The Lowdown
Alright, mate, Rusty here. Let’s get into it.
We’ve got a solid run of south-west groundswell on the cards for Twilight Beach. The water is sitting at 62°F, which is pretty much normal for this time of year, so nothing out of the ordinary there.
The first good window hits Thursday morning, the 20th of August. There’s a strong 8ft SW groundswell rolling in with a long 16-second period, packing moderate to strong wave energy (3648). The wind is a light north-westerly, so it’s cross-off, and conditions are clean. This is excellent for experienced surfers – the swell is a bit too big for beginners. The crew factor is something to keep in mind, as crowds are sometimes an issue here.
Friday morning, the 21st, is a real standout. The swell is still 8ft from the SSW, with a 15-second period, and the wind is glassy – a light north-easterly. That’s magic. The wave energy is strong (3384), and you’ll be looking at clean, lined-up sets. Again, this is for the experienced crew.
Saturday morning, the 22nd, also looks good. There’s a 7ft SSW swell, 14-second period, with a moderate north wind blowing offshore, keeping things clean. The energy is strong (2906). Another excellent session for the more confident surfers.
Sunday the 23rd and Monday the 24th are a write-off, with messy winds and poor conditions. Tuesday the 25th is a small day, with 5ft swell and low energy, so not worth getting excited about.
Then we get another pulse on Wednesday the 26th of August. The morning has a 10ft SW swell with a 15-second period, and a light west-north-west wind, so it’s cross-off and clean. The energy is strong (3869). This is for the experts only – 10ft is serious size. The afternoon turns onshore, so morning is the call.
The end of August and the start of September gets messy. Strong winds and rain spoil the surf from the 27th through the 30th. There’s a big lull with no real quality.
But hold on – Monday the 31st of August morning is a hidden gem. A 6ft SW swell, 16-second period, with a light west-north-west breeze, cross-off and clean. The energy is moderate (1651). This is much more manageable and still a great session.
The 1st of September Tuesday morning has a 12ft SW swell, but it’s flagged as too big for this break, so give it a miss.
The 2nd of September Wednesday morning is a good one. A 7ft SW swell, 14-second period, with a moderate north-north-west wind blowing offshore, keeping it clean. The energy is moderate (1522). That’s excellent for experienced surfers.
The 3rd and 4th of September are a mixed bag, with some possible windows but tricky winds.
Overall, the standout sessions are Friday morning, the 21st of August, and Wednesday morning, the 26th of August, for the bigger, more powerful swells. If you want something a bit more manageable, Monday morning, the 31st of August, is your pick. Stay sharp, and get out there when it’s clean.
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.
