The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ at Piha over the next couple of weeks. It’s a bumpy ride, but there’s some real gold if you know where to look and are willing to wait.
The start of this run is rough. Wednesday the 26th is a no-go with 8ft of cross-onshore chop, and that junk keeps up through Saturday the 29th. Water temp is about normal for the season. There’s a small break in the clouds Thursday afternoon the 27th – waves drop to about 7ft, but the wind goes glassy from the north-northwest, so the lines will be clean. That’s for the experienced crew only, but it’s your first real chance.
Then things turn nasty. Sunday the 30th brings 10ft to 15ft of swell with a short 8 to 9 second period, and the wind howls at 22 mph onshore. Total chop and lump – leave the board at home.
Monday the 31st we get a proper monster: 20ft of WSW swell with a 14-second period, and the wave energy is screaming at 15802. That’s too big for all but the most skilled, and the wind is 19 mph cross-shore making it lumpy. Tuesday 1st of September is still huge at 13ft to 15ft with cross-shore wind. No good.
Things settle by Wednesday 2nd, but it’s still 10ft with a 14-second period and choppy cross-onshore wind. Not your day.
Now, listen close: the standout is Sunday the 6th of September. Both morning and afternoon we’ve got 12ft of WSW groundswell with a very long 16-second period, glassy conditions with the wind barely 3 mph from the north-northeast, and the wave energy sitting at 6118 to 6624. That is exceptional, clean, powerful surf – and it’s only for experts. That long period means the sets will be well-spaced and the waves will stand up nicely.
Monday the 7th still holds strong at 10ft with a 16-second period, but the wind kicks up to 9 mph cross-shore, so it’s not as pristine.
After that, we’re into smaller stuff. Tuesday the 8th and Wednesday the 9th are around 7ft to 8ft with shorter periods and mostly onshore breezes. Thursday the 10th has another 12ft swell with a 16-second period, but the wind is a strong 22 mph cross-offshore from the east-northeast – clean, but gusty as hell.
There’s a big dead patch of poor conditions at the beginning. If you’re not an expert, this whole forecast is a pass. The one to mark on your calendar is Sunday the 6th of September – that’s the real deal.

A general guide to surfing at Piha-The Bar 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 Piha-The Bar 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.
