The Lowdown

G’day, Rusty here. We’ve got a solid 16-day run ahead at Wainui Beach – Stockroute, but you’ll need to pick your moments. This spot is a consistent, exposed beach and reef setup that likes a good SSE groundswell, and the water’s sitting at 56° – that’s about 2°F cooler than average for this time of year, so you’ll be glad of a decent steamer.

The first real chance to get wet comes Saturday morning, 1st of August. It’s a bit of a mixed bag though – a 7ft SSW swell (moderate energy at 1084) but with a 16 mph cross-offshore wind out of the SW. It’ll be clean, but the wind is a touch strong and the conditions are only marginal. For experienced surfers, it’s worth a paddle, but don’t expect perfection.

The standout session is without a doubt Sunday morning, 2nd of August. We’ve got a clean 6ft SSE swell rolling in with a 12-second period, and the wind is light and offshore from the WNW at just 6 mph. The energy is moderate (1038), and the forecast says excellent conditions for experienced surfers. This is the one to circle – the waves will be shapely, with good lines off the reef. Keep in mind it’s a consistent spot, so you might see a few others out, but it’s well worth it.

Monday morning, 3rd of August, still has some pulse with a 4ft SSE swell and a clean offshore NW breeze at 12 mph. It’s smaller, but the energy is moderate (323) and it’ll be a fun, clean option for the early birds.

Now, hold on to your board – Tuesday afternoon, 4th of August, sees a massive 15ft S swell with a 13-second period and a massive combined energy of 9784. That’s a very strong, powerful swell. The wind is cross-off from the SW at 19 mph, but the forecast warns the swell is predicted to be too big for this break. This is for experts only, and only then if you know the reef well. It’s going to be a beast, and the rain won’t help.

The rest of the first week sees a mix of decent mornings and messy afternoons. Wednesday, 5th August, has a 8ft SSE swell in the morning but with strong cross-off winds, and Thursday morning, 6th August, is a cleaner option with a 5ft SE swell and offshore WNW wind at 6 mph – that’s a very good call for a Thursday session.

Moving into the second week, the outlook gets more inconsistent. Friday morning, 7th August, has a tiny 2ft SSE swell with a super long 20-second period – that’s a very long-period groundswell, but it’ll be weak energy (431) and only really work on the reef, not the beach. Saturday morning, 8th August, is a better bet: a 4ft SSE swell with a clean offshore NW wind at 9 mph. Good conditions, but not a standout.

From Sunday, 9th August, through to Wednesday, 12th August, the swell size jumps up again – 8ft to 13ft – but the wind turns messy with cross-onshore and onshore breezes, and the forecast is poor. This is a good stretch for kite surfers, not paddle surfers. The energy is strong (up to 6043 on the 11th), but the wind and chop will ruin it for a traditional surfer.

The later part of the second week, from Thursday, 13th August, to Saturday, 15th August, is mostly poor with small, messy swell and cross-shore winds. The energy is low (373 to 270), and the conditions are described as poor. Not worth getting out of bed for.

There’s a light at the end though. Sunday morning, 16th August, brings a promising 4ft SSE swell with a 15-second period and a light cross-offshore breeze from the north at 6 mph. The energy is moderate (784) and the forecast says very good conditions. It’s a long-range call, so less certain, but if it holds, that’s a clean, lined-up session to end the outlook.

Overall, the best of the bunch is Sunday morning, 2nd August – lock it in. The rest is a game of picking the clean windows between the wind and the big stuff.

Rusty.
