The Lowdown
Right, folks, Rusty here. Let’s have a look at what this 16-day stretch has got cookin’ across these parts.
Alright, we’re looking at a period that starts a bit slow, but builds into some serious, solid groundswell that’ll get the blood pumping. The water here is sitting at 57°, which is a bit colder than we usually expect this time of year – so don't forget the booties. The opening days are a warm-up, but the real show starts from Friday the 11th onwards.
Today, Wednesday the 9th, the swell is small. You’ve got a clean 3ft from the WSW (13 seconds) with a cross-off wind. It’s a light one for the experts only; the combo energy is weak right now (340). Not a standout.
Thursday the 10th sees a big jump. The swell bumps up to 8ft from the WSW (14 seconds), and by the afternoon, the wind picks up. The combined energy is ramping up (2346), but with cloudy skies and a cross-off wind, it’s still not top-tier. It’s big and powerful.
Now, Friday the 11th is where we start to see the quality. The swell sits at 6ft from the WSW, period stretching to a nice 12 seconds, and the wind goes offshore and clean. This is moderate offshore wind and the energy is solid (1287). This is getting good for experienced surfers.
But the absolute standout is Saturday the 12th. This is it. We’ve got a pumping 8ft swell from the SW, with a very long period of 17 seconds. The combined energy is ripping at a massive 4441 – that’s serious, powerful groundswell. The wind is offshore at 25 km/h, keeping everything clean and lined up. This is a classic, powerful reef-break day. For the advanced crew, this is your session. Because of that very long period, the sets will be solid and well-defined, making the paddle-out a bit easier between bombs, but it’ll be big. It’s definitely not a beginner wave at 8ft.
Sunday the 13th drops off a bit, with a cross-on wind and 7ft SW swell. The energy is still there (1563), but the quality takes a hit. Things get poor through Monday and Tuesday the 14th-15th as a strong cross-onshore wind messes it up, with a 3ft to 6ft swell.
Look ahead to Wednesday the 16th – we get a massive spike. It’s 13ft from the SW (14 seconds) with a cross-off wind. The energy is insane (6415). This is for experts only, and even then, it might be too much. The wind is clean, but at that size, it's a beast.
Later in the week, Thursday the 17th has strong offshore winds (up to 31 mph) which will clean the 6ft swell up, but wind that strong makes paddling in a nightmare. By Friday the 18th, however, things settle right down. The morning looks beautiful with a light offshore breeze and a clean 4ft SW swell (633 energy). That’s a lovely, clean session for the experienced surfer.
The second week stays active. The 21st of September Monday afternoon brings an excellent 8ft swell from the SE with a 10-second period and offshore wind (2822 energy) – punchy and clean.
Finally, the real hidden gem of the whole forecast is Thursday the 24th of September. The morning is glassy. Wind is 0 km/h from the WSW. The swell is a clean 4ft from the SW with a very long and tasty 16-second period (947 energy). That is a dream window. The waves will be perfect, lined up, and clean as a whistle. Then the afternoon picks up to 5ft with a period of 15 seconds and a light cross-off breeze for more excellent conditions. This is the pick of the later period.
So, in short: Saturday the 12th for power and size, and Thursday the 24th for absolute perfection.
Rusty out.
