The Lowdown
Alright, Rusty here. Let’s cut to the chase – the next 16 days at Haumoana River Mouth are a total bust. There’s no surf worth paddling out for. The swell is flat, the energy is pathetic, and we’re looking at a long, frustrating stretch of nothing.
The first few days are a wash. Friday morning (September 4th) has a 0.3ft NE swell with a 10-second period, and a crosswind from the NNW at 12 mph. The combined energy is a measly 9 – it’s barely a ripple. Saturday afternoon (September 5th) goes glassy with a 0.3ft easterly, but it’s still flat.
We get a tiny flicker of hope on Monday morning (September 7th) – 3ft from the NE with a 5-second period, and a clean offshore breeze from the SW at 6 mph. The energy climbs to 48, but it’s weak and the waves will be short and crumbly. It’s surfable, but it’s poor. Nothing else in that first week has any real juice.
The second week is even worse. Tuesday morning (September 8th) has a 4ft SE swell with a 9-second period, but the wind is a messy cross-offshore at 16 mph, and the energy is 179. That’s moderate, but it’s not clean. After that, it’s all downhill. Wednesday morning (September 9th) is glassy with a 2ft SE swell, but the energy is only 55, and it’s gutless.
From September 10th onward, it’s a total desert. Swell heights barely reach 1ft, the energy drops into single digits, and the wind is either onshore or cross-shore. There’s a massive gap from the 11th all the way through to the 16th, with only a few 0.3ft pulses. The 17th and 18th show a little more energy (36 and 34) from a long-period SE swell (15-16 seconds), but it’s only 0.7ft – that’s not breaking anywhere.
The only session that’s even worth mentioning is the Monday morning (September 7th) window. The offshore wind is clean, but the swell is too small and short-period to do anything. This is a dry spell, plain and simple. For a river bar, these long, flat runs are just part of the deal. Don’t hold your breath – the outlook is bleak, and it’s going to be a while before we see any real waves. Stay patient.
Rusty.
