The Lowdown
G'day, I'm Rusty. Let's talk surf for Wainui Bay Chalet. It’s a slow start, but there are some proper sessions coming if you’re patient.
Tuesday the 15th of September kicks off with a clean morning. The swell’s a modest 3ft from the SSE with an 11-second period, and the combined energy is a moderate 252. The wind’s a light 3 mph from the north, giving us a nice cross-off breeze. The water temp is about average for the time of year.
The next few days are pretty ordinary, with onshore winds and small swell. Thursday the 17th has a tiny 2ft SE swell at 10 seconds, with a light cross-off wind, but it’s really just a dribbler.
Friday the 18th is a write-off – a fresh 22 mph cross-on breeze from the SSW and messy 3ft swell. That afternoon, a strong 28 mph cross-shore wind and a short, lumpy 6ft swell from the SSE. Not worth paddling out.
Now, Saturday the 19th of September is your first true standout. The morning brings a beautiful 6ft swell from the SSE, but it’s a short 8-second period. The combined energy is a strong 684. The wind is a light 6 mph from the WSW, giving us a clean cross-off breeze. It’ll be clean and fun for an intermediate.
Sunday the 20th has a small 2ft SSE swell at 12 seconds, with a light cross-off breeze in the morning. The energy is 272. Clean, but small.
Monday the 21st of September is the absolute highlight. The morning session is pure magic. We’ve got a 4ft swell from the SSE, a long 12-second period, and a combined energy of 861. The wind is a light 6 mph from the NNW, giving us a clean offshore breeze. It’s glassy, clean, and has enough push for nice lines. The afternoon sees the swell bump to 5ft from the SSE with a very long 17-second period, and the energy jumps to 1408, but the wind turns onshore from the ENE, making it a bit choppy.
The rest of the week gets messy again. Wednesday the 23rd sees a massive 13ft SSW swell, but with a strong 25 mph cross-shore wind, it’s a complete write-off for paddling – this one looks more like a kite session.
Thursday the 24th is a weird one – the swell is 15ft from the south with a 12-second period, and the energy is an enormous 8085. The wind is a fresh 19 mph cross-shore from the SW. The forecast says the swell is too big for this break, and it’s only for experts.
The last week of September sees the swell drop back down. Friday the 25th has a 6ft SE swell at 11 seconds and 1129 energy, but with a cross-shore wind, it’s marginal. Monday the 28th is worth a mention – the morning brings a 7ft S swell with a short 8-second period and 1110 energy, but the wind is a clean offshore from the WNW. The afternoon on the 28th is a glassy 7ft S swell, with light 3 mph NW winds. This is a clean, punchy session for experienced surfers.
Finally, Wednesday the 30th of September sees a nice clean morning with a 4ft SSE swell at a very long 16-second period, a light offshore from the WNW, and 750 energy. Clean and lined up.
So, the best bet is Monday the 21st of September morning for that perfect offshore, clean lines, and solid energy. The second pick is Saturday the 19th of September morning for a fun, clean session.
Rusty.
