The Lowdown

Alright folks, Rusty here. Let me level with you – if you've got your heart set on a proper surf around here over the next couple of weeks, you're gonna be fighting a losing battle. I've had a good look at what Whangamoa's got on offer, and it's a grim stretch. This is a sandbar setup, exposed to the northwest, and it's an inconsistent spot at the best of times. Right now, it's not even delivering that.

From Wednesday September 9th right through to the middle of the month, we're looking at tiny, gutless waves with poor surf conditions. Wednesday morning shows a tiny 1 ft from the northwest at a short 8 seconds – combined energy only 17 – and while the wind's glassy, it's just not enough to get excited about. That theme continues for days: flat spells, weak little 1.0 ft to 2 ft pulses, mostly cross or onshore breezes. Nothing worth paddling out for. There's a patch of total flatness from Thursday 10th through to Tuesday 15th where the energy drops to zero for long stretches.

We finally see a bit of a pulse around Wednesday 16th – 4 ft from the NNW at 8 seconds, combined energy 205 – but it's blowing moderate cross-shore and the conditions are labelled poor. Thursday 17th brings a longer-period 14-second groundswell, but with fresh cross-onshore winds up to 19 mph, it's messy and lumpy. Then Friday 18th morning has a clean bit of cross-offshore wind but only 1 ft – not worth it. The afternoon brings a 2 ft long-period 17-second swell (energy 309) but again cross-shore chop spoils it.

The real kicker comes on Saturday 19th and Sunday 20th – we've got serious size: 10 ft to 12 ft from the northwest, energy readings pushing into the thousands (1032 and 1829). But the wind is howling cross-onshore at 25–28 mph. That's not surfable for paddle surfing – you'd need a kite to have fun out there. Even then, it's messy. The following Monday 21st morning offers the best chance you'll see all forecast: 5 ft from the NNW at 10 seconds, energy 509, with a gentle cross-onshore breeze. The score is only a 2 out of 10 – marginal at best, and tide could mess it up. After that, it fades again into tiny slop and flatness through to the end of the period.

So to be straight with you: there are no good surf options in this 16‑day window. Whangamoa is an inconsistent break, and this run of poor conditions is pretty typical for the area when the swell windows don't align. The only faint glimmer is that Monday 21st morning – if you're desperate and the tide lines up, you might find a few weak, choppy rides. But don't get your hopes up. Forecasts can change, but right now I'd be leaving the boards at home.

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.
