The Lowdown
G’day, Rusty here. Look, I’ll level with you—this outlook for Port Waikato-Sunset Beach is a rough one. We’ve got a 16-day window, but the first decent surf doesn’t show up until over two weeks from now, on the morning of Thursday, September 10. Before that, it’s pretty much a write-off. There’s a long gap of nothing worth paddling out for from now until then.
The water temp at Port Waikato-Sunset Beach is sitting at 56°, which is about average for this time of year—nothing unusual there.
Alright, let’s run through the misery. From Wednesday, August 26, we’ve got a solid 8 ft swell from the WSW, but with a 15 km/h cross-onshore wind, it’s choppy and messy. The wave energy is very strong (2218), but the conditions are just poor. That theme continues through Thursday and Friday—swell sticks around 7 ft to 6 ft, but the wind is never clean. Saturday brings light rain and a 8 ft swell, but again, cross-shore wind messes it up.
The end of August and start of September is a total loss. The swell jumps big—10 ft, 13 ft, even 15 ft on Monday, August 31—but with fresh cross-onshore winds hitting 30 km/h, it’s lumpy, choppy, and dangerous. The combined energy is massive (7312, 7221), but this is a beach break, and with that much wind and size, it’s more of a kite-surfing setup than a paddle session. The swell is way too big for beginners, and honestly, even experts would struggle with the conditions.
We get a bit of a break around Thursday, September 3, and Friday, September 4, with 12 ft to 10 ft swell and winds turning more onshore, but the swell is still too big for this break. The guidance says the swell is predicted to be too big for the spot. No good.
Finally, on Thursday, September 10, we see a glimmer. The morning brings an 8 ft swell from the WSW, with a period of 13 seconds—that’s decent groundswell energy. But the real standout is the wind: glassy conditions, with a 5 km/h breeze from the north. The water is clean. The combined energy is still strong (2081), but the size (8 ft) means this is only for experienced surfers. It’s the only real window in the whole 16 days. The afternoon shows a slight drop to 8 ft and a light WNW onshore breeze, so the morning is the one to aim for.
That’s your lot. One morning, two weeks out, that could be worth a look. The rest? Leave the board in the car.
Rusty.
