The Lowdown
Alright, I'm looking at the charts for the next couple of weeks, and it's gonna be a proper mixed bag. We've got some solid swell windows, but a whole lot of wind and rain to sit through first. Let's break it down.
Right off the bat, we're looking at Dumps (Brandon Bay). There's some small, waist-high swell around on Tuesday the 25th of August, but honestly, the conditions are just ordinary. You've got a light offshore breeze, but the energy is weak (171), and the waves are nothing to write home about. Wednesday and Thursday are tiny, and by Friday the wind swings onshore, making a mess of things. Honestly, the first week is a struggle. From Friday the 29th all the way through to the 4th of September, it's nearly all onshore wind and stormy junk. That swell ramps up big time – we're talking 10ft on Monday the 31st – but with a fresh onshore wind, it's just a washing machine. The water temp is about where you'd expect for this time of year.
The real standout window, the one you've been waiting for, finally shows up on Saturday the 5th of September. That afternoon, Dumps lights up. We've got a solid 8ft swell rolling in from the WNW with a nice 11-second period. The combined energy is pumping (1681), but the real kicker is the wind. It's a gentle offshore breeze from the ENE. That's going to groom that swell into some proper, clean, pushing lines. This is the one you circle on the calendar. It's a bit solid, so maybe one for the experienced folks, but the quality will be there. The swell direction is ideal for the break.
Before that, on the Friday afternoon the 4th, there's a 10ft WNW swell with an offshore breeze, but it's still a bit raw, and the tide might be playing games. It's worth a look, but the Saturday session is the clear winner. A word of warning though – this break is listed as fairly consistent, so expect a few others to have the same idea. Get amongst it.
The following week drops off again pretty quick. By Sunday the 6th the wind is back onshore, and while we get a flash of long-period groundswell on the 8th and 9th – with 14 and 15 second intervals – the winds are just a bit off, keeping it from being epic.
So, bottom line: it’s a slow start, a proper dump of rain and wind in the middle, but if you can hold out for that Saturday the 5th of September afternoon session at Dumps, the wait will be worth it.
