The Lowdown
Alright, Rusty here again. Let’s cut through the noise on what’s coming up at Haumoana River Mouth. It’s a river bar setup, exposed to the swell, and it really wants a NE direction to get going.
I’ll be honest with you – this 16-day stretch is a total flat spell. It’s one of those times when the river mouth just shuts down. The water temp is a bit colder than usual for the season, sitting around 54°F, so you’ll want a thick suit.
The first sign of anything even worth mentioning doesn’t arrive until Tuesday morning, September 15th. It’s glassy, but the swell is a tiny 1ft from the SE with a short period of 10 seconds. The combined wave energy is weak (43), and it’s called very ordinary. Not worth the drive.
Thursday morning, September 17th, is another glassy morning, but still that weak 1ft ESE swell with a bit better 11-second period. Still very ordinary energy (46). You’re not missing a thing.
The only session that gets a pulse is Friday, September 18th. We finally see a little bump in size. Both the morning and afternoon offer a 2ft ESE swell (13-second period in the morning, 12 in the afternoon). The energy jumps to moderate levels (161 and 141). Morning is glassy, afternoon is clean with a cross-off breeze. If you have to paddle out, that Friday morning window is your best bet – but keep your expectations low.
From the 19th onward, it’s mostly onshore winds, tiny swell, or both. Tuesday the 22nd sees a 5ft SE swell with a strong breeze, but it’s still rated as poor surf, so that’s just messy and blown out. The energy spikes to 375 that afternoon, but with a strong cross-off wind, it looks way more interesting for kite surfing than paddle surfing.
The final week is completely dead. The last few days from the 25th to the 28th show nothing but tiny 0.7ft swell with very long periods (11-12 seconds). That long period stuff at a river bar is just a fat, straight wall – no shape at all.
Bottom line: there’s nothing worth chasing in this 16-day window. If you’re desperate for a glassy float, try Friday morning the 18th. Otherwise, leave the board in the car.
Rusty.
