The Lowdown

G’day, Rusty here. We’ve got a solid 16-day window of surf on offer at Wainui Bay Chalet, starting Friday 21st August. The water is runnin’ about 55.4°, which is a bit colder than normal for this time of year, so you’ll want a decent wetsuit.

The week kicks off with a clean, small pulse Friday morning. Swell’s from the SSE at 2.0ft with a long 16-second period, bringin’ in moderate wave energy (460). That NW wind is blowin’ light offshore, so the lines will be clean and tidy. Crowds are sometimes a factor here, so you might have a few mates out, but it’s a good time to be in the water. Friday afternoon sees the swell bump up to 3.6ft, but the wind swings cross-on from the ENE, messin’ up the face a bit – still surfable, but not as good as the morning.

Saturday morning, 22nd August, is a ripper. Swell holds at 3.0ft from the SSE, with a moderate 12-second period and moderate energy (264). The wind’s a solid 12 mph from the NW, blowin’ offshore and clean. This is a standout for the weekend – crisp, clean lines, and the swell is just right for intermediates. Saturday afternoon stays clean with a light WNW offshore, though the swell drops a touch to 2.6ft.

Sunday 23rd August is smaller and weaker. The morning has 1.6ft from the SE with an 11-second period, and the NW wind is offshore but moderate at 16 mph. The energy is weak (93). It’s surfable, but ordinary. Afternoon drops to 1.0ft from the ESE. You’d be better off waiting.

Monday 24th August is a mixed bag. Morning has 2.0ft from the SSE (9-second period, 84 energy) with a cross-off WSW wind – clean, but small. Afternoon pushes 2.6ft from the SSE with a 16-second period, but the onshore SE wind kills it. Ticklish conditions.

Tuesday 25th August morning is a beauty. Swell’s 3.3ft from the SSE, 12-second period, moderate energy (276), and a light WNW cross-off breeze. Clean lines, good shape. This is the best of the early week. Afternoon goes cross-on from the ENE, so get out early.

Wednesday 26th August is small again. Morning has 1.6ft from the SSE (15-second period, 174 energy) with a moderate WNW offshore – clean but tiny. Afternoon picks up a 1.6ft S swell at a very long 17 seconds, with a light NW offshore. That long period means the waves will have more energy and better shape, but at this size, it’s a mellow session.

Thursday 27th August morning is similar: 2.0ft from the SSE, 15-second period, clean with a light WNW offshore. Afternoon swells to 3.0ft from the SSE, but the ESE cross-on wind makes it marginal.

Now, Friday 28th August morning is the standout of the whole forecast. Swell builds to 3.9ft from the SSE with a 14-second period, and the combined energy is solid (581). The wind is a light NNW cross-off, so the waves will be clean and well-shaped. This is the best size and quality of the run – a true gem for intermediates. Crowds are sometimes a thing, but with these conditions, it’s worth the company. Afternoon holds 3.3ft from the SSE, still clean with a N cross-off.

Saturday 29th August is a write-off for the morning – strong NNE wind at 19 mph, cross-off but messy, and the swell is 2.3ft with poor energy. Afternoon has a lighter N wind, but the swell is still small and ordinary.

The next week runs pretty quiet. Sunday 30th August has a tiny 1.3ft from the SSE, weak energy (56), and a moderate NW offshore. The swell drops to 1.3ft from the SE on Monday 31st August, but Monday morning is glassy – 2.6ft from the S with a 5-second period, and zero wind. That short period means it’s sloppy, but the glassy surface is a moment of calm. Afternoon turns onshore.

Tuesday 1st September morning brings a 3.0ft SSE swell at 14 seconds, with a light N cross-off – clean. Not massive, but a decent session. The rest of the week is a mix of poor conditions and onshores, until Wednesday 2nd September afternoon, which fires up with 3.3ft from the SSE, 16-second period, and a light NNW offshore. That’s a solid, clean late-afternoon option.

Thursday 3rd September sees a bump in size to 5.2ft from the S, but with a 7-second period and strong cross-shore wind, it’s choppy and messy. That’s more for kite surfing than paddling. Friday 4th September is similar: 3.6ft from the SSE but cross-shore winds, poor

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.
