The Lowdown
G'day, Rusty here. We've had a rough run of it lately, but I gotta say, there's a light at the end of this tunnel. The next week and a half is mostly blown out or messy, but we've got a proper window of clean surf lined up for the tail end of the period that's worth getting excited about.
First up, Dumps (Brandon Bay) is the only game in town. It's a fairly consistent, intermediate-level spot that's fairly exposed to swells, and it likes that NW direction. The water temp is sitting about average for this time of year.
We start with a bit of a wait. Saturday the 12th throws up a decent sized 10ft west swell, but it's a cross-onshore mess with light rain. The wave energy is strong (1885), but the wind is just destroying it. Sunday and Monday stay small and cross/choppy, nothing to write home about. Tuesday the 15th through the 20th is a real tough stretch. We get waves, some of them solid, like that 12ft WNW groundswell on Thursday the 17th (energy reading a massive 4794) and again on Sunday the 20th (4981), but the winds are howling onshore from the WNW. It's lumpy, choppy, and honestly, with those strong winds and a beach setup, this is looking more interesting for kite surfing than paddle surfing right now.
Keep an eye on Monday the 21st. The swell drops a touch to 8ft from the NW, but the wind goes very light from the SW with just 3 mph. It's still cross-on, but with only small wind ripples, it might be the best of a bad bunch for a sneaky session. Not a standout though.
Now here's the payoff. For those of you who can wait, mark your calendars for Wednesday the 23rd of September. This is the one. We've got a 8ft NW groundswell with a long 14-second period. The wind flips to a light offshore breeze from the east. The conditions are described as "clean." This is excellent for experienced surfers—that size is punchy. That period is long, so it'll be better shaped at a spot like this, and it's long enough to make paddling out easier between sets. The wave energy is strong (2130). This is our standout. Yes, crowds are possible here sometimes, but on a Wednesday with clean 8ft waves, it'll be worth sharing. A close second is Thursday the 24th morning—still clean with a 7ft WNW swell and light offshore from the SSE.
Friday the 25th morning stays clean with a smaller 6ft swell, good for a more relaxed session if that big Wednesday is too much. After that, the wind swings back onshore and the forecast gets lumpy again, finishing with a massive 15ft on Sunday the 27th, but with howling rain and wind. So, the call is clear: suffer through the slop for the next week, and be ready for that beautiful, clean Wednesday.
Rusty.
