The Lowdown
Alright, folks. Rusty here. Let’s break down the surf for Dumps (Brandon Bay) over the next couple of weeks.
First things first, you’re gonna be waiting a while. The forecast is looking pretty grim for the rest of this week and all weekend. Strong winds are going to mess things up, with onshore and cross-on conditions and some serious swell. We’re talking over 8ft from Monday the 7th, with a massive 2923 combined energy (moderate wave energy) by Tuesday the 8th, and a period of 12 seconds. That’s big, powerful, and ugly. Unless you’re a pro looking for a fight, it’s a no-go for paddle surfing. The setup looks more interesting for kite surfing honestly.
We finally get a little cleaner window on Thursday the 10th morning. The wind will be a light cross-off breeze from the SSE, and it’ll be clean. Swell is a modest 4ft from the WSW at 8 seconds, so a little short period, but it’s rideable. The water temperature is sitting at 63°F, which is a touch warmer than normal for this time of year. Not a standout, but a session.
The real standout comes on Saturday the 12th afternoon. The wind goes glassy, which is a major positive. Swell is 6ft from the WNW at 10 seconds, with a combined energy of 601 (moderate wave energy). This is going to be clean and fun. That’s your best bet for the first week.
After that, Sunday the 13th morning offers clean 3ft waves from the NW with a light cross-off breeze, but it’s small. The real promise is further out. On Wednesday the 16th morning, we get another clean run with a 6ft WNW swell at 11 seconds and a light cross-off SSE wind. That’s a good, solid groundswell, and the combined energy is 631 (moderate wave energy). This is the one to circle in the longer range. It’s a bit far out, so don’t plan your life around it, but it’s the most promising looking swell direction with the cleanest conditions on offer.
So, if you’re itching for a wave, wait for the glassy afternoon on Saturday the 12th, or even better, that Wednesday the 16th morning session. The rest of the time, it’s mostly a write-off with strong wind and lumpy conditions.
Rusty.
