The Lowdown

Alright, Rusty here, let’s break down what’s on the menu at Wainui Beach. The next couple of weeks are a real mixed bag – some incredible, clean, powerful swells for the experts, but also some long stretches of pure slop.

We start on Wednesday, 29th July. The morning is the pick of the early window. Wainui Beach - Stockroute will be pumping with 1.7m of clean, lined-up surf from the ESE. The wind is a light offshore out of the WNW, which is a dream for this spot. The water is sitting at 13°, which is a bit colder than what we’d normally expect for this time of year – a solid 1° chillier, so bring the thick wetsuit. The combined energy is moderate at 877, and with a 13-second period, there’s plenty of punch. This is a solid session for the advanced crew, and the crowds are only *sometimes* an issue, so you’ve got a decent shot at a few solo waves.

Thursday morning, 30th July, is another clean one with a lighter 1.3m from the ESE and a light cross-offshore breeze. The energy drops a bit (509), but it’s still a fun, clean surf. The afternoon sees the swell drop further and the wind picks up, so it’s a morning mission.

Saturday morning, 1st August, the swell swings to the SSW at 1.4m with a 9-second period and light cross-offshore wind. The combined energy is moderate (589), and it’s clean. But be warned, Saturday afternoon gets windy, and the swell jumps to 2.5m, getting a bit too messy.

Now, here’s the big one. Sunday morning, 2nd August, we’ve got a massive 3.5m swell from the south with a 10-second period, but the wind is a 35 km/h cross-offshore. The combined energy is huge at 4456, but the swell is just too big for this break, even for the experienced. The afternoon is a total write-off with strong cross-shore winds.

Monday, 3rd August, offers a redemption window. The afternoon is absolutely glassy – zero wind, with a 2.2m swell from the south (11-second period, 1592 energy). That’s excellent surf for experienced surfers, clean and powerful.

Tuesday, 4th August, is the one to circle on the calendar. The morning is a true beauty: 3.0m of groundswell from the SSE with a *very long* 16-second period, light offshore wind, and a combined energy of 4885. This is expert-only territory, and it will be a standout. The long period means it’ll be grinding perfectly at this point break and reef setup, with long lulls between sets making the paddle out easier. The afternoon gets a bit cross-onshore, so be on it early.

Wednesday, 5th August, morning is another cracker for the experienced: 2.5m from the SSE, 14-second period, light cross-offshore wind, and 3091 energy. The month of August is shaping up to have some savage, clean, powerful swells.

From Thursday, 6th August, the swell drops a touch to the 2.0m to 2.5m range, still clean in the mornings, but the wind turns more cross-onshore in the afternoons.

The second week, from Friday, 7th August, through to Wednesday, 13th August, turns ugly. The wind goes onshore and strong, the swell stays messy and lumpy, and the conditions are poor. There’s a solid 8-day stretch of no-good surf here, with onshore winds and lumpy cross-chop making it a write-off. The only flicker of hope is a very small clean-up on Thursday, 13th August, with a 1.9m ESE swell and light cross-onshore wind, but it’s marginal.

So, the call is simple: Wednesday morning, 29th July and Tuesday morning, 4th August, are your true standouts. The 4th is the big one – that massive, long-period groundswell with offshore wind is the session of the forecast. Thursday morning, 5th August, is also top-tier.

Stay safe out there.
Rusty.
