The Lowdown
Alright folks, Rusty here. Let’s size up what’s coming for Twilight Beach.
We’ve got a solid run of swell on the cards, but you’re going to have to work around the wind. The opening weekend is the standout window. Water temp is sitting right on average for this time of year at 61°, nothing out of the ordinary.
Let’s start with Saturday morning, the 15th. This is your best chance. We’ve got a clean 7ft SSW swell rolling in with a 14-second period, giving it proper push and shape. The combined energy is strong (1874), and a light NNE cross-off breeze is going to keep it looking like glass. This will be excellent for experienced surfers – the size is right at that sweet spot for a good session. The swell direction (SSW) isn’t perfect for the optimum SW direction, but the quality of the conditions still makes it the pick of the weekend.
Later Saturday afternoon, the wind swings onshore, chopping things up. Not worth it.
Sunday the 16th is a drop in size and quality. Morning is cleaner with a NE cross-off, but the swell drops to 4ft. The afternoon bumps back up to 6ft with a longer 16-second period, but it’s cross-shore and chopped. You could get a few, but it’s a gamble.
There’s a big gap from here. Monday the 17th through the rest of the week is a mixed bag of strong winds and marginal conditions. Monday morning actually has a fresh offshore wind (NNE at 22 mph) and a punchy 6ft swell with a massive 19-second period from the SSW, but the forecast calls it marginal. That long period will make it wall up and break straight at this beach, so it’s one for the point breaks or reefs elsewhere. The energy is very strong (2573), but the shape will be tricky.
We then hit a dead run from the 18th right through the 20th. Onshore winds, lumpy and choppy seas. Not a wave worth paddling for.
Thursday the 21st sees a solid 10ft SSW groundswell arrive, but the wind is a persistent SE cross-on, making it a messy, bumpy affair with moderate energy (3503-3749). This is too big for beginners and the wind kills it.
Now, Saturday the 22nd is your next real highlight. The morning is looking very promising. A clean, 10ft SSW swell rolls in at 16 seconds, but this time we have a light N offshore breeze at 9 mph. Gentle offshore and clean. The combined energy is strong (3852). This is a big, powerful swell – strictly for experts. The crowd factor can be a thing here, and with quality like this on a Saturday, you can expect some company. Later that day it backs off slightly to 8ft but the wind switches cross-shore.
Sunday the 23rd keeps the size up. The morning is clean with an 8ft SSW swell and a NW cross-off breeze. But the real beast is Sunday afternoon: a massive 10ft SSW groundswell with a 19-second period and a combined energy through the roof (7001). The cross-shore wind will keep a slight chop on the face, but the power is undeniable. Again, expert level only.
From Monday the 24th, the size backs off but the wind turns messy again, with a massive blow-up on the 25th and 26th. On the 25th, we’re looking at a 16ft SW swell with a strong onshore wind. This is pure chaos and dangerous – leave it for the kites or the brave. The energy is very strong (6264).
Finally, we see a light at the end. Friday morning the 28th clears up. A little 5ft SSW swell with a 12-second period under a light NE cross-off. It’s clean, and the combined energy is moderate (1109). It’s a smaller, more manageable day that could produce some fun, clean waves for an intermediate.
The last few days of August and into the 30th are a write-off with strong, messy winds. The swell is still there, but the quality just isn’t.
So, to sum it up: your best chance is Saturday morning the 15th for the best combo of size and clean conditions. Then, if you’re an expert and can handle the power, Saturday morning the 22nd and Sunday afternoon the 23rd are your big-swell targets. Keep the crowds in mind for those.
Stay safe and watch the banks.
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.
