The Lowdown
Alright, mates. Let’s talk about Manu Bay at Raglan. Water temp is sitting around 57°F, right where it should be for this time of year – nothing strange.
We’ve got a solid run of surf coming our way. It kicks off this Saturday morning, the 15th, with a clean 6ft WSW groundswell, a long 17-second period, and a light south cross-off breeze. The wave energy is pumping at 1749. Good stuff for experienced surfers, but the long period means it’ll be better on this point, with longer waits between sets.
Sunday morning, the 16th, the swell builds to 8ft from the WSW, still a 16-second period, and clean with a light southerly cross-off. Energy jumps to 2901. This is getting solid – too much for beginners, but for the experienced crew, it’s a ripper. Sunday afternoon sees a shift to a light SSE offshore, keeping it clean.
Monday the 17th hangs in there with 7ft WSW swell and a 15-second period, clean in the morning, and a bit of a breeze in the afternoon but still rideable. The energy stays strong around 1976.
Tuesday the 18th drops a little to 5ft, still clean but the energy drops to 811. Still fun, but the swell is backing off.
The standout? Without a doubt, it’s Tuesday the 25th. Early morning we’ve got a massive 10ft WSW groundswell with a 16-second period, light SSW cross-off breeze, and the energy is a beast at 4779. This is pure power – experts only, but absolutely firing. The following Wednesday morning, the 26th, is also a gem: glassy conditions, 8ft WSW swell, 16-second period, and energy at 2901 – smooth as silk.
There’s a bit of a flat spell from the 21st to the 23rd, with onshore winds and small, messy waves. The 23rd even sees a junky 7ft NW windswell with a 7-second period and onshore winds – that’s kite-surfing territory, not much for paddling.
After that, the 29th and 30th show some promise with a new WNW swell, 8ft, clean offshore winds, and solid energy. The 30th Sunday morning is looking choice: 8ft WNW, 12-second period, 9 mph SE offshore, energy at 2230 – another one for the experienced crew.
Stay safe out there, and remember – Manu Bay can handle the size, but it’s a long paddle if you’re not ready.
