The Lowdown

Hey, Rusty here again, let's talk about Wainui Bay Chalet in feet and Fahrenheit.

First up, the water is sitting at about 55°, which is a bit colder than average for this time of year. You'll be needing a thick suit.

For the first few days, it's pretty flat. Sunday the 30th, we've got tiny 2ft waves from the SSE with a light background wind, combined energy is only 86, real weak. Not much happening.

Monday the 31st is a bit better. The morning shows 2ft from the SSE with a long 17-second period and offshore WNW winds. The energy is up to 275 (moderate). It'll be clean, but that long period might make it break straight. The afternoon has 3ft with a 15-second period and 386 energy. Still small, but clean.

Tuesday the 1st of September is a big one, but heavy. The morning hits 8ft from the S, period 12 seconds, with cross-shore winds. The energy is a massive 3467 (very strong). This is for experts only. Too big and messy for most. The afternoon drops to 6ft, still big, with a cross-offshore wind cleaning it up a bit.

Wednesday the 2nd keeps the size at about 6ft to 6ft from the SSE. The morning has cross-offshore winds and 1589 energy (strong). The afternoon goes glassy with cross-shore wind, energy at 2858 (very strong). Waves are there, but the chop makes it a battle.

Circle Tuesday the 8th of September morning. We've got 6ft from the SSW, a short 8-second period, and 579 energy (moderate). But the wind? Glass. Dead flat calm. It’ll be smooth as a lake. That's a special morning.

Things quieten down again until Sunday the 13th of September. Another monster – 10ft in the morning from the SSW, 10-second period, clean offshore wind. Energy is 2955 (very strong). This is a long-range call, so less certain, but it's for experts only. The afternoon is even bigger at 12ft with 4152 energy, but onshore and messy.

The last days from the 14th are big but blown out with fresh onshore winds.

So the best bet for a clean, fun session is Thursday the 3rd of September. The morning has 4ft from the SSE with a 13-second period and a solid offshore NW breeze at 15 mph. Energy is 409 (moderate). It's clean, has good shape, and isn't too big. The afternoon is the same story, 3ft, still offshore.

If you're an expert, the 1st and the 13th of September are your big, heavy windows, but be ready for serious size and, on the 1st, some messy conditions.

So that's the story: small, clean windows, one perfectly glassy morning, and some huge days for the brave. Rusty, signing off.

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. Our Wainui Bay Chalet surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Wainui Bay Chalet) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
