The Lowdown
Right, let’s get the lowdown on Twilight Beach in feet. It’s a proper mixed forecast, and a lot of the early stuff is for the guns only.
We start Monday the 10th with a big, long-period SSW groundswell kicking in at 10ft. The wind is a cross-offshore, so it’ll look clean, but there’s some heavy energy pushing through (3316). The water is sitting about 62°, which is normal for the season.
Tuesday the 11th is a total bust for a normal paddle. That swell is going to blow up to 15ft and 17ft with onshore winds making it a lumpy, awful mess. That’s big-wave gear only, and honestly, it’s more of a kite show than anything else.
Wednesday the 12th and Thursday the 13th are still holding that massive 13ft to 12ft SSW groundswell. The wind is light in the mornings so it looks clean, but the forecast says it’s still too much juice for the break. The energy numbers are wild (6977 on Wednesday morning).
The standout – Friday the 14th. This is the day. Swell is still a solid 10ft from the SSW with a 16-second period, but the wind is the key. It’s glassy offshore from the ENE at only 3 mph. We’re talking clean, powerful lines for the experienced crew. The crowd factor is ‘sometimes’, so you’ll have company but it’s worth it. The energy is strong (4797). This is the pick of the whole run.
Saturday the 15th still has some decent 7ft SSW swell with a clean offshore breeze in the morning. It’s pushy but doable for the intermediate surfer. Sunday the 16th and Monday the 17th see the swell drop and the wind picks up, making it ‘maybe’ territory.
Another solid window is Tuesday the 18th. The swell is a more friendly 7ft to 6ft from the SSW with light winds. Tuesday afternoon is a cracker, with glassy conditions and a light southwesterly breeze. That’s a dream for the experienced guys to get some long, clean walls.
After that, things get messy. A strong WNW blow trashes Wednesday the 19th. There’s a weird spike of short-period 12ft SW swell on Thursday the 20th afternoon, but with a 7-second period, it’s just lumpy, weak junk.
Looking at the second week, a massive, dangerous-looking swell is predicted for Saturday the 22nd of August and Sunday the 23rd. We’re talking 12ft to 13ft SSW groundswell with insane energy (8053). The wind looks clean, but it’s a beast. Experts only. Monday the 24th and Tuesday the 25th see it drop, but the wind is howling, making it a struggle.
To keep it simple: for the best mix of size, power, and absolute perfection, it’s Friday the 14th for the experienced surfer. For a slightly smaller but still excellent, glassy session, lock in Tuesday the 18th afternoon. The rest is either too big, too windy, or just plain average.

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.
