G'day, I'm Rusty. Let's have a look at what's shaping up for Wainui Beach - Stockroute.

Alright, the first week and a half is pretty ordinary, to be honest. We've got a bit of a flat spell and then some messy, onshore junk. The real standout, the one you want to circle on the calendar, is Friday the 17th of July. That morning, we're looking at a clean 4.6ft swell from the ESE with a nice long period of 16 seconds – that's proper groundswell energy (1034 combined energy). The wind is light offshore from the WNW, which is going to have it glassy. This is a steep, fast wave, so it's going to be one for the experienced crew. The water temp is sitting around 57.2°, which is pretty much what you'd expect for this time of year.

The build-up to that Friday isn't much. Monday the 13th has a tiny 2.6ft wave from the ESE with a cross-offshore breeze, but it's just surfable, not worth getting excited about. Tuesday and Wednesday are flat with tiny waves. Thursday the 16th has a small 2.0ft swell in the morning, but it's the afternoon that shows a bit of promise with a 1.6ft swell and a 17-second period (255 energy) under offshore winds – clean but small.

Now, Friday morning is the pick. That 4.6ft, 16-second ESE swell with light offshore WNW wind is going to be clean and lined up. It's a powerful wave, but with that long period, it might be a bit straight on the beach, so watch for the better sections. The afternoon sees the wind swing to a cross-shore SSW breeze at 12 mph, and the swell bumps up to 5.2ft, but that wind will put a chop on it, making it less appealing.

Saturday the 18th is still good. The morning has a 4.3ft ESE swell at 14 seconds (1051 energy) with a light cross-offshore breeze – clean and fun for the experienced. The afternoon stays similar with the same size and a light wind. Sunday the 19th is a write-off with strong cross-shore winds and a lumpy mess.

Then from Monday the 20th, things get bigger but messier. We get a 7.9ft S swell, but it's short period at 10 seconds and cross-shore winds, making it a bit of a washing machine. That's more of a kite-surfing setup than a paddle session. The week after that just gets worse with onshore winds from the east and south-east, keeping the surf poor and choppy right through to the end of the month. There's a bit of size on Saturday the 25th with a 7.2ft SSE swell, but it's onshore and lumpy.

So, bottom line: if you're an advanced surfer, be on Wainui Beach - Stockroute early Friday the 17th. That's your window. The rest is a long wait for clean conditions.
