The Lowdown
Right then, let's have a look at what's cookin' for Haumoana River Mouth over the next couple of weeks.
Honestly, it's a pretty flat and quiet picture for the most part. We've got a long stretch of not much happening from now through the end of August and into the first days of September. The combined swell energy is mostly sitting in the low double digits (16 to 40), which is basically nothing. You'd be hard-pressed to get a ride. That 26th of August through the 31st is a write-off for any proper paddling.
Now, we start to see a little pulse of life around the 2nd of September. On Wednesday morning the 2nd, we've got a bit of a pulse from the southeast. It's not huge, around 3ft, with a period of 9 seconds. The combined energy bumps up to a moderate 118, and we get a light offshore cross-off breeze from the WNW, so it's looking clean. It's still just ordinary, surfable waves, nothing to write home about, but it's the best on offer in this whole outlook.
Then again on the morning of Thursday the 3rd, there's a small southeast groundswell with a longer 14-second period pushing in. It's only 1ft, but that longer period gives it a bit of shape. The energy is at 111 (moderate), and with a light cross-off from the NW, it'll be clean. For a river mouth setup, that longer period swell can be a bit tricky – it might wrap in or just run a bit too straight – but it’s still the standout of the bunch.
Outside of those two mornings, it's all poor surf conditions, onshore crud, or flat spells. There's a day or two gap after that before things go quiet again. Don't expect any barrels or big walls; it's a survival mission for a few small, clean waves if you're keen.
