The Lowdown

Alright, folks, Rusty here. Let’s break down what’s happening at Twilight Beach.

We’ve got a solid run of groundswell coming through, mostly from the SSW and SW, with periods hanging around 14 to 18 seconds. That’s proper long-period energy, meaning better shaped waves but longer waits between sets. The water is sitting at 62°, which is just about average for the time of year, so no surprises there.

The first real chance to get wet starts Monday the 17th with a fresh 22 mph offshore breeze from the NNW. The swell is 6ft from the SSW with an 18-second period, and the combined energy is a hefty 1944 – that’s strong, powerful stuff. The wind is offshore, so conditions will be clean, but that size and period will have some punch. For the intermediate crew, it’s doable, but take it serious.

Tuesday the 18th is a bit of a washout in the morning with a cross-on wind, but the afternoon settles. Light wind at 6 mph, 6ft SSW swell, still 16 seconds. It’s cross-shore, so a little bumpy, but not a total loss. Wednesday the 19th shapes up nicely, especially the afternoon. A light 3 mph onshore wind from the south, 7ft SW swell, 16 seconds – the combined energy is 2146. It’s clean, punchy, and the direction is right on the optimum SW. That afternoon session on Wednesday is the pick of the first week.

Thursday the 20th gets bigger – 8ft SW swell, but the wind is a bit messy. Friday the 21st is the standout for the early run. Morning light cross-off breeze, 8ft SSW swell at 15 seconds, and the energy is 3284. The forecast says excellent for experienced surfers, and I’d agree. That’s proper, groundswell power, clean and solid. Saturday the 22nd morning is also a gem with a gentle offshore from the NNE, 7ft SSW swell, and 2834 energy. Clean waves for the intermediate and above.

After that, things get a bit lumpy and a lot bigger. Sunday the 23rd has some rain and onshore wind, and from the 24th onwards, the swell starts to push over 8ft and up to 12ft. By Tuesday the 25th, we’re looking at 10ft to 12ft SW swell with cross-on wind. That’s expert-only territory, and honestly, with the wind angle, it might be more of a kite-surfing show than a paddle session. The energy numbers are massive – 4996 and 4409 – but the quality drops off fast.

The second week has a couple of redeeming moments. Friday the 28th morning (that’s a week and a half away) has a light cross-off wind, 10ft SSW swell at 15 seconds, and 3348 energy. Clean and powerful. Then Saturday the 29th morning kicks off with a moderate offshore from the north, 7ft SSW swell, 16 seconds, and 1943 energy. That’s a nice, clean, long-period option. The 30th also has a clean morning with a 6ft SW swell but a very long 20-second period – that’s groundswell gold, but it’ll be breaking straight at the beach, so look for a bend or a reef to make the most of it.

Overall, the best on offer is Wednesday the 19th afternoon and Friday the 21st morning. Two standouts that are clean, punchy, and have the right wind and swell direction. After that, it’s a game of picking the clean windows in between the big, lumpy stuff.

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.
