The Lowdown

Alright, grab your wettie, let’s have a look at what’s on offer at Whangamoa over the next couple of weeks. I’ll be straight with you – it’s a tough run for the most part. There’s a tiny window of hope early next week, but you’ve got to be patient.

Whangamoa is a sandbar set-up, so it’s never the most consistent spot, and this forecast proves it. For the first few days, it’s pretty much a write-off. Sunday the 6th is a complete no-go with strong onshore winds and messy, poor surf. Monday the 7th, things start to shift. The morning sees a light SSE offshore wind and a 3.6ft swell, but it’s still poor. By Monday afternoon, we get a tiny bit of life: a 2.9ft swell from the NNW with a 9-second period, and the wind is offshore. The combined energy is only moderate (127), and the waves are very ordinary, but at least the conditions are clean. It’s a one-star day.

Now, Tuesday the 8th of September is our standout. Tuesday morning, the wind drops to glassy – absolute magic. The swell is small, just 2.0ft from the NNW with an 8-second period, and the combined energy is weak (55). But with those glassy conditions, you’ll find some fun little waves if you’re on the right sandbar. It’s not a big day, but for the area, it’s the best we’ll see. The water temp anomaly is about average for this time of year, so don’t expect any surprises there.

After that, the window closes fast. Tuesday afternoon gets onshore again, and from Wednesday the 9th all the way through the rest of the forecast, it’s mostly poor surf with cross and onshore winds, and very little energy. There are gaps of several days – from Wednesday the 9th right through to the end – where the swell either disappears or the wind just ruins it. You’ll see a few days with 2.3ft or 3.6ft waves, but the wind is never right for Whangamoa. The 10th has a clean morning with a 3.6ft swell (79 combined energy), but it’s a cross-offshore wind, so it won’t be firing.

Long-range, around the 17th and 18th, there’s a little bump of 2.3ft to 3.6ft swell, but the period is short (6-8 seconds) and the wind is cross-shore or cross-offshore. Nothing worth getting excited about, and definitely not reliable.

Bottom line: If you’re keen, be on the water Tuesday morning, the 8th, for the cleanest conditions. After that, it’s a long wait. Don’t hold your breath.

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.
