The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s going on with Whangamoa. It’s a sandbar set-up that needs a good NW swell, and to be honest, the next couple of weeks are looking pretty grim. We’ve got a long dry spell on our hands before anything even remotely rideable shows up.
The water temp is sitting at 55°, which is bang on average for this time of year, so no surprises there.
From now until the morning of Saturday the 8th, it’s a total write-off. Tiny, short-period slop, onshore winds, or just flat – nothing doing. There’s a whole week of that to get through. The combined swell energy is barely registering, so don’t even bother.
Finally, on Saturday the 8th, we start to see a pulse. The morning brings a 4ft swell from the NNW with a period of 9 seconds. The combined energy is moderate. It’s cross-shore winds, so it’ll be a bit bumpy, but there’s something to push you around. The afternoon is similar, 4ft from the NNW, but period drops to 8 seconds and the wind goes cross-onshore, making it messier. It’s a marginal call, but it’s the first real chance.
Sunday the 9th morning is the pick of the early window. We’ve got a 4ft swell from the NNW, 8-second period, and the wind is a clean cross-offshore from the SSW. The energy is moderate. It’s not going to set the world on fire, but it’ll be the cleanest waves of the first week.
The following week is more of the same – small, weak, and mostly blown out. There’s a bit of a lift on the 16th. Sunday the 16th afternoon shows a 6ft swell from the N, 9-second period, and the energy is strong. The wind is cross-offshore, making it look clean. That’s a step up in size, but for a sandbar, that 6ft at that period might be a bit fat and tricky. Still, it’s the best size on offer.
The real standout, if you can wait, is Sunday the 16th afternoon. With 6ft of N swell and clean cross-offshore wind, it’s the best chance for a decent wave. The 4ft on Sunday the 9th morning is a solid second option for a clean session, but much smaller. Everything else is just a waiting game.
Stay patient, and don’t get too excited about the long-range stuff. Forecasts can change.
Rusty.

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

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.
