The Lowdown

Alright, mates, Rusty here again. Let’s break this down for the next couple of weeks. It’s a real mixed forecast, plenty of size but a lot of it either too big or blown out. The long-range stuff is promising, but that’s a ways out, so we're keeping an eye on it. That first big pulse is for the brave only, and there’s another one coming that could be the winner if the conditions hold.

Starting with Thursday morning, the 6th. Wainui Bay Chalet is pumping, but it’s a monster. We’ve got a solid 10ft of south swell, with 11-second period. That’s a ton of water, and the energy is through the roof. The wind is cross-offshore from the west, which will keep it a bit tidy, but at this size, it’s a proper beast. Only for the experienced crew.

The afternoon sees the swell back down to 7ft, but the wind comes onshore and chops it all up. Not good.

Friday the 7th morning is much better. Swell drops to a more friendly 5ft from the southeast, with a 10-second period. The key here is the light offshore breeze from the west-northwest at 6 mph. That’s going to give us some clean, glassy conditions. There’s decent energy in the water, and this could be a fun one for the intermediates. The afternoon gets a bit messier, so make the most of the morning.

Saturday the 8th is a similar story. Morning has 5ft of south-southeast swell with a light offshore wind. Very clean. Similar size to Friday, but the conditions should be good. Another solid option for an early surf.

Sunday the 9th sees the swell drop to 3ft. The morning wind is a stronger offshore, but it’s still clean. It’s surfable, but the energy is fading. Afternoon is a bit small and cross-off, not much excitement.

Monday the 10th is a complete washout. Tiny swell and poor conditions. The energy is weak. We’re heading into a proper flat spell here for the next few days.

Tuesday the 11th morning gives a small window. There’s a 3ft south-southwest swell but with a short 7-second period. The wind is glassy, though – dead calm. That’s a big positive. It will be clean, but it’s small and lacking punch. Worth a look if you’ve got the itch. After that, Wednesday and Thursday are pretty poor.

We go through a real flat spell from the 12th to the 17th. Very little energy and a lot of onshore junk. It’s going to be a barren run. Don’t bother. Not worth the effort.

Now, for the serious stuff. Check out Tuesday the 18th. Huge jump in size. The model is showing a 13ft swell from the southeast with a 12-second period, and the energy is massive. The morning wind is a light cross-offshore, which could be good, but this is way too big for this break. It will be a close-out. It’s going to be a washing machine. Only for the absolute experts, and even then, think twice. The afternoon is blown out with a near-gale onshore wind. Wednesday the 19th is also too big and messy.

The real standout, the one to get excited about, is Thursday the 20th. The swell has dropped to a much cleaner 6ft from the east-southeast. The wind is a light offshore from the west. That’s the combo we want. The energy is still strong, and it’s going to be clean. This is the one. It won't be as big as Tuesday, but it will be far better quality. Get on it.

Friday the 21st has a 8ft easterly swell, but the period is short, and it might be pushing the limit for this spot. The morning wind is light and cross-offshore, which is good, but the short period and size could make it a bit unruly. It's promising, but not a sure thing. We’ll be watching that one.

So, there you go. The first week is for the brave, with a couple of good mornings on Friday and Saturday. Then a proper flat spell. But mark the 20th down. That’s your best bet for a classic day. It’s a long way off, so don’t book the day off work yet, but it has real potential. Later, Rusty.
