The Lowdown

Righto, Rusty here. Let’s have a look at what’s coming down the pipe for Port Waikato-Sunset Beach. It’s a bit of a slow starter, but there’s some serious juice building later in the week.

The first few days are pretty quiet. Wednesday the 12th is a write-off – small 3ft swell from the WSW with a cross-off wind, and the energy is weak (411). Not worth paddling out for. Thursday the 13th shows some promise though. The morning sees the swell nudge up to 4ft from the WNW, but it’s a short period of 10 seconds, so it’ll be a bit lumpy. The real standout is Thursday afternoon – glassy conditions with the wind dropping to nothing, and the swell bumps to 5ft from the west with a 12-second period. The energy is strong (1084), and it’s clean, glassy perfection. That’s the session to aim for if you’re an intermediate or above.

Friday the 14th is a solid goer too. The morning brings 6ft from the WSW with a long 16-second period, offshore wind from the east, and the energy is pumping (1594). The afternoon gets a bit messy with a cross-shore wind, but the morning is clean and powerful. Saturday the 15th sees the swell climb to 6ft, but the cross-wind picks up, making it a bit of a chop-fest. By Saturday afternoon, it’s 8ft and the wind is howling at 25 km/h – that’s getting big and blown out, more for the experts who don’t mind a beatdown.

Now, Sunday the 16th is where it gets serious. The morning has 7ft from the SW, 16-second period, and a clean cross-off breeze. The energy is massive (5314). This is proper groundswell – long, powerful lines. But it’s big, so only for experienced surfers. The afternoon pushes 10ft, and the file says it’s too big for this break. That’s a warning – if you’re not solid, stay out. Monday the 17th stays huge at 10ft, but the wind is stronger, making it a handful.

The best on offer for the week is that Thursday afternoon glassy session, and the Sunday morning clean swell. After that, the swell drops but stays fun. Tuesday the 18th morning has 6ft from the WSW with a light cross-off, clean and good for experienced surfers. Wednesday the 19th morning is another glassy gem with 5ft and a clean cross-off, and the afternoon goes glassy with 6ft from the WSW, 16-second period – that’s a beauty.

The second week gets a bit quieter. From the 20th onward, the swell steps down. Thursday the 20th morning has 6ft from the SW, clean, but the afternoon turns onshore. Friday the 21st is smaller, 5ft, and the wind is okay in the morning. The real standout in the second week is Saturday the 22nd morning – glassy, 4ft from the SW, 14-second period, clean and fun for all levels. After that, it fades to 3ft by Sunday the 23rd, and the last few days of the outlook are poor with onshore winds and small, weak swell. The water temp is sitting at 56°, which is pretty normal for this time of year, nothing unusual.

So, to sum it up: Thursday afternoon and Sunday morning are the standouts. Get out there for the glassy, clean sessions. The big stuff mid-week is for the experts only. After that, it’s a slow fade, so make the most of the coming days.

Rusty.
