The Lowdown
Hey folks, Rusty here.
Gotta be honest, the next couple of weeks are lookin’ bleak for a decent paddle. The swell is gonna show up, but the wind is gonna be a real bastard for most of it. We’re lookin’ at a long stretch of poor conditions from mid-August through the end of the month. Honestly, the first real glimmer of hope is a long way out. It’s a proper drought.
The only spot I’d even think about is Dumps (Brandon Bay). For the first real chance, you’re lookin’ at Tuesday afternoon, August 18th. The water out here is about 65°, which is a solid 4° warmer than usual for this time of year - that’s really standin’ out, feels like a warm bath out there.
That Tuesday afternoon is your best shot, and it’s still not clean. We got a 7ft swell from the WNW with a 9-second period. The combined energy is moderate at (722). The wind is honkin’ from the W at 9 mph, puttin’ it onshore. It’s gonna be a bit lumpy and tricky, but it’s the only thing worth a look in the near term. The forecast says it’s marginal ‘cause of questionable tides.
After that, it’s a total bust. From Wednesday the 19th all the way to the start of September, every readout is just “poor surf conditions.” We’re seein’ howlin’ winds – 18 to 25 mph and cross-shore to cross-on. The swell gets up there, like Thursday the 20th showin’ a 8ft NW swell with combined energy hittin’ (1447), but with 22 mph cross-shore winds, it’d be a total mess. Not worth paddlin’ out.
There’s a little flicker of somethin’ on Wednesday, September 2nd in the morning. We see a 7ft swell from the W with an 8-second period and light cross-shore winds at 6 mph. Still labelled as marginal, and it’s over a week and a half away, so take that as a long-shot hope.
So, bottom line? Don’t even bother for the rest of August. The only day that might give you a half-decent ride is Tuesday the 18th at Dumps, and even then, keep your expectations low. The rest is a write-off.
Rusty.
