Alright, Rusty here. Let's talk about what's coming up at Whangamoa.
Well, mate, I gotta be straight with you – the next week and a half is a bit of a flat spell for Whangamoa. We've got a long stretch of small, weak, and mostly poor conditions to get through. It’s not looking like a classic winter run. There’s a big gap of quiet days from the start, through the 13th and 14th, with barely anything worth paddling out for.
On Tuesday the 14th, we finally see a tiny pulse. Early morning, with a glassy clean surface and a 4ft swell from the NNW. It’s got some push, with moderate wave energy (196), but the wind stays clean until it swings onshore later. Still, the wave quality is described as ordinary, so don't expect anything special.
Wednesday the 15th is similar – a clean morning showing 3ft from the NNW, but it's weak energy (66). That’s a common theme for a few days; little bumps but nothing with any real grunt. We then hit a proper lull from the 16th through to the 24th. Days with flat conditions, or only tiny, short-period dribble, and not a single score above "poor surf conditions." Lots of offshore winds through that period, which is a tease – clean conditions but no swell to work with.
The first real standout comes in on Sunday, July 26th. Now we’re talking. The morning shows 6ft of NNW swell with strong energy pushing through (241). Wind is glassy, from the south, so the setup will be clean as a whistle. That's the best on offer across the whole outlook. It's a solid, surfable wave, though with that short period (6 seconds), it’s not going to be a classic groundswell – more of a windswell bump. On the 26th morning, this is the day to pencil in. Given it's over two weeks away, keep an eye on it – forecasts for that range can shift. The crowds here are never an issue, so you'll have plenty of space. Water temp is about 56°, which is normal for this time of year, so a decent steamer is the go.
Beyond that, Monday the 27th drops off quickly, with small surf returning. Tuesday the 28th afternoon brings a late pulse of 4ft from the NNW and strong energy (312), but the wind turns onshore, making it marginal.
So, to sum it up: don't bother with the first couple of weeks. Save your energy for Sunday morning, July 26th, which looks like the only real session on the cards. It’s not perfect, but it’s the clear highlight of a quiet period.
Rusty.

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.
