The Lowdown
Alright, this is Rusty, giving you the rundown on Dumps down here at Brandon Bay.
Got to be honest with you, for a spot that can fire, the first week or so is pretty grim. We’re looking at a solid six-day stretch of blown-out junk before anything becomes worth paddling for.
Your first chance to gets some waves is on Saturday the 5th of September. We’ve got a messy leftover swell around 6ft from the NW early, dropping off in the afternoon. The energy is moderate, but it's lumpy with a cross-shore wind. It's marginal – you might snag a couple, but don't expect much.
Things stay rough through the weekend and into the next week. We get a massive pulse on Monday the 8th of September, with a 13ft swell from the W and a period of 10 seconds. That’s a ton of water moving around. The combined swell energy is very strong, but the wind is howling from the SSW at 18 mph, ripping it to shreds. That’s a washing machine, far more interesting for the kite surfers than anyone on a paddleboard. That size is strictly for experts, and even then, forget it with that wind.
After that big pulse, we get a few more days of lumpy, bumpy conditions, but then things turn around. The true highlight is Monday the 14th of September. We’ve got a gorgeous groundswell from the W at 6ft, with a long period of 12 seconds. The energy is solid, and with a light, glassy offshore breeze from the SE in the morning, Dumps is going to be clean and peeling. The only thing to note is a long-period W swell can run a bit fast at a beach break, but with clean conditions, this is easily the top pick of the whole forecast.
Following that, the 16th looks decent too, but smaller. Wednesday the 16th of September has a clean 3ft swell from the W (11-second period) with a light cross-offshore breeze. It should be a fun, clean day for the longboards.
So, bottom line: sit through the rough stuff for the first week. Your target is that Monday the 14th – that's the one to circle on your calendar.
Rusty.
