The Lowdown

Alright, Rusty here. Let’s talk about what’s happening at Wainui Beach – Stockroute.

For a bit of a slow start, the water temp is sitting at 57°F which is about normal for this time of year, so nothing weird going on there.

First real chance to get wet comes in Wednesday afternoon, July 15th but it’s pretty weak. We’re looking at tiny 1ft surf from the ESE with a short 10-second period, and combined energy is only 40 (weak). It’s glassy though, so if you’re desperate for a paddle you could get out there, but it’s not going to be memorable.

Thursday July 16th morning kicks up a gear. The swell picks up to 2ft from the ESE with a 15-second period, giving us 182 combined energy (moderate). The big news is the wind: clean offshore from the NW at 15 km/h. That’s going to be clean and lined up. Afternoon gets even better: 2ft, 18-second period, 366 energy, and WNW offshore at 10 km/h. This is where it starts to feel like a proper session.

Now the standout. Friday July 17th morning is the pick of the early run. 5ft from the ESE, 16-second period, 1065 combined energy (strong), and light offshore NW wind. That’s excellent surf for experienced surfers. The swell direction is a solid match for the optimum SSE, and the period is long enough to give you real power. Crowds can be an issue here sometimes, but with that quality, it’ll be worth sharing a few waves.

Friday afternoon sees the swell bump to 5ft but the wind goes cross-on from the ENE, so it’ll get a bit lumpy. Saturday morning July 18th is still clean with 4ft and cross-off wind, still good.

Sunday July 19th morning brings another big moment: 5ft from the SSE, 19-second period (very long period groundswell), and 1786 energy (strong to very strong). Light offshore wind from the SW. This is a treat for the reefs and points, but a beach break like this might get a bit straight with that long period. Still, for the crew that knows where to sit, it’s going to be special.

After Sunday, the surf drops off but stays rideable through the middle of the week. Monday July 20th morning is clean with 4ft, and Tuesday July 21st morning has another clean 5ft from the SSE with offshore W wind. That’s still a solid option.

From Wednesday July 22nd onward, the swell slowly fades. By July 24th and 25th we’re down to 2ft and 1ft, energy dropping below 100. The last week of July is mostly small and weak, with a few clean but tiny days.

Then on July 30th, Thursday morning, a big pulse hits: 8ft from the S at 10-second period, 2018 energy (very strong). That’s expert-only territory, and the wind is cross-off from the SW at 25 km/h. It’ll be clean but powerful and heavy. Not for the faint-hearted.

Bottom line: Friday July 17th morning is your best bet for quality, clean, powerful surf. Sunday July 19th morning is the other big call if you can handle the long period.

Rusty.
