The Lowdown
G’day, it’s Rusty here.
Alright, let’s be straight with you. The next couple of weeks are a mixed bag at Wainui Beach – Stockroute. We’ve got a slow start, a definite window of quality in the middle, and then a long stretch of small, wonky surf to finish it out. Don’t get too excited about the first few days, because we’re scraping the bottom of the barrel for a wave.
Thursday morning kicks things off with a weak 2ft SSE swell at 7 seconds. The energy is barely there at 62, and while the NW breeze keeps it clean, it’s just not doing much. The afternoon cleans up a touch with a light WNW offshore, but it’s still tiny at 2ft. Honestly, this is just a paddle-around kind of day.
Friday drops off hard. Morning sees a 1ft SSE pulse, but it’s got a super long 19-second period, so it’s walled up and weak. The light rain and SW cross-off wind don’t help. By the afternoon, the swell bumps a touch to 2ft but the onshore SE wind messes with it. This is not your day.
Saturday is more of the same struggle. Swell hangs around 1ft to 2ft, but the wind is all over the place – cross-off in the morning, then a choppy cross-on in the afternoon. The energy is still weak, no real push. Skip it.
Now, hang on, because Sunday morning is the standout of this whole forecast. The swell jumps to a solid 6ft from the SSE at a nice 14-second period. The combined energy is a strong 1384, which is the most powerful we see in this whole window. We’ve got a light WNW offshore wind and it’s clean. This is a proper session for the experienced crew – the size is there, the power is there, and it’s going to be firing. The afternoon stays around 5ft but a moderate S cross-shore breeze starts to chop it up, so get your waves in early.
Monday keeps the size but loses a bit of quality. Monday morning has 5ft SSE at 12 seconds with a light N cross-off wind – that’s a good, clean wave and a solid option. The afternoon drops to 5ft but the SE onshore wind makes it a bit of a mess.
Tuesday fades out. There’s a glassy 3ft SSE swell in the morning with a 5 km/h NW wind – clean and fun on the longboard, but the energy’s only 229. The afternoon gets small and choppy.
Wednesday and Thursday are pretty ordinary. We’re back to 2ft or under, with light winds but tiny waves. The energy has completely drained out of the system.
Friday (the 18th) gets a little interesting. The morning is just 1ft, but the afternoon sees a pulse to 3ft SSE at 9 seconds with a gentle offshore NW wind. It’s a clean, playful wave, nothing serious, but it’s a bit of fun if you time it right.
Then we hit the long, slow grind from Saturday the 19th through to the end of the forecast. The swell is consistently small, mostly under 3ft. There’s a little bump on Monday the 21st – 3ft SSE at 14 seconds with a moderate offshore NW wind – but it lacks the size and power to get the heart racing. After that, it’s all tiny leftovers and cross-on breezes. The energy barely cracks 200 on any of those days.
So, to sum it up: if you want waves, your window is Sunday morning the 13th. That’s the clear standout – big, clean, and powerful. Monday morning is the backup. After that, prepare for some flat spells.
Signing off,
Rusty
