The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the menu for Trigg Beach.

We’ve got a decent stretch of surf on the way, but you’ll need to pick your moments. The good news is, the first few days are looking clean. The water’s sitting at 64°, which is a bit colder than normal for this time of year, so you might want that extra layer.

Thursday 13th kicks off with a ripper of a morning. There’s a solid 7ft SW groundswell with a long 16-second period, and it’s carrying some serious energy (2299). The wind is light and offshore from the ENE, so Trigg should be clean and lined up. This is for experienced surfers at that size, but it’s a standout window. The afternoon turns a bit messy as the wind swings onshore, so make the most of the early session.

Friday 14th is another good one. The swell drops back a touch to 7ft, but still that long-period SW groundswell, and both morning and afternoon are clean with light offshore or cross-off breezes. Consistency is good, and the energy is still pumping (2413 and 2233). This is your best run of the week.

Saturday 15th sees the swell easing to 6ft and the period dropping to 14 seconds. The morning is clean with a NNE breeze, but the afternoon gets a light cross-onshore, so not as crisp. Still a fun size for a paddle.

Sunday 16th bumps back up to 7ft with a 16-second swell in the morning, but the wind is a moderate offshore – clean enough. The afternoon is a bit junky with cross-onshore wind.

Now, from Monday 17th through to Thursday 21st, it’s pretty grim. The winds get strong and onshore, and the swell jumps up to 10ft and bigger. Tuesday 18th actually has a huge 13ft swell and glassy offshore wind, but it’s simply too big for Trigg Beach – that’s expert-only and likely maxed out. Wednesday 19th brings a risk of thunderstorms and 45 km/h winds. Not for paddling. This is a long stretch of poor conditions, about five days of mostly unsurfable, messy, or dangerous surf.

Things start to settle again from Friday 22nd into the weekend, but the wind stays cross-onshore and the swell is still solid at around 8ft to 10ft. It’s marginal at best.

Monday 24th is more of the same – clean enough but cross-onshore. The real standout pops up on Tuesday 25th. The morning is glassy. Dead flat. The swell is a chunky 10ft from the WSW with a 16-second period and very strong energy (4938). For those who can handle it, this is a gem – clean, powerful, and long-period groundswell. The afternoon gets a cross-shore, but the morning is the pick of the second week.

Wednesday 26th is a nice little reset with a 7ft swell and light offshore wind – great for a more relaxed session. Then Thursday 27th drops right off to 3ft and the wind turns onshore, so the fun is pretty much over.

Friday 28th looks nasty with rain showers and a 15ft swell under strong onshore wind – that’s a hard pass.

Overall, the best surf of the whole outlook is Thursday 13th and Friday 14th mornings, and for those with skill, the glassy morning of Tuesday 25th is well worth a look.

Rusty.

Information about the Trigg Beach Surf forecast

The above surf forecast table for Trigg Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trigg Beach can be found by selecting the local surf guide option on the grey menu. Our Trigg 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 (Trigg 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 Trigg 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.
