The Lowdown
Alright, let’s get into it. Rusty here, and I’m looking at a couple of weeks that start rough but turn into something special.
We’re coming in hot on Saturday the 12th with a massive 13-foot west-southwest swell, the energy is off the charts at 7489. But it’s blowing 35 km/h from the southwest, right across the face. It’s going to be a bumpy, wind-blown mess. You’d be mad to go out for that. The model gives it a big fat zero. That size hangs around for the first few days, easing to around 8-10 feet by Monday the 14th, but the cross-shore wind just ruins it. It’s lumpy, choppy, and a real battle.
The middle of the week is a write-off. We drop right down to under 3 feet on Wednesday the 16th, with onshore winds. There’s just nothing doing. The swell tries to pick up again on Thursday the 17th but it’s coming from the north with the wind, so it’s not going to be any good.
Now, here’s where the story changes. Around Friday the 18th, the wind swings offshore to the east-southeast and Manu Bay (Raglan) starts to clean up. The swell is a manageable 5-6 feet and it becomes *crisp*. Water temp is around 58°, which is pretty normal for this time of year.
The real sweet spot is from the 20th through the 27th. This is the window you’ve been waiting for. We get a run of days with light winds, often offshore or even glassy. Sunday the 20th looks epic—a solid 10-foot west-southwest swell with a light southeast breeze. The energy is pumping at 3808. The Monday after, the 21st, it’s still 8 feet with a light southerly—another standout. This is for experienced surfers only, but if you’ve got the skills, these are the days to be out there.
We get another good run around Thursday the 24th and Friday the 25th. The swell holds at a powerful 8 feet with a long 14-16 second period, and it’s glassy in the mornings. Perfect for a point break like this.
The last couple of days, the 26th and 27th, keep the quality high. The swell eases to a fun 6-7 feet, but the wind is still light and offshore, and the period is long, pushing 17 seconds on the last day. It’s consistent, it’s clean, and it’s got plenty of punch. So, yeah, the first week is a bit of a dud, but from the 20th onwards, it’s going to be well worth the wait.
