The Lowdown
G’day, Rusty here. Let’s cut to it. The next couple weeks at Trigg are a proper mixed bag. We’ve got the swell, but the wind and the size will be calling the shots. This ain’t a simple “go out and score” stretch. You’ve got to pick your moments.
The first few days are a total right-off. Saturday the 8th is blown out – a near gale cross-onshore with 16ft of swell. That’s not surf, that’s chaos. Sunday the 9th cleans up a touch, but that 12ft+ is still too much for this break, and the onshore wind is messing it up. Monday the 10th is back to poor and blown out. So we’re looking at a few days of nothing worth paddling for.
The real window opens Tuesday the 11th. Tuesday morning we’ve got some clouds, a glassy 13ft WSW swell (combined energy 9212) and a light ENE breeze. That’s a ton of water, and with a 16-second period, it’s got serious push. This is only for the experienced crew – 13ft is no joke. Big, but if you know what you’re doing, Tuesday morning is your first real shot.
Wednesday the 12th is where it gets exciting. Morning brings a drop to 8ft, glassy conditions, and that same long-period WSW swell (energy 3000). This is the standout of the first week. Clean, glassy, and a proper size for Trigg. It’s the kind of morning you don’t want to sleep through. Swell direction is right, no wind – the lines will be holding up beautifully. This is your pick of the week.
Thursday and Friday (13th and 14th) are solid too. Swell drops to around 7ft, still clean and glassy or with a light offshore. Excellent conditions for the experienced surfer. These will be fun, cruisy days, but the energy is a bit lower. Wednesday still has that extra punch.
The weekend of the 15th and 16th is more marginal. Smaller swell, around 6ft, and the winds get a bit tricky with a cross-off in the morning. It’s surfable, but not the same quality as mid-week. You could grab some fun ones if you’re patient.
Then, the second week. Monday the 17th sees a new pulse – 10ft with an 18-second period, but it’s a cross-shore wind. Still, that long period could make it interesting for the better surfers. But Monday afternoon jumps back up to 13ft, and Tuesday the 18th is blown out again. A bit of a mess.
The real standout of the second week is Wednesday the 19th. We’re looking at a huge 16ft WSW swell (energy 13110) with a light NE cross-off wind in the morning. That's a massive push of energy, and the conditions look clean. Another one for experts only – that size is serious. It’s over a week out, so treat it as promising but not locked in, but it has the potential to be the biggest and best day of the whole stretch. The water is also a bit colder than average for this time of year at 64°, so bring the thick rubber.
After that, it fades out. Thursday the 20th is back to marginal, and the 21st looks poor again with a risk of thunderstorms and strong winds. The 22nd and 23rd are back to big, but messy and onshore. Not worth it.
So to sum it up: don’t even bother looking at the water until Tuesday the 11th. The two real standouts are Wednesday morning the 12th for a clean, solid session, and Wednesday morning the 19th for the big one. Everything else is just waiting for the next window. Crowds might be an issue on those clean days, but when it’s this good, you don't mind sharing.
Stay safe 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.
