The Lowdown
Rusty here, checking in from the banks. Let’s talk about Haumoana River Mouth.
Honestly, mate, the next couple of weeks are looking pretty grim. I'm scouring the charts and there's just nothing on the cards that's going to get the stoke levels up. We’ve got a long stretch ahead with no real swell to speak of. The water temp is sitting at 54°F, which is a bit colder than normal for this time of year—nothing too crazy, but you'll want the thick rubber.
The first hint of anything rideable pops up on Tuesday, September 8th, but even then it’s marginal. Tuesday morning sees a 5ft swell from the ESE with a period of 9 seconds, but it’s a cross-off wind from the SW at 12 mph and combined energy is only moderate (355). By the afternoon, the swell drops a touch to 5ft and the wind stays cross-off. Honestly, the call is "marginal," so expect bumpy, junky lines—not worth rushing out.
Wednesday, September 9th morning is the only time that looks remotely promising. The wind goes glassy with a light WSW breeze at 3 mph, which is a major positive. You’ll get clean faces on a 4ft ESE swell, but the period is only 8 seconds, so it’s not holding together well. Combined energy is at 170 (moderate). It’s surfable, but it’s very ordinary—small, short-period slop.
After that Wednesday, it’s all downhill. From Thursday the 10th right through to Tuesday the 22nd, it’s pretty much a wipeout. We’re talking tiny waves, mostly under 2ft, with periods all over the place and a lot of junk wind. There’s a brief flicker of a 14-second period swell on Friday the 11th, but it’s only 0.7ft high—less energy than my morning coffee. The wind is offshore from the WSW at 3 mph that afternoon, which would be a dream with real swell, but with nothing to work with, it’s just a flat, clean ocean.
This river bar is exposed to the NE, but the optimum direction is from the NE, and we just aren’t getting that love. It’s rated for advanced surfers, which is fair given the shifting banks and rip, but there’s no danger of any crowd out there—nobody’s paddling out on this stuff. To be honest, with these weak southerly windswells and the beach setup looking so poor, you’d probably have more fun strapping a kite on.
Stay patient. This blank run is just one of those times where the ocean is taking a break. Forecasts can change.
Rusty.
