The Lowdown
G'day, Rusty here. Look, I'll be straight with you – the next couple of weeks are looking pretty grim for Whangamoa. This is a sandbar setup that's exposed to the NW, and we're just not getting the right combo of swell and wind. We've got a long stretch coming up with next to nothing on offer.
The water temp is sitting at 55°, which is about average for this time of year, so nothing unusual there.
The first real chance of anything decent doesn't pop up until Sunday the 13th of September. Even then, it's a one-off. Sunday afternoon we get a bit of a pulse – 5ft swell from the NW with a short period of 6 seconds. The combined energy is moderate at best (239). But the wind is glassy, calm from the ENE, and that's a major positive. The waves will be clean and smooth. It's not big, but it'll be the cleanest surf we see in this whole period.
Then Monday the 14th of September morning, it gets bigger – 7ft from the NW, period of 7 seconds, and the energy is strong (452). Wind is glassy from the SW. The problem is, at over 7ft, this is really only for the experienced crew. It's going to be a powerful, clean wave, but too much for beginners. The swell direction is a solid NW, matching the optimum, and the cross-off wind will keep it tidy.
Other than that, it's a whole lot of nothing. There's a big gap from now right through until that Sunday the 13th. Most days we're looking at onshore or cross-onshore winds, small, weak swells, or just flat. The 11th of September Friday has some size – 8ft to 10ft from the NNW – and clean cross-off winds, but it's flagged as too big for the break, so I'd steer clear unless you're a charger on a big board.
Honestly, for the sandbar here, this run of poor conditions is pretty normal. When it's not working, it's not working. But keep an eye on the glassy window around the 13th and 14th – that's your best bet.
Stay salty.

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.
