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.

Signing off,
Rusty

A general guide to surfing at Haumoana River Mouth can be found by selecting the local surf guide option on the grey menu.

If you surf the same spot (Haumoana River Mouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Haumoana River Mouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
