The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming down the track for Wainui Bay Chalet.
We’ve got a decent window of swell ahead, and the standout is definitely Sunday the 13th of September. That morning, a solid 5 ft SSE groundswell rolls in with a very long 15-second period, and the wind is a clean cross-off from the west at 9 mph. The energy is pumping at 1175 (moderate to strong), and this break is very consistent and exposed to the SSE direction, which is exactly what it wants. The water temp is about average for this time of year, no drama there. This is the pick of the entire outlook – proper clean, lined-up waves for intermediate surfers. It’s not for beginners though, at 5 ft.
After that, Monday the 14th has a morning session that’s still worth paddling out for. 5 ft SSE swell again, but with a 12-second period. The wind is light from the north at 3 mph, cross-off and clean. The energy has dropped to 773 (moderate), but the conditions are good. Afternoon turns a bit cross-on and choppy, so go early.
Tuesday the 15th morning offers a smaller 3 ft SSE swell, period down to 11 seconds, but it’s clean with a light northerly. Good for a cruise, but nothing to write home about. Afternoon goes messy.
From Wednesday the 16th through Thursday the 17th, surf drops right off to 2 ft. Very weak energy (69-100). Wind is okay in the mornings, but the swell is too small for much fun. There’s a few days here where you’re better off doing something else.
Friday the 18th brings a little pulse back. 4 ft SE swell with a 13-second period in the morning, clean from the northeast. Energy is 436 (moderate). Afternoon turns offshore and stays clean. Not a highlight, but a solid session.
Then we hit a long gap. From the 19th afternoon all the way through to the 24th, the quality is poor, with strong winds, cross-onshore slop, and tiny or junk surf. Saturday the 19th afternoon has 19 mph south-southwest winds – that’s a kite day, not a paddle day.
Now, for the brave: Thursday the 24th of September morning sees a massive 10 ft S swell hit, but the wind is a fresh cross-shore at 19 mph. Energy is huge at 2821 (strong to very strong), but this is only for expert crew, and even then, the wind is messy. That afternoon and Friday the 25th morning, you’ve got 8 ft S swell with glassy conditions – but the swell is still too big for this break, and the short 9-second period means it’ll be crumbly and tough. Not a relaxed paddle-out.
After that, the last few days from the 26th have small clean waves, 2 ft to 3 ft, with very long periods (17-21 seconds) and moderate energy. The wind is offshore at times, so for a longboard or a sunset glide, it’s okay, but nothing epic.
So, overall: Sunday the 13th morning is the absolute stand-out. Monday the 14th morning is your second-best bet. The week after that is mostly flat or too messy, except for the rare big swell day for experts.
Rusty.

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.
