The Lowdown

G’day, Rusty here. Let’s get straight into the forecast for Wainui Beach - Stockroute. This is an advanced, very consistent beach and reef setup that’s exposed to the swell, so when it’s on, it’s on. The water temp is sitting at 55.6°, which is a bit colder than normal for this time of year – you’ll want a decent hood and gloves.

The first real surf comes Tuesday afternoon, 28 July, with a 6.6ft ESE swell at 13 seconds. That’s a solid groundswell, but the wind is a cross-shore from the SSW at 12 mph, and the combined energy is pumping at 1649 (moderate to strong). The conditions are marginal – that cross-chop will make it tricky, so it’s not a standout.

Wednesday morning, 29 July, is where it starts to get interesting. We’ve got a 5.6ft ESE swell, 13 seconds, and the wind swings to the WNW at just 6 mph, blowing straight offshore. That’s clean as a whistle. The combined energy is 877 (moderate), and the waves will be well-shaped for a point break or reef. This is a real highlight – the offshore wind makes it glassy, and the swell direction is a close match to the optimum SSE. It’s a good call for experienced surfers. Wednesday afternoon sees the wind shift to a cross-on NE breeze at 9 mph, so the quality drops off.

Thursday morning, 30 July, is another beauty. The swell drops to 4.3ft from the ESE at 12 seconds, but the wind is a cross-off NNW breeze at 9 mph, keeping it clean. Combined energy is 509 (moderate). It’s a nice, manageable size for a fun session. Thursday afternoon gets smaller at 3.6ft, still clean but marginal.

Friday, 31 July, the swell drops right off to under 3.3ft – poor conditions, not worth paddling out. You’ll want to sit this one out.

Saturday, 1 August, brings a new swell – 6.9ft from the SSW at 8 seconds. That’s a short-period windswell, and the wind is a cross-off from the SW at 12 mph, so it’s clean but the energy is 748 (moderate). The short period means it won’t have much shape, so it’s marginal. Saturday afternoon gets nasty – 9.8ft from the SSW at 10 seconds, but the wind goes to 22 mph from the SSW, making it a fresh cross-shore mess. That’s for kite surfers, not paddle surfers.

Sunday, 2 August, is a big one – 11.5ft from the S at 11 seconds, with a cross-off SW wind at 22 mph. The combined energy is 4252 (strong), but the swell is too big for this break – it’s only for experts, and even then, it’s on the edge. Sunday afternoon is a write-off with 28 mph winds and rain.

Monday, 3 August, drops back to 4.9ft from the SE at 10 seconds, with a light cross-off WSW wind at 9 mph. It’s clean, but the energy is low at 446 – marginal.

Tuesday, 4 August, is another giant day – 13.1ft from the S at 12 seconds, with a fresh cross-shore from the SSW at 22 mph. That’s a massive 5979 energy, but it’s too big and messy. Tuesday afternoon sees 13.1ft at 14 seconds, energy at 10692 (very strong), but again, it’s too big for the break – only for the brave.

Now, Wednesday morning, 5 August, is the real standout of the whole forecast. The swell drops to 6.9ft from the SSE at 14 seconds – that’s a long-period groundswell, perfect for this setup. The wind is a glassy offshore from the WNW at just 3 mph, making it as clean as it gets. The combined energy is 1565 (moderate to strong), and the swell direction matches the optimum SSE. This is excellent for experienced surfers – a true gem. Wednesday afternoon the wind goes cross-on, so the window is tight.

The rest of the week from Thursday, 6 August, to Sunday, 9 August, is a mix of onshore winds, big lumpy swells, and rain. There’s nothing worth chasing there – the conditions are poor, with cross-shore winds and chop.

Monday, 10 August, and Tuesday, 11 August, are small and weak – under 3.3ft with poor wind. Not worth it.

Wednesday, 12 August, sees a small 3.9ft E swell at 11 seconds, with a light offshore NW wind at 6 mph. That’s clean and glassy, with energy at 345 (weak to moderate). It’s a fun little session for a longboard, but not a standout.

So, to wrap it up: the best surf on offer is Wednesday morning, 29 July, with offshore winds and a solid 5.6ft groundswell, and Wednesday morning, 5 August, with a glassy 6.9ft groundswell matching the optimum direction. The 5 August window is the pick of
