The Lowdown
Alright, grab a coffee and let’s see what’s cookin’ for the next couple of weeks. We’ve only got one spot in the mix here – Wainui Bay Chalet – and it’s a bit of a mixed bag of a forecast. The water is sittin’ at 55°, which is a degree cooler than usual for this time of year, so you’ll wanna stretch that wetsuit if you’ve got a thin one.
Kicking off Thursday 27th August, the morning’s got a clean 3 ft swell from the SSE with a proper long 18-second period, and combined energy is moderate at 673. It’s a light cross-shore breeze, but the forecast calls it marginal – probably a tide issue. By the afternoon, it gets a bit lumpy with an onshore breeze and a 4 ft, 17-second swell, energy jumps to 965, but it’s not clean.
Friday 28th looks better. Morning brings a 4 ft SE swell, 14 seconds, with a clean cross-off breeze from the NNE – that’s rideable. The energy is moderate at 605. Afternoon drops to 3 ft from the SSE, 13 seconds, still clean with a cross-off northerly, energy at 381. It’s surfable but nothing to write home about.
Saturday 29th and Sunday 30th are small. Saturday morning has 2 ft SE, 12 seconds, energy at 142, clean but ordinary. Sunday sees 2 ft from the SE/SSE, periods dropping to 11-12 seconds, energy under 100, but check this – Sunday afternoon is glassy with a light easterly. If you’re desperate for a glide, it’s the best of a weak bunch.
Now hold on – Monday 31st August morning is a standout, but it’s a big one. The swell is 8 ft from the SSW with a short 9-second period, and the energy is strong at 1306. Winds are offshore from the WNW, clean as a whistle. That’s expert territory – too big for beginners, and with that short period and hefty size, it’s gonna be a handful. Only for the brave. The afternoon drops to 6 ft SSE, 13 seconds, energy 1014, but the wind turns onshore, so it’s messy.
Tuesday 1st September is a beast. Morning has 5 ft SSE, 15-second groundswell, energy at 1880 – that’s strong. It’s a cross-shore breeze, a bit of chop, and the forecast says it’s marginal. The afternoon is 7 ft SSE, 14 seconds, energy 1906, but the wind is cross-on, and it’s called too big for this break. Another one for the experts only, and even then, conditions are tricky.
Wednesday 2nd September looks like the pick of the bunch. Both morning and afternoon have 4 ft and 4 ft SSE swells, 12 seconds, with moderate offshore winds from the NW, clean as. Energy is moderate at 528 and 423. This is the sweet spot – clean, manageable size, and a good offshore wind. That’s your best bet.
From Thursday 3rd September onward, it fades fast. Swells drop to 3 ft and below, periods stay around 11-16 seconds, but the energy dips under 200. The winds are offshore most days, so it’s clean, but there’s just not enough push. By the second week, from 4th September to 11th September, we’re looking at 1.0 ft to 2 ft waves, energy mostly under 100, and a few glassy moments but really ordinary surf. A few days have small, clean conditions but it’s more of a splash-around than a proper session.
If you’re keen, hit Wednesday 2nd September for the cleanest, most fun waves. The Monday 31st August morning is a big one for the experts, but approach with caution. The rest of the run is pretty flat and quiet.

Information about the Wainui Bay Chalet Surf forecast
The above surf forecast table for Wainui Bay Chalet provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Wainui Bay Chalet can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Wainui Bay Chalet may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
