The Lowdown
G’day, Rusty here. Let’s break down what’s cookin’ at Twilight Beach for the next couple weeks. Water temp is 62°F, about normal for this time of year – no big anomaly to worry about.
We start Thursday, 10 September, slow out the gate. Morning has a clean 6ft swell from the SSW, 15-second period, combined energy strong (1324), but the tide’s janky. Afternoon drops to 5ft and gets choppy with the wind. Nothin’ to write home about.
Friday, 11 September, morning is the first real highlight. Clear skies, NE breeze at 9 mph, cross-off, clean. Swell’s 5ft from the SSW, but the period is 16 seconds – proper groundswell – and energy is strong (1305). Conditions are very good. This is the one to get out for. Afternoon goes south with cross-on wind.
Saturday, 12 September, morning’s clean but the wind’s fresh from the WNW at 19 mph, cross-off. Swell’s 5ft, 17-second period, energy strong (1179). It’s clean but a battle. Afternoon’s a bust.
Sunday, 13 September, swell holds at 5ft from the SW. Morning’s cross-shore, but afternoon sees a light onshore from the S at 6 mph, energy through the roof (1802). Marginal, but that light wind could smooth it out.
Monday, 14 September, things get serious. Morning swell hits 8ft from the SSW, 14 seconds, energy huge (3118). Wind’s light cross-on from the SE at 6 mph, only small ripples, but 8ft is expert territory. Afternoon’s blown out.
Tuesday, 15 September, solid intermediate day. 7ft SSW swell, 14 seconds, cross-off ENE wind at 12 mph, clean. Energy strong (1960). Big but manageable.
Wednesday, 16 September, the gem. Morning has 6ft SSW swell, 14 seconds, light offshore NNW breeze at 12 mph. Conditions excellent for experienced surfers, clean, energy strong (1455). Afternoon’s just as good with 6ft and a light NE cross-off. Best window of the whole forecast.
Thursday, 17 September, and Friday, 18 September, the swell fades. By Friday afternoon, it’s down to 4ft, energy weak (570). A lull.
Saturday, 19 September, ocean wakes up. Morning swell hits 10ft from the SW, 14 seconds, but wind’s cross-shore from the W at 16 mph. Energy huge (3827). Afternoon onshore. Big, messy, experts only.
Sunday, 20 September, biggest of the lot. 12ft SSW swell, 15 seconds, light cross-on in the morning, but the file says it’s too big for this break. Energy extreme (5510). Leave it for the big-wave crew.
Monday, 21 September, still massive at 10ft to 12ft. Morning has a clean cross-off from the NE. Energy extreme (3436). Expert-only.
Tuesday, 22 September, morning is the next standout. 8ft SSW swell, 14 seconds, light ENE breeze at 6 mph, cross-off. Conditions excellent for experienced surfers. Energy very strong (4237). Big, clean, powerful.
Through to Friday, 25 September, the swell stays big but wind gets messy. Thursday afternoon, 24 September, has a 10ft SSW swell with an 18-second period – very long period groundswell – and a cross-off WNW wind. Energy extreme (5233). That long period will make it break straight at a beach break, but if you’ve got a reef, it’ll be unreal.
Best bets: Friday, 11 September morning, and Wednesday, 16 September all day. First week clean but small, second week huge and powerful. Pick your moment.
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.
