The Lowdown
Alright folks, Rusty here. Let’s get into it for Raglan-Manu Bay.
We’ve got a 16-day window ahead, but honestly, it’s a bumpy road for most of it. The first week and a half is pretty much a write-off for decent surf. We’re looking at a lot of strong, cross-onshore winds and messy, lumpy conditions that are just not playing ball. The swell energy is all over the place, with some massive numbers in the thousands – like strong to very strong wave energy – but it’s all blown out. The water temp is about average for this time of year, nothing to write home about.
The first real glimmer of hope comes on Tuesday, 15 September. That morning, things shift. We’ve got a clean, light breeze coming from the east-northeast, which is a sweet cross-offshore wind for Manu Bay. The swell is a solid 6 ft from the west-southwest, with a period of 14 seconds – that’s proper groundswell energy. This is the standout of the whole forecast. The wave energy is moderate (1970), but the conditions are described as 'excellent for experienced surfers'. It’s a point break, so that long period will wrap in nicely, and the lack of wind chop will make for some glassy, lined-up walls. This is your best bet.
The days leading up to that are a grind. There’s a gap from now until that Tuesday morning with no real recommendations, except for a few marginal windows around Saturday, 5 September and Friday, 11 September, but those come with cross-onshore winds and choppy faces. The swell stays big – often over 8 ft – so this is expert territory if you’re even thinking about paddling out. Beginners, stay well clear of this whole period.
Rusty out.
