The Lowdown
Right, surf’s up? Well, not really. The next 16 days at Dumps (Brandon Bay) are a real mixed bag of almost nothing and one very brief window of decent surf. The water’s currently sitting at 64°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus for when you finally get in.
We’re kicking off Monday afternoon, August 31st, with a weak 4ft W swell and a 10-second period. The energy is only moderate (362), and a cross-on wind from the WSW is making it messy. The next few days are much the same story – small, choppy, and not worth your time. We get a bump in size on Thursday, September 3rd, with a 5ft W swell and 9-second period, but the wind is still cross-on, so it’s a frustrating one.
Then, hold onto your board shorts. Friday, September 4th, sees a jump in size, but it’s all onshore. The real action is on Saturday morning, September 5th. That’s our standout. We’ve got a 8ft NW swell (11-second period) with a clean, cross-off SE wind. The energy is strong (1211), and it’s a proper groundswell. This is for the confident intermediate and above, as it’s a solid 8ft and the long period (11s) will have some punch. It’s a promising window, but it’s short-lived. By Saturday afternoon, the wind’s gone cross, and the swell’s dropping fast.
After that, it’s a long, drawn-out fade. Sunday the 6th drops to 3ft with a weak energy (141), and the forecast is full of small, choppy, and onshore conditions for over a week. There’s a tiny flicker of hope on Saturday, September 12th, with a clean 3ft NW swell, but it’s barely surfable. The last week of the forecast is a real energy desert, with tiny swells and strong onshore winds. Good news for kite surfers perhaps, not so much for us.
