The Lowdown
G’day, Rusty here. Alright, let’s have a proper look at what’s on offer for Twilight Beach over the next couple of weeks.
We’ve got a solid run of swell coming through, but the winds are going to play a big part in whether it’s any good. The water is sitting at about 61°F, which is pretty much bang on average for this time of year, so nothing unusual there.
The standout session is first up – Friday morning, August 21st. It’s glassy, dead calm, with a 8ft SSW groundswell pushing in with a 15-second period. The combined energy is really strong (3384), so there’s plenty of power behind it. This is one for experienced surfers only – it’s going to be a solid, clean, long-period swell, so it’ll be best handling the reef or point setups. Twilight Beach is a fairly exposed spot, so with that SSW direction and glassy conditions, it should be pretty special.
Friday afternoon drops off a bit – the wind swings SE and goes cross-on, making it choppy and marginal. Not worth rushing out for.
Saturday morning, August 22nd, looks like another good one. A clean 7ft SSW swell, 14-second period, with a moderate offshore wind from the north. Combined energy is still strong (2997). It’s still in the expert zone size-wise, but the offshore wind will keep the faces clean. Saturday afternoon turns cross-on again, so aim for the early.
Sunday, August 23rd, is a write-off. Onshore winds, dropping swell quality, and the combined energy falls to 1057. Poor conditions.
We’ve got a bit of a lull then through Monday and Tuesday – the swell hangs around, but the winds are mostly cross-on or cross-off, so it’s just marginal. Not terrible, but not special.
Now, Wednesday morning, August 26th, is another highlight. Offshore wind from the north, 7ft SW swell with a 15-second period, and combined energy of 2565. Clean, powerful, and a good session for the experienced crew. Wednesday afternoon sees the swell jump to 10ft with a 19-second period – that’s a very long period groundswell with massive energy (6402). But it’s onshore, so it’ll be a beast but messy. Probably more interesting for the tow crew or the brave.
Thursday, August 27th, is a mess – strong SW winds, rain, and lumpy conditions. The swell is there but the wind will ruin it. Same for Friday and Saturday – onshore winds and dropping quality.
Then we get a little breather Sunday morning, August 30th. Clear skies, a light cross-off breeze, and a 7ft SSW groundswell with a 16-second period. Combined energy is 2147. Clean and powerful – another good one for experienced surfers.
Monday, August 31st, is also looking promising. Fresh offshore NNW wind, 7ft SSW swell with a 17-second period, and combined energy of 2964. Should be clean and punchy. Monday afternoon stays clean with a cross-off breeze.
Tuesday, September 1st, has a bit of a mix – the morning is cross-shore and a bit lumpy, but the afternoon turns glassy with a 6ft SSW swell. Combined energy is 1255. That’s a smaller, cleaner option for the intermediate crowd.
The rest of the first week of September is a bit of a mixed bag – some clean but smaller swells, and then a big blow on Thursday with strong winds. That Friday, September 4th, though, looks promising again with a 8ft SSW groundswell, 17-second period, and a cross-off wind keeping it clean. Combined energy is 4304 – that’s a lot of power. Early morning will be the pick.
Saturday, September 5th, gets messy again with rain and cross-onshore winds, so that’s a pass.
So, the best on offer is undoubtedly Friday morning, August 21st – glassy, powerful, and clean. The other standout is Wednesday morning, August 26th. If you’re after a cleaner session later on, Monday morning, August 31st, and Friday morning, September 4th, are also worth a look.
Overall, there’s a lot of swell moving through, but the wind is the key. The good windows are there, but you’ve got to time it right.
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.
