The Lowdown

Alright, Rusty here. Let’s have a look at what’s in store for us over the next couple of weeks.

First up, we’re looking at a pretty quiet start to the period. The surf is tiny and the conditions are pretty ordinary, so don’t bother paddling out just yet. We’ve got a few days of barely anything until things start to pick up.

The first real sign of life comes on Tuesday the 8th. The swell jumps to about 4ft from the SSE, but the wind is coming from the south, putting it straight onshore for Wainui Beach - Stockroute, and the period is a short 8 seconds. It’s a bit messy, so it’s more of a wait-and-see. The combined energy is moderate (261).

Wednesday morning the 9th is still a bit average, with a 4ft ESE swell, but the wind is a light cross-shore, so it’s not all bad. The energy is still moderate (206). Thursday the 10th has a tiny 2ft swell from the ESE with a clean offshore wind from the NW, but it’s just too small to get excited about.

Now, things start to get interesting on Friday the 11th. The afternoon brings a solid 7ft swell from the south, but the period is a short 6 seconds, so it’s a bit lumpy. The energy is getting strong (798). Still, the wind is light and cross-shore, so it might be worth a look for the more experienced crew.

The real standout, though, is Sunday the 13th. This is the one. The morning shows a 10ft swell from the SSW with a long, proper 11-second period, and the wind is howling offshore from the WNW at 19 mph. The combined energy is huge (3243). This is a serious groundswell, and at this size, it’s strictly for the experts. The afternoon cleans up nicely with a 6ft swell from the SSE, a 13-second period, and still offshore. The water temp is about average for this time of year, so don’t expect any surprises there.

Monday the 14th morning is another cracker – 8ft from the SSE with a 14-second period and light offshore wind from the WNW. The energy is massive (2155). This is another day for the experienced surfer only. The afternoon goes a bit onshore, so get out early.

The next week continues to deliver. Tuesday the 15th morning has a nice 4ft swell from the SSE, 12-second period, and light offshore wind. The energy is moderate (558). This is a solid, clean wave for the intermediate surfer. Wednesday the 16th and Friday the 18th both offer clean, offshore conditions with 3ft and 5ft swells respectively, perfect for a sneaky session.

But the final big standout is Saturday the 19th. The whole day is a goldmine. A 10ft swell from the SSE, 10 to 11-second period, and offshore wind all day. The energy is extreme (over 1700). This is a serious, powerful swell. Again, this is for the experts only, and you’ll want to be early to beat the crowds, because this spot is known to get busy.

To wrap it up, the best sessions are undeniably Sunday the 13th and Saturday the 19th at Wainui Beach - Stockroute. The swell direction from the SSE is bang on for this spot, the wind is perfect, and the energy is full-on. The water is around average for the time of year. If you’re an experienced surfer, get amongst it. If you’re a beginner, stay well clear on those big days.

Rusty.
