The Lowdown
G’day, Rusty here. Let’s be straight up – the next couple of weeks at Whangara are a bit of a mixed bag, with a lot of average-to-poor days to wade through before a couple of genuine standouts show at the end of the month. We’ve got a long stretch of nothing much worth paddling out for, then a clean little window that’s worth marking on the calendar.
The water temp at Whangara is sitting at 56°F right now, which is about 1°F cooler than average for this time of year – nothing unusual, just a touch of winter still hanging around.
We kick off on Wednesday 19 August and it’s plain ugly. A solid 16 ft southerly swell is hammering the coast, but with a strong cross-on SSW wind at 25 mph, it’s a complete mess. The combined energy is massive (5878) – plenty of power, but it’s all blown out and unrideable. That afternoon drops to 6 ft from the SE, but cross-shore wind keeps it lumpy. Thursday stays poor, with 5 ft and 4 ft swells and cross-chop. Friday morning 21 August finally brings a clean moment – a light NW offshore, 3 ft from the ESE at 10 seconds, and the combined energy is moderate (225). It’s surfable but average – a small, workable wave. Friday afternoon sees a 3 ft southerly swell, but the NE wind pushes it cross and the period jumps to 16 seconds – that’s a long-period groundswell, which can close out beach breaks but might offer a few lines if you pick your spot. Still, the conditions aren’t great.
Saturday 22 August morning is small and clean with a 2 ft SE swell and offshore WNW wind, but there’s barely any energy (45). The afternoon is the first real highlight: a clean, gentle offshore from the NW, 4 ft of southerly swell at a solid 12 seconds, combined energy of 347 – that’s moderate but punchy. Clean conditions, decent wave height, and good shape potential. This is a solid option for a Saturday session. After that, Sunday and Monday (23-24 August) drop back to tiny, clean but weak surf – not worth rushing out for. From Tuesday 25 August through to Friday 28 August morning, it’s downright flat: 0.7 ft to 1.0 ft swells, barely any energy (20-34), glassy or offshore winds but nothing to ride. A dead stretch of about four days with no surf on offer.
Friday 28 August afternoon throws a curveball – a 7 ft NNE swell, but with a short, weak period of 6 seconds, cross-offshore wind, and combined energy of 351. It’s marginal and likely choppy and messy. Not a goer.
Now for the standout window. Saturday 29 August morning is the pick of the whole forecast. A clean 5 ft NNE swell with a light NW offshore wind, period of 8 seconds, and combined energy of 481 – strong, punchy wave energy. That afternoon stays good with 5 ft from the NE, clean with a light WNW cross-offshore. This is the best on offer – solid size, decent shape, and clean conditions. Sunday 30 August morning is also a beauty: glassy calm, 4 ft NE swell at 8 seconds, combined energy of 313 – a smaller but still fun, clean session. After that, the wind swings onshore Sunday afternoon and stays poor right through Monday and Tuesday (31 August – 1 September), with cross-on winds and messy surf. Wednesday and Thursday (2-3 September) keep the onshore flow, and by Thursday afternoon it’s back to tiny, weak waves.
So, if you’ve got a session in mind, aim for Saturday 29 August morning – that’s the standout. Sunday morning 30 August is also worth a look. Everything else either needs a kite, or a good book.
Rusty.

Information about the Whangara Surf forecast
The above surf forecast table for Whangara provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Whangara can be found by selecting the local surf guide option on the grey menu. Our Whangara 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 (Whangara) 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 Whangara 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.
