The Lowdown

Alright, folks, Rusty here. Let's talk about what's coming up for Wainui Beach - Stockroute. This is a beach and reef setup, advanced territory, and it's very consistent – so even when it's not pumping, there's usually something to work with. The water's a bit colder than usual for this time of year, sitting at 56°F with a -3°F anomaly, so you'll want a good wetsuit.

The forecast starts with a bit of a mixed bag. Sunday the 19th afternoon has waist-high SSE swell at 4ft, but a crosswind and moderate energy (1269) mean it's pretty average – not worth getting excited about. Monday the 20th is similar: morning drops to 3ft, but the afternoon pulses back to 5ft with a 19-second period and 1848 energy. Still, the wind is cross-shore both sessions, so it's messy.

Tuesday the 21st is where it gets interesting. The morning session is the standout of the whole 16-day window: a clean 5ft SSE swell, 16-second period, and a light WSW cross-off breeze at 3 mph. The combined energy is 1405 – strong, but not overwhelming. This is a true gem for experienced surfers. The afternoon is still decent at 5ft but the wind swings cross-on, so it's not as clean.

Wednesday the 22nd fades fast – morning has 3ft with a NW offshore, but the energy is low (291). By Thursday the 23rd, it's tiny (2ft) and dropping. From Friday the 24th through the weekend, the swell drops to knee-high or less – almost flat. Saturday the 25th has a 2ft windswell but a fresh offshore, so if you're desperate, it's glassy but tiny.

The second week starts to pick up again. Sunday the 26th afternoon shows a 2ft ESE swell, 13-second period, and a clean offshore wind (W 12 mph). It's small but clean. Monday the 27th morning has a 3ft SSE with a fresh offshore, but the wind is strong (19 mph). The afternoon jumps to 5ft, but the period drops to 8 seconds and the wind is howling – not great for paddle surfing.

Tuesday the 28th brings a bigger swell: 6ft in the morning, 8ft in the afternoon, both SSE with long periods. But the wind is near gale force (31 mph) – that's kite territory, not a clean surf session. Wednesday the 29th settles to 5ft with a cross-off, but still windy. The rest of the week into August 3rd has small, mostly clean but marginal waves.

The real standout is Tuesday the 21st morning. It's the only session that combines a decent size, long period, and light offshore wind. Crowds are possible – it's "sometimes" busy, but on a Tuesday morning you might get lucky. The swell direction (SSE) is exactly what this spot likes. If you're an advanced surfer, that's your window. Everything else is either too small, too windy, or just average.

Rusty.
