The Lowdown
Alright, Rusty here, let's talk about what's shaping up at Twilight Beach. We've got a mixed bag, but a couple of days are gonna be worth the paddle out.
Water temps are bang on average for this time of year at 62°, nothing unusual there. Mostly, we’re looking at a strong, long-period SSW groundswell (16 seconds) pumping through, which brings real energy. We're talking moderate to strong wave energy all week, with the combined energy values sitting between 1,661 and 3,777 for the first few days.
Wednesday the 19th has some clean morning surf with a 7ft SW swell and a cross-offshore wind, but the real standout kicks off Thursday morning the 20th. It’s a bit of a beast – 8ft of SW groundswell with a light WNW breeze keeping it clean. That’s excellent for experienced surfers, but if you’re a beginner, this one’s gonna be too hefty. The wind stays light and clean, making for some proper waves.
Then, get this – Friday morning the 21st. The wind drops to glassy, completely dead calm, and the swell jumps to a solid 10ft from the SSW, still with that long 16-second period. This is the pick of the bunch for the whole outlook. Big, clean, and powerful. Experts only for sure, over 8ft, but it’s gonna be a special session if you’re up for it.
Saturday morning the 22nd stays good with a 7ft SSW swell and a clean offshore from the north, though not quite as big or glassy as Friday.
Sunday the 23rd turns ugly. Strong onshore wind and lumpy conditions wreck the surf. We’ve got a few days of this, but then we’re heading into some solid but tricky conditions.
Monday the 24th sees a beautiful glassy start with the swell back to 7ft, but the crowd factor is worth a mention here – it can get busy sometimes, so get in early.
Around Tuesday the 25th, the wind ramps up big time, with fresh westerlies. The swell spikes hard to 10ft on Tuesday afternoon, but it's messy and cross-offshore. By Wednesday the 26th, it’s a full-on, strong cross-onshore mess with a 13ft swell and total wave energy hitting 11,938. That's a real code red for paddling – looks more like a kite-surfing setup unless you’re a proper charger in massive, ugly conditions.
Thursday the 27th, the swell is still massive at 12ft, but the wind is light and cross-shore. The guide notes the swell is just too big for the break, even if the wind is decent.
We get a bit of a breather from the 28th to the 30th, with surf dropping to a more manageable 5ft to 8ft, but winds are mostly cross or cross-on, so nothing to get worked up over.
Looking deep, we get a couple more windows: Saturday the 29th morning is clean with a 5ft SSW swell and a light offshore from the NNE, and Monday the 31st morning is back to glassy perfection with a 6ft SSW swell. A solid, clean option for intermediates as well.
Finally, into September, Tuesday the 1st and Wednesday the 2nd both have clean, offshore mornings, with 5ft and 7ft swells respectively. The 2nd is the better of the two for power, but both are well worth a look.
So for the bold, Friday the 21st of August is your big, glassy, stand-out session. For cleaner, more manageable waves, target the mornings on Thursday the 20th, Monday the 24th, or Monday the 31st.
Keep it salty.
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.
