The Lowdown
Alright, let’s talk Twilight Beach. It’s a spot that’s fairly exposed to the south-west, sitting in an intermediate zone, and it’s fairly consistent. The water temp is around 62°F, pretty average for the time of year.
We’re looking at a slow start. The first half of the week is mostly a write-off. Tuesday morning has clean waves at about 8ft from the SSW, with a fresh cross-off breeze, and the combined energy is strong (2222), but the conditions are just not happening. By Tuesday afternoon, it’s chopped. Wednesday and Thursday see the swell drop to 6ft and then 4ft, and the wind keeps ruining the goods. Thursday morning does offer a clean offshore breeze from the north, but the swell is small—just 4ft with moderate energy (544). Friday morning is the first little window—4ft, tied to a 16-second period, clean offshore wind, and moderate energy (427). It’s tiny but surfable.
Then there’s a few days of messy conditions, but mark Monday the 21st of September on your calendar. That morning, the swell jumps to 8ft from the SSW with a long 15-second period, and the combined energy cranks up to a very strong 2792. The wind is a light, cross-off breeze from the NNE, leaving it glassy. This is the top pick—excellent surf for experienced folks. The long period groundswell will be a bit full-on for beginners though. The afternoons go onshore, so get up early.
On Friday the 25th of September, we see a monster pulse: 18ft of swell from the SSW with a 20-second period, delivering insane energy (24663). It’s way, way too big for this break and the wind is choppy. That’s strictly for the elite crew, and even then it’s sketchy. Same with Saturday morning at 12ft.
The next real standout is Sunday the 27th of September, with 8ft from the SSW, a 15-second period, light cross-off wind from the NNE, and a strong energy reading (2868). Monday the 28th of September is the true king: 10ft, same direction, 16-second period, light offshore breeze from the NNE, and massive energy (8208). That is exceptional, glassy, powerful surf for experts only. The long period (16 seconds) will shape up well on a point or reef, but it might close out on a beachie.
So, to wrap it: the first week is mostly a no-go. The winning windows are Monday the 21st (morning), Sunday the 27th (morning), and the big one on Monday the 28th (morning). That last one is the session to chase if you’ve got the skill. Crowds are sometimes around, so if the forecast holds, expect a few familiar faces in the water. Long-range looks promising but not locked in yet.

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.
