The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Dumps (Brandon Bay). This is going to be a long, frustrating wait for anything decent, so don’t get your hopes up too early.
The next week and a half is a real write-off. We've got a solid gap of about eight days from now through most of the month with no real surf to get excited about. The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, but that’s about the only thing going for us.
Tuesday 11th to Wednesday 21st August: This is a tough stretch. The waves are small and messy, with a lot of cross-shore and cross-on winds. The swell energy is weak, mostly in the low to mid hundreds (54 to 234), which just isn't enough to push any real shape. The waves are bumpy and choppy. It’s not worth paddling out.
Thursday 22nd August: There’s a slight uptick in size, with the swell picking up to 8ft to 8ft from the WNW, but the wind is still a problem. The morning is cross-on and the afternoon is a light cross-shore, which is better but still not clean. The energy is getting into the four-digit range (875 to 1053), but the conditions are described as poor, so it’s a pass.
The Standout – Sunday 23rd August Morning: This is the one to circle on the calendar. The swell is a solid 8ft from the NW, with a period of 10 seconds, giving it decent energy (1306). But the real magic is the wind – it’s glassy. That’s right, glassy. This is a true window of clean, lined-up surf. The waves might be a bit much for beginners at this size, but for intermediate and up, it’s likely the best we’ll see all forecast. It’s a rare moment of quality in a long, bleak outlook.
Late August: After that Sunday, it's back to the struggle. Monday 25th onwards sees strong winds (25 mph) and lumpy, onshore conditions, with the swell dropping back to 4ft to 6ft. The last few days of the forecast are just a howling mess with rain showers, so don't plan on it.
So, to sum it up: the next 16 days are mostly a dud, but if you can get out on the morning of Sunday 23rd August, you might just score the best session of the month. Keep your eyes on that one.
Rusty.
