The Lowdown
Alright folks, Rusty here. Gonna level with you straight up – looking at the next 16 days for Dumps (Brandon Bay), it’s a real mixed bag of frustration and promise. The water temp is sitting about average for the time of year, so nothing to write home about on that front. The first week is a write-off with a lot of wind and chop, but there’s a glimmer of something special trying to break through near the end of the second week.
For the first week, from the 28th of August right through to the 4th of September, it’s grim. We’ve got onshore winds, cross-onshore junk, and the swell is either too small or blown out. The combined energy is weak to moderate at best, sitting around 50 to 100 (moderate wave energy) early on, then jumping up to 651 (moderate wave energy) by the 31st, but it’s all messy. Don’t even bother paddling out. There’s a tiny window on the morning of the 2nd of September where the wind goes cross-off and the conditions are clean, but the swell is only 4ft from the WNW with a short 8-second period – surfable but very ordinary. The morning of the 3rd of September sees a 7ft WNW swell with a 10-second period, but a 30 km/h cross-shore wind makes it a lumpy, choppy mess.
Then things get real interesting. The morning of the 5th of September is the standout. The wind is light, glassy, and offshore from the west at just 5 km/h. The WNW swell is 8ft with a 11-second period, pushing 1613 (moderate wave energy) of combined energy. That’s groundswell, and for a fairly exposed spot like Dumps, that’s quality. The sets will have some punch, and the lack of wind will mean clean, peeling faces. This is the one to circle on your calendar. The 5th afternoon and the 6th morning are still okay, but the wind shifts and the size drops, so the 5th morning is the real window.
The 7th and 8th of September are small again, 4ft to 4ft, clean but weak. The 9th of September sees a 10ft WSW swell, but it’s accompanied by a 35-45 km/h cross-onshore wind, making it a total mess. The 10th of September is a straight-up gale warning – 15ft NW swell with 60-65 km/h onshore winds. That’s not for paddle surfing; that’s for kite surfers or the insane. The 11th and 12th of September drop back to small, 4ft and 2ft, with strong cross-onshore winds.
So, the best on offer is without a doubt the morning of the 5th of September. That’s a legit session. Get on it.
Rusty.
