The Lowdown
Alright, Rusty here. Let's have a look at what's shaking for Raglan-Manu Bay.
Right off the bat, the next week and a bit is looking pretty grim for a proper surf. We’ve got a big, messy storm cycle moving in, so you can basically write off the next few days for any quality time on the point. The water temp is sitting at 57°, which is pretty much what you'd expect for this time of year.
This Saturday the 29th, there’s a tiny bit of swell around 4ft from the WNW in the morning, but it’s cross-shore and a bit weak with only moderate energy (392). The afternoon cleans up nicely with glassy conditions and a 2ft swell from the WSW, but it’s just too small to get excited about.
Sunday the 30th kicks off a run of strong south-westerly winds. The swell builds fast, hitting 8ft by the afternoon, but with a cross-shore, lumpy mess. The combined energy is huge (3580), but it’s all blown out. Same story all the way through to Thursday the 5th of September – plenty of size, but the wind is just trashing it. We’re looking at a solid week of poor conditions.
Finally, things start to look a bit more promising around the 7th of September. Monday the 7th is the standout. The wind goes light and glassy or cross-offshore, and the swell sits at a solid 7ft to 8ft from the WSW. The period is nice and long (14-17 seconds), which is a proper groundswell. This is an advanced wave, and with those conditions, Manu Bay will be offering up some proper, long, wrapping lines. The energy is off the charts (3113-3847), so it’ll be powerful.
After that, the size jumps up again, with a huge 16ft+ swell hitting on the 9th and 10th of September. That’s big, dangerous stuff, especially on a west-northwest wind. Not one for the faint-hearted. Look to the 12th of September for another clean-up, with an 12ft swell and light offshore winds in the morning. That's another day for the experienced crew.
So, if you can wait, the pick of the bunch is Monday the 7th of September. Get out there early for the glassy conditions and a serious, long-period groundswell.
Rusty.
