The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the pipe for the next couple of weeks.
Right off the bat, we’ve got a lot of energy in the water, but it’s going to take a while for the conditions to line up. For the first few days, the wind is a bit of a mongrel, mostly cross-on or cross, making for lumpy, choppy surf. The water temperature is sitting at 62°, which is pretty much bang on average for this time of year, so no surprises there.
The real standout, the one you want to circle on the calendar, is the morning of Friday the 21st of August at Twilight Beach. It’s looking like a proper session. We’ve got a solid 10ft SSW groundswell pumping in with a very long 16-second period – that’s a lot of energy (3650) and these waves will have some serious push. The wind is swinging out of the NE at just 3 mph, giving us a clean, cross-off breeze. This is a setup for excellent surf, but with that size, it’s strictly for experienced surfers; beginners will want to sit this one out or watch from the sand. The long period will mean nice, well-shaped walls, but be prepared for longer lulls between the sets.
The morning of Saturday the 22nd of August is another solid option. Swell drops a touch to 7ft from the SSW, but the period is still a meaty 14 seconds (2884 energy). The real kicker here is the wind: a gentle 9 mph offshore breeze from the north. That’s going to groom those waves into clean, glassy lines. It’s a great follow-up to the Friday session, and again, it’s one for the experienced crew.
Looking further ahead, there’s a promising window on the 1st of September. The Tuesday morning at Twilight Beach has a 5ft SW groundswell, 15-second period, and a clean cross-off from the NNW. It’s a smaller day, but the quality is expected to be very good. It’s a long way out, so keep an eye on it, but it’s one to have on the radar.
The rest of the forecast is a mixed bag of onshore winds, lumpy conditions, and periods of no real quality. There are a few days where the swell gets big—over 10ft—but the wind is howling, making it a mess. On those days, the setup looks more interesting for kite surfers than for paddle surfing. There’s a lot of poor surf and marginal conditions in between the good windows, so patience is key.
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.
