The Lowdown

G’day, Rusty here. Let’s have a look at what’s coming up for Wainui Beach – Stockroute.

We’re in for a bit of a slow start, but the second week is where the real juice comes through. This is a beach and reef setup, exposed to the swell, and it needs a clean window to really fire. The water temp is sitting about average for this time of year, nothing unusual.

The first few days are pretty flat. Friday 24 July and Saturday 25 July offer tiny, weak swell – 1ft to 3ft – with short, weak periods. The combined energy is low (36 to 249), and the wind is cross-off but the waves just aren’t there. Not worth paddling out. Sunday 26 July sees a jump in size to 7ft from the S, but the period is a short 8 seconds and the wind swings cross-shore, making it a bit of a mess. The energy picks up (1103), but the quality is marginal.

Monday 27 July is where things start to look up. Morning shows 4ft from the ESE with a 13-second period, light cross-off breeze, and clean conditions. Energy is moderate (574). It’s a good, solid session. The afternoon gets a bit bigger at 5ft but the wind turns cross-shore, so the morning is the pick.

Tuesday 28 July morning is the standout of the first week. We’ve got 6ft from the ESE, a 13-second groundswell, and offshore WNW wind at 6 mph. The energy is strong (1041) and the conditions are clean. This is excellent surf for experienced surfers. The big, long-period swell will be lining up nicely on this reef-and-beach combo, but be aware – it’s a bit much for beginners. Crowds are possible here, so get in early.

The rest of the week drops off a little. Wednesday 29 July is still fun at 5ft with clean mornings, but the energy is moderate. Thursday 30 July and Friday 31 July fade to around 3ft to 3ft, with cleaner conditions but smaller waves.

Now, Saturday 1 August and Sunday 2 August are the real standouts of the whole 16-day window. Saturday morning sees 7ft from the S, 8-second period, but with offshore NW wind at 3 mph – glassy conditions. The energy is very strong (1130). This is excellent for experienced surfers. Sunday morning is similar: 8ft from the S, 10-second period, offshore NW wind at 6 mph, and energy at 1530. Both mornings are clean, powerful, and punchy. These are the days to circle. The afternoon winds swing onshore, so mornings are everything.

Monday 3 August drops back to 5ft with moderate offshore wind and clean conditions. Then Tuesday 4 August offers a 4ft swell from the SSE with a 13-second period, but the wind is cross-off and the energy is moderate (640). Worth a look, but not the best.

Wednesday 5 August is a write-off – strong S wind, 10ft swell, but the wind is cross-shore and messy. Energy is very high (2392 to 2707), but it’s blown out. This is more for kite surfers than paddle surfing.

Thursday 6 August morning is another gem. 6ft from the SSE, 15-second period – very long period groundswell – with offshore NW wind at 6 mph. Energy is strong (1237) and it’s clean. This will be a dream for point breaks or reefs, and on this beach-and-reef setup, the long period will give long, clean lines. Excellent for experienced surfers.

The last few days, Friday 7 August and Saturday 8 August, see a return to smaller, shorter-period swell (7ft, but only 8-9 seconds, with cross-shore wind) and then a drop-off to 4ft with fresh wind and poor conditions.

So, to wrap it up: the best on offer is Tuesday 28 July morning for a clean, solid session, and the Saturday 1 August and Sunday 2 August mornings for the big, powerful, offshore barrels. The Thursday 6 August morning is also a treat for those who love long-period groundswell. Get after it.

Rusty.
