The Lowdown
G’day, Rusty here.
First thing’s first: we’ve got a bit of a dry spell before anything worth paddling out for. The next few days are a write-off—small leftovers and bumpy conditions from the 6th through to the 9th. If you're itching for a wave, you’ll be fighting onshore slop, so save your energy. There’s a real gap here before things turn on.
The first proper window shows up on Monday the 10th. We’ve got a jump in size to 7 ft from the NNW, but the real story is that clean, cross-off SSW breeze. The energy is solid at 1557, and while it might be a bit much for beginners, experienced surfers will find plenty to sink their fins into. Waiwakaiho (Taranaki) will be the spot, offering up some proper walls.
Tuesday the 11th shapes up as a lighter option – around 3 ft, but still with a clean cross-off ESE airflow. The swell energy drops to 570, so it’s not as powerful, but it’s a pickable, manageable day.
We get another pulse on Friday the 14th. The morning brings a clean 5 ft, but the afternoon is the true standout: 6 ft of W swell with a 17-second period and the wind goes glassy. This is one of those windows where the ocean feels like a mirror and the lines are long. The energy is reading 1749, so there’s real push behind it. This is the best of the first week, hands down.
Saturday the 15th keeps the energy high – the morning sees 7 ft from the WSW with a 20-second period and clean cross-off conditions. This is a big, powerful groundswell, so it’s for experienced crews only. The energy is massive at 3741. This is another standout, though the wind will junk it up in the arvo, so get out early.
After that, things get a bit more ordinary. Sunday the 16th and Monday the 17th still have size, but the wind turns onshore and fresh, making for messy, lumpy conditions. It’s a battle for a wave, and you’ll be working hard for it.
The middle of the second week looks weak – the 18th and 19th see the swell drop to around 3 ft with that WSW direction. It’s clean, but small. Patience will be your friend.
The last decent window we’re looking at is Thursday the 20th. A glassy morning with a clean 3 ft from the WSW. It’s a fun, user-friendly size with the energy at a modest 382. It’s not a world-beater, but after the run we’ve had, it’ll feel like a holiday.
So, to sum it up: the standout days are the afternoon of the 14th and the morning of the 15th. That’s where you want to be. The rest is waiting for the ocean to get its act together. Stay patient, and when it's on, it's on.
Rusty, signing off.

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