thursday the 17th is another bright spot. Morning brings a 5ft WNW swell with light cross-off winds, clean. Then the afternoon goes glassy with 5ft swell – another special session. Those longer period swells (15 seconds on the 14th) can be a bit tricky on beach breaks, but Dumps handles groundswell well as a point break.
By Friday the 18th and Saturday the 19th, it’s all falling apart. Saturday afternoon is down to 1.0ft and 61 energy with a light cross-onshore. That’s your lot.
Best on offer: Saturday the 5th morning for the size and clean conditions, and the glassy afternoons on the 12th and 17th for the silky, fun waves. Dumps can get crowded when it’s good, especially weekends. First week is the main event, second week is smaller but still worth a paddle.
Rusty.
