The Lowdown
Alright, Rusty here. Let’s talk about the next stretch at the river mouth.
We start off small but clean on Thursday the 6th of August. Haumoana River Mouth has a 3ft SE swell running with a 10-second period, and the morning wind is blowing offshore from the WSW at 9 mph, leaving the surface glassy. The water temp is about average for the time of year. Combined swell energy is moderate at (198). It’s not pumping, but it’s a nice, clean little wave for the advanced crew who know the river bar. The afternoon bumps up to 4ft, still from the SE, with a light cross-offshore breeze keeping things tidy. This is the best early window – clean, rideable, and not a big crowd.
Friday the 7th keeps the small waves going in the morning – 3ft with an 11-second period – and the wind stays light and cross-offshore. Worth a look if you missed Thursday. Saturday and Sunday go flat and messy, with weak energy and poor conditions. Not worth paddling out.
There’s a lull through the middle of the week, then Thursday the 13th of August brings a 4ft NE swell, but the period is a short 6 seconds. It’s glassy in the morning, but that short-period stuff can be a bit crumbly on the river bar. Still, with the wind calm, it’s clean enough for the advanced surfer to have a session.
Now here’s the big one. Tuesday the 18th of August sees a solid 10ft swell from the ESE with an 11-second period, and a strong offshore wind from the SSW at 25 mph. The combined energy is huge at (2078) – that’s serious power. This is for experts only. The river mouth will be handling a lot of water, and the wind is clean, but the size is intimidating. Know what you’re doing.
Wednesday the 19th drops to 7ft and then 6ft, still with clean wind, but much more manageable for strong surfers. By Friday the 21st of August, we’ve got a 6ft E swell with a short 8-second period and light offshore wind, and the energy is still solid at (563). It’s a fun way to finish the run.
Best bets: the morning of Thursday the 6th for a clean, small session, and the morning of Tuesday the 18th for advanced surfers looking for a big, powerful river mouth wave. The gap from Sunday the 9th through Wednesday the 13th is a real dead stretch, but once it comes alive, there’s some real grunt in the water.
Stay sharp.
Rusty.
