The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for our stretch of coast. We’re only looking at one spot today: Twilight Beach.
Right off the bat, the first few days are a write-off. Tuesday the 11th is a total mess – we’ve got a massive 15ft SSW swell, but it’s coming in with a 22 mph cross-onshore wind. The water temp is sitting at about 62°F, which is normal for this time of year, but the conditions are just lumpy and poor. Not worth paddling out. This big swell energy is strong, reading over 15,000, but completely wasted.
The next couple of days, Wednesday the 12th through Thursday the 13th, the swell is still huge – between 13ft and 12ft. The guidance says the swell is just too big for this break. Even though Thursday morning sees a light WNW offshore and glassy conditions, these waves are over 8ft, so that’s expert territory only. The energy is still high, dropping from the 7,000s to the 5,700s.
Now, Friday the 14th morning is where things start to get interesting. That’s the standout in the near term. We’ve got a clean 10ft SSW swell with a nice 16-second period and a light NE cross-offshore breeze. The water is clean. This is solid, punchy groundswell for experienced surfers. The combined swell energy is still a respectable 4,724, and the offshore wind means good shape. This is your best bet in the first week, but it’s big, so leave the foamies at home.
Saturday the 15th drops down to 7ft in the morning with clean conditions and a cross-off breeze, but the rating is marginal. Sunday the 16th is smaller again – around 4ft to 6ft – and just not exciting.
There’s a gap of a few days of mediocre surf until we hit Monday the 17th afternoon. That session stands out: 7ft SSW swell at a very long 18-second period, with a light NNE cross-offshore breeze. The energy is moderate at 2,444, but the period is excellent. Long period groundswell like this can be a bit straight for beach breaks, but with offshore winds, the lineup should have some nice, lined-up sets with good gaps between them.
After that, we go through a bit of a lull with smaller, choppy, or onshore conditions straight through to Saturday the 22nd. Nothing to get excited about, just small waves and less than ideal winds.
Hold on though – the real sleeper is Sunday the 23rd. Look at this: glassy conditions all day. In the morning, only 3ft but with a very long 17-second period and glassy wind. The afternoon is a beauty – 4ft SSW swell at a whopping 20-second period, glassy calm. The swell energy is 2,500, which is moderate but the period is exceptional. This is a true long-period groundswell. It’ll wrap in nicely, and with glass, it’s going to be some of the cleanest, most user-friendly surf of the whole forecast. Might be a little inconsistent between sets, but the quality will be top-notch. Beginners could handle this.
Then Monday the 24th brings a big jump: 8ft SSW at 17 seconds with light offshore winds. The energy is strong at 4,425. This one is for the experienced crew again, but it’s clean and powerful.
The last few days of the 16-day window show strong winds and messy conditions, so don’t plan around Tuesday the 26th.
So, the top picks: Friday 14th morning for the experienced surfer looking for power and clean conditions, and Sunday 23rd afternoon for the absolute glassy, long-period gem that could treat everyone.
Stay 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.
