The Lowdown
G’day, I’m Rusty. Alright, let’s have a look at what’s coming up for Whangamoa over the next couple of weeks.
To be straight with you, it’s a pretty quiet stretch. There are long gaps with hardly anything worth paddling out for. The first week is especially flat and ordinary, with most days offering nothing more than a ripple. The water temp here is sitting about average for this time of year, nothing unusual.
The only real window where you might score a wave kicks off on Sunday the 20th of September. That afternoon, a 1ft swell from the NW with a period of 16 seconds, a proper groundswell, starts rolling in. The combined swell energy hits 121 – moderate – and we get clean conditions with a gentle offshore breeze from the SE, which is a big tick for quality. Whangamoa is an exposed sandbar that’s inconsistent and rarely breaks, but when it lines up with a NW swell like this, it can offer a wave. That long period will suit the setup, so it might shape up better than the size suggests. Keep in mind though, the break is inconsistent so don’t bank on perfection.
After that, there’s another marginal moment on Monday the 21st of September morning, with a small 1ft NW swell and glassy conditions from the WNW, but it’s only showing poor conditions on the scorecard. Monday afternoon has 1ft of NW swell with a 14-second period, but the wind swings onshore from the N – not ideal.
Looking further ahead to Saturday the 26th of September afternoon, there’s a 1ft NW swell with a very long 20-second period, bumping the combined energy up to 106, moderate. But the wind is onshore from the NNW, and it’s still a marginal call. That’s over a week away, so treat it cautiously.
Honestly, if you’re keen for a surf, best to pencil in Sunday the 20th of September afternoon as the standout – it’s the cleanest and most promising. Otherwise, it’s a lot of waiting. The setup here, with this small swell and often poor conditions, might be more interesting for a kite surfer on the bigger, messier days.
Rusty.

Information about the Whangamoa Surf forecast
The above surf forecast table for Whangamoa provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Whangamoa can be found by selecting the local surf guide option on the grey menu. Our Whangamoa surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Whangamoa) 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 Whangamoa 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
