The Lowdown
Imperial Version
G’day, Rusty here.
Alright, so we’ve got a bit of a mixed bag coming our way at Twilight Beach. This spot is fairly exposed to the southwest, so it’s going to be picking up most of the action over the next 16 days. The water temperature is sitting around 62°, which is pretty much what you’d expect for this time of year.
We’ve got a long stretch of poor to marginal conditions kicking things off. The surf is there, but the winds are going to mess it up for a few days. Wednesday and Thursday are a write-off with strong cross-shore winds and lumpy, choppy surf. Friday and the weekend aren’t much better, with that SW to W wind making a mess of things. Nothing worth paddling out for.
Now, hold onto your board, because Tuesday, September 15th, is your standout. We get a lovely 7ft SSW groundswell with a 15-second period, and the wind swings offshore from the north at 9 mph. That means clean, groomed waves. This is a solid intermediate-level swell, and it’s going to be firing. The combined energy is strong (2042), and with that offshore wind, it’s the best session of the whole run.
Monday, September 14th is also worth a look – we’ve got a bigger 8ft SSW swell (2734 combined energy) in the morning, and the wind is only a light cross-on. It’s not perfect, but the size and period (14 seconds) make it a decent option for those comfortable in bigger surf.
After that, things get a bit sketchy again. We’ve got a gap of a few days with poor or onshore conditions, before another promising window opens up. On Friday, September 19th, a new 8ft swell (1414 combined energy) rolls in, but it’s short period at 8 seconds. The offshore wind from the northwest in the morning could clean it up, though. That swell builds to a massive 10ft by the afternoon, but then the wind turns onshore.
Now, look ahead to Tuesday, September 22nd. The forecast is showing a huge 18ft SSW swell (33231 combined energy) – that’s very strong energy. But, the comment says it’s predicted to be too big for this break. That’s expert territory only, and only if the wind plays ball. It’s something to keep an eye on, but it’s a long way out and things can change.
Overall, set your alarm for Tuesday the 15th. That’s the one to chase.
Rusty.

Information about the Twilight Beach Surf forecast
The above surf forecast table for Twilight Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Twilight Beach can be found by selecting the local surf guide option on the grey menu. Our Twilight Beach 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 (Twilight Beach) 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 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. 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.
