The Lowdown
G’day, I’m Rusty, and here’s the outlook for the next 16 days.
Alright, we’ve got one spot on the radar: Twilight Beach. This is a fairly exposed, intermediate-level break that’s fairly consistent. Light winds and a long-period SW groundswell – the kind that brings proper energy – are the main story here. The water temp is about average for the time of year, nothing too wild.
The first real taste of action hits Wednesday morning, August 5th. We’re looking at a clean 7 ft SW swell with a very long 16-second period, pushing through under a light cross-offshore breeze. The combined energy is a strong 2232, and it’s a solid option for experienced surfers. The wind is light, so the faces will be glassy. This is your stand-out session for the early days.
Thursday, August 6th starts with a bigger pulse: 10 ft SW swell, still 16 seconds, and a clean offshore wind from the north blowing at 12 mph. Wave energy is up to 4176. This is strong, powerful surf – definitely for the confident crew. You’ll get some proper groundswell lines. The afternoon cleans up with a cross-shore breeze, but the morning is where it’s at.
Friday, August 7th sees the swell holding around 8 ft, but the wind gets messy with a moderate cross-shore, so quality drops off. Saturday, August 8th is a write-off – near gale-force winds and a huge, blown-out mess. Don’t even think about it.
From Sunday, August 9th through to Wednesday, August 13th, the swell is massive – 13 ft to 26 ft with very high combined energy (20808 on the Sunday morning, 33998 on the Monday afternoon). The wind is often cross-off or favourable, but the wave heights are simply too big for this break. This is expert-only territory, and even then, it’s pushing the limits. The energy is intense, and the sets will be huge with long gaps. For most surfers, this is a time to watch and admire.
Thursday, August 14th brings a turning point. The morning has a clean 12 ft SW swell and a light offshore breeze from the north at 9 mph. The afternoon is even better: 10 ft SW swell, 16 seconds, with a light cross-offshore wind and clean conditions. The energy is a strong 4815. This is a return to excellent surf for experienced paddlers.
Friday, August 15th – the morning is a bit windy with a fresh offshore, but the swell has dropped to 7 ft. The afternoon cleans up nicely with a moderate offshore and 6 ft of SW swell. Expect very good conditions.
Saturday, August 16th – it’s back to big, powerful surf. 12 ft SW swell, but the wind is cross-offshore and clean. It’s still a big wave day, so not for the faint-hearted.
Monday, August 17th is another standout. Both morning and afternoon offer 10 ft SW swell with a long 16 to 17-second period, clean conditions, and excellent surf for experienced surfers. The energy is around 5093 to 5687. Light winds and proper groundswell – this is a gem on the horizon.
Tuesday, August 18th keeps the quality rolling with 8 ft to 10 ft SW swell and clean conditions. Wednesday, August 19th gets a bit lumpy, and Thursday, August 20th finishes the run with a clean 8 ft SW swell and a moderate offshore breeze.
So, the best of the best? Wednesday morning, August 5th for the clean, glassy start with that 7 ft swell, and Monday, August 17th for the pure, powerful groundswell under perfect conditions. Get out there when you can.
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.
