The Lowdown
Alright folks, it’s Rusty here. Gonna be honest with you, looking at the next couple of weeks at Dumps (Brandon Bay), it’s a real mixed bag. We’re in for a dry spell before anything gets going, and then when it does show up, it might be a bit too much of a good thing.
Right now, the water’s sitting at 65°, which is a solid 4° warmer than usual for this time of year. That’s a nice surprise, but don’t get too excited just yet.
Straight off the bat, from Friday the 14th right through to the end of the 23rd, there’s pretty much nothing worth paddling out for. We’re talking a solid week and a half of flat, choppy, and messy conditions. The wind is either cross or cross-onshore, and the swell is weak—barely cracking 100 in the combined energy department. It’s a real bummer.
The first real flicker of hope comes on Tuesday the 25th. The morning shows a clean 3ft swell from the WNW with a 10-second period, and the wind is a clean cross-offshore from the NNE. The combined energy is a modest 160, so it’s not going to be a world-beater, but it’s the first clean conditions we’ve seen in a while. The afternoon turns a bit sloppy with a cross-shore wind, but the morning might be a sneaky window.
Now, keep your eyes peeled for Thursday the 27th. The morning session is looking like the pick of the bunch. We’ve got a 4ft swell from the WNW with a solid 11-second period, giving it a bit of grunt. The combined energy jumps to 305, and with that light NNE breeze at just 3 mph, it’s going to be glassy clean. That’s a proper window for a session.
But here’s the kicker. The end of the month is looking absolutely monstrous. From Friday the 28th through the 29th, a huge groundswell is forecast. We’re talking 20ft on Friday morning from the west with a 14-second period, and the combined energy is a staggering 14,432. That’s not just big; that’s dangerous. It’s going to be way too big for anyone but the most experienced big-wave chargers. The wind is offshore, but the size is the story here. Even the 18ft stuff on Friday afternoon and the 15ft on Saturday are going to be a full-on ledge show. The quality is there, but it’s a major step up in size.
So, to wrap it up: forget the first week and a half. The 27th is your best bet for a clean, fun, manageable wave. The end of the month is a true stand-out for the big-wave crew, but a pass for everyone else.
Rusty.
