The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for the next couple of weeks at Dumps (Brandon Bay). We’ve got a bit of a slow start, but there’s some proper promise lurking further out, so don’t write this one off just yet.
The first real surfable option doesn’t show up until the morning of Monday, the 10th of August. It’s small – just a 3ft NW swell pushing through with a weak energy reading of 167. It’s clean though, with a light offshore ESE breeze, so the conditions will be tidy even if the waves are very ordinary. The afternoon goes to crap with a cross-onshore wind, so that morning window is your only shot for a little one.
We then hit a long, frustrating stretch of poor conditions. From Monday afternoon right through the middle of the month, we’re looking at onshores, cross-shore chops, and very little in the way of quality. There’s a brief moment on the morning of Sunday, the 16th of August, with a tiny 2ft NNW swell and clean conditions with a NE cross-off breeze, but the energy is only 73 – that’s barely a ripple. It’s surfable, but you’ll be scratching for anything decent.
Now, the real standout, and the one to circle on your calendar, is the morning of Friday, the 21st of August. We’ve got a solid 6ft NW groundswell with a 9-second period and a combined energy of 500 – that’s moderate but packing a punch. The wind is light and offshore from the east, meaning it’ll be glassy. That is clean, proper surf for an intermediate surfer. For the experts, the morning of Thursday, the 20th of August also deserves a mention with a bigger 7ft WNW swell and an offshore NE breeze. The energy is 719, so it’s got grunt, but at 7ft it’s edging into big territory for most. If you’re confident, that Thursday morning is a ripper.
After that, things fade off quickly. The swell drops back under 3ft by the 22nd and 23rd, with the winds turning iffy again, so that Friday the 21st morning is the true peak of this forecast.
Water temps are sitting at 64°, which is a touch warmer than normal for this time of year, so the rubber might feel a bit more comfortable.
Keep your eyes on that Friday the 21st morning. It’s the one worth the wait.
Rusty.
