The Lowdown
Alright, settle in. Rusty here, and I've got the lowdown on our local stretch. It's a story of a solid, clean swell window that gets slammed shut by a long stretch of choppy, wind-blown junk. You need to be ready to move when the conditions line up.
The first real shot of decent surf is this Thursday, the 20th of August. It's a solid 8ft swell out of the SW, with a very long 16-second period. That's proper groundswell, folks. The morning session is the only call. A light WNW wind, reading as a cross-off, is blowing across the face, keeping it clean. The combined energy is a hefty 3648, so there's plenty of power. This is not for beginners; it's excellent surf for experienced surfers. The afternoon sees the wind swing onshore from the SSW, and the quality goes straight in the bin.
Now, Friday the 21st of August. Early morning, we have a window of pure magic. The swell is still a solid 8ft, shifting to the SSW, with a very long 15-second period. The real story is the wind: a glassy 5 mph easterly. That's as clean as it gets. With the combined energy sitting at 3384, this is the standout session of the entire forecast. The water temp is 61.5°, which is pretty average for this time of year, so no wetsuit drama.
Saturday morning, the 22nd of August, is another solid option. The swell drops slightly to 6.5ft from the SSW, but you get a clean offshore breeze from the north at 9 mph. The combined energy is still a strong 2884. Everything is set for a ripping morning session before the sea breeze ruins it.
After that, it gets messy. From Sunday the 23rd through to the end of the week, it's a write-off. Strong onshore winds, lumpy conditions, and rain. The surf is there, but it's just not worth paddling out for a paddle. You'd be better off looking for a kite.
We do have a small glimmer of hope right at the end of the run. On Sunday, the 30th of August, the morning looks promising. The swell is a smaller 5ft from the SSW, but the period is a very long 18 seconds, and the wind is a light cross-off from the WNW. The combined energy is 1625, and the call is excellent for experienced surfers. It's a long way out, so treat it as a promising possibility rather than a certainty.
The real standout, the one you circle in red, is Friday morning, the 21st of August. Get on it.

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 Twilight Beach 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.
