The Lowdown
Alright, let’s get into it. Rusty here, lookin’ at Trigg Beach for the next couple of weeks.
First up, water temp’s sittin’ at 64°, which is a bit colder than what we’re used to for this time of year – not a shocker, but you’ll be glad for a good wetsuit.
The pattern is a messy one. We’ve got a big pulse of long-period groundswell rollin’ in, but the wind is gonna make life hard for a lot of it. The first real window of decent surf is on Sunday the 9th in the morning. We’ve got a 12 ft swell from the WSW at a very long 16 seconds, and a light cross-shore breeze from the NNW. That’s a lot of juice (combined energy of 6270), but this break can get a bit too straight with that kind of period, and the swell is really pushin’ the limits here – it’s gonna be big and powerful. Only for the experienced crew.
After that, it’s a write-off. Monday the 10th and Tuesday the 11th are blown out or too big, with near gale-force winds and huge, messy swell. Wednesday the 12th and Thursday the 13th are full of onshore wind ripples, making it pretty average.
The standout window is Friday the 14th. Morning brings a clean 8 ft SW groundswell (16 seconds) with a light cross-offshore breeze from the NE. The arvo is even better – glassy conditions from the east, with a clean 8 ft of the same long-period SW swell (combined energy 2594). This is the pick of the fortnight. It’s still a beefy wave for intermediate surfers, but the conditions will be perfect.
Saturday the 15th is another goodie. Morning has a clean 7 ft WSW swell, but the arvo is the real deal – glassy as a mirror from the NE, with a clean 6 ft swell (1433 energy). That’s a beautiful session for a relaxed cruise.
Sunday the 16th morning is also clean with a 8 ft WSW swell, but the wind swings cross-onshore in the arvo and chops it up.
After that, it’s back to the wilderness. From Monday the 17th arvo right through to the end of the forecast on the 22nd, we’re lookin’ at a solid stretch of onshore wind, rain, and generally poor conditions. The swell sticks around, but it’s all cross-on or onshore, with wind speeds hitin’ 18 to 31 mph. There’s a brief window on the 17th morning with a clean 10 ft WSW swell, but the wind is already pickin’ up and it’s a risky call.
Honestly, if you’re gonna paddle out, lock in the 14th and 15th. The 9th is for the brave. The rest of that second week, you’re better off on the couch or the kiteboard.
Catch ya out there.
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.
