The Lowdown

G’day, Rusty here. Let’s talk about the surf ahead for Wainui Beach – Stockroute. The next couple of days are a write-off, but there’s a proper pulse building for Sunday and the week after that. The ocean’s a bit colder than normal for this time of year, sitting at 56°, about a degree below the long-term average—so grab a thicker wetsuit if you’ve got one.

We kick off Friday the 31st of July with small, weak energy (190), just 3ft from the ESE at a long 11 seconds. Conditions are clean with a light offshore in the morning, but honestly, it’s tiny and the wave comment nails it: poor surf. Not worth paddling out.

Saturday the 1st of August sees a jump in size, but it’s messy. The morning pushes 7ft from the SSW with a short, jumbly 8-second period and strong cross-off wind at 25 km/h. Energy’s moderate (1104) but the conditions are marginal and the score is low. By the afternoon, it’s 8ft from the SSE with a long 11-second groundswell, but that wind swings cross-shore at 30 km/h and it turns to lumpy chop. This is more interesting for kite surfing than paddle surfing today.

Now, Sunday the 2nd of August is your standout. Morning brings 7ft from the SSE, 12-second period—proper groundswell—and combined energy is solid (1166). The wind is light offshore from the west at just 10 km/h, so it’ll be clean. This is excellent for experienced surfers. That long-period swell will wrap in nicely here at this beach-and-reef setup, giving good shaped waves with longer gaps between sets. Crowds can show up sometimes, so get in early. The afternoon eases a bit to 6ft but stays clean enough with a light south wind.

Monday the 3rd of August drops off to 4ft in the morning from the SE, offshore wind from the WNW at 20 km/h, surfable but nothing special. The afternoon turns glassy with a 3ft SE swell—looks pretty, but small.

Tuesday the 4th of August brings a big pulse: 8ft from the SSE at 15 seconds, massive energy (2997). That’s expert territory; the wind is cross-off and manageable in the afternoon, but the morning is messy with 25 km/h cross-shore wind. Wednesday the 5th and Thursday the 6th hold 6ft to 7ft from the SSE with long periods, but the wind is cross-off and the conditions are just marginal. Thursday morning is better with light offshore from the WNW and 5ft—clean.

The second week is quieter. Friday the 7th is flat and glassy but only 3ft. Saturday the 8th has small 2ft swells but poor conditions. There’s a gap of a few days with nothing worth chasing—Sunday the 9th and Monday the 10th are small and messy. Tuesday the 11th of August has a massive 12ft from the ENE with 11-second period and energy through the roof (3679), but it’s simply too big for this break—only for the absolute hardcore. After that, Wednesday to Friday the 14th offer 4ft to 5ft from the east with long periods and improving winds—Friday morning is glassy and clean, a nice little window if you’re keen. Saturday the 15th fades to 3ft and onshore slop.

Overall, Sunday the 2nd of August is the clear standout—clean, solid groundswell, and that offshore breeze will have the lines holding together. Thursday the 6th morning is a solid backup.

Rusty out.
