The Lowdown
G'day, I'm Rusty, and here's what's shaking on the Raglan coast for the next 16 days. We're looking at a pretty grim start with a lot of wind and messy conditions, but there's a light at the end of the tunnel for the middle of the second week.
The first week is a write-off, unfortunately. It's all about a strong, powerful groundswell from the WSW, but the wind is just relentless. From Tuesday the 1st through to Monday the 7th, we're dealing with strong to fresh cross-shore and cross-onshore breezes, which is just trashing the surface. There's plenty of energy in the water – with combined energy readings in the thousands (6101 on Tuesday morning) – but it's a messy, choppy, cross-chop mess. The water's sitting at 57°, which is pretty normal for this time of year.
We get a bit of a reprieve from the wind on Thursday the 9th morning, with a light breeze, but the swell is down to 5ft and it's still a bit onshore. The energy is moderate (712). It's still a bit of a gamble. Then we get a weird one on the 10th – a pulse of swell with a super long 21-second period, but winds are strong and cross-shore, so it's not going to be pretty.
Now, the first real standout shows up on Tuesday the 15th of September. The wind swings to a light ENE cross-offshore, and the swell is still a solid 6ft from the WSW. The energy is moderate (1413), and it's described as "clean." This is the best session on offer, and the Manu Bay point will be handling this long-period groundswell beautifully. It's a bit of a decent size, so it's for the more experienced crew, but it's going to be pumping.
The next day, Wednesday the 16th, offers another good option. The wind turns clean offshore from the ESE, with a light 9 mph breeze. The swell is a bit smaller at 5ft, which is excellent for a broader range of surfers, and the energy is moderate (977). It's a bit more manageable and will be super clean. This is a solid second-choice.
So, the long story short: the first week is a complete washout. The second week starts to look more promising, with the 15th and 16th being the real windows to get out there and score. Don't bother paddling out before that. Keep it on the radar, eh?
Rusty.
