The Lowdown
G'day, Rusty here. Alright, let's have a look at what's coming down the pipe for Trigg Beach over the next couple of weeks. It's a bit of a mixed bag, to be honest. The water's sitting at 64°, which is a touch colder than we'd normally expect for this time of year – about 2° cooler, so grab that extra wetsuit.
Right off the bat, we've got some solid swell rolling in, but it's going to take a few days for the conditions to clean up enough to be worth a paddle. Wednesday the 2nd and Thursday the 3rd are pretty average, with onshore winds and a bit of chop. The swell's there – a clean 7ft to 8ft from the WSW with good period (14-15 seconds) – giving us moderate to strong wave energy (1629 to 2305), but the wind just isn't playing ball. Thursday afternoon gets nasty with a 19 mph onshore wind, so give that one a miss.
Friday the 4th is a write-off. We're looking at a solid 10ft to 12ft swell from the WSW, but with cross-onshore winds and choppy conditions, it's a no-go for a paddle. The wave energy is moderate to strong (3706 to 4574), but honestly, with that wind, it might be more of a kite day.
By Sunday the 6th, there's a shift. The wind swings south and becomes cross-offshore, cleaning up that 10ft WSW swell. The wave energy is still strong (3310 to 4063), and the conditions are starting to look a lot cleaner. Sunday afternoon is the pick of the early days – still big, but clean.
Now, here's where it gets interesting. Monday the 7th morning is a real standout. We've got an 8ft swell from the WSW, but with a 16-second period, that's a proper groundswell. The wind is a light offshore from the ESE, keeping it glassy. The wave energy is strong (3977). This is excellent surf for experienced surfers – the size and power are there, but the offshore wind will make for some beautiful, clean walls at Trigg. The long period means it'll be a bit more lined up and powerful, so maybe not one for the beginners as it's over 5ft. Crowds are possible here, as it's often a busy spot, but for that quality, it'll be worth it.
After that, Tuesday the 8th keeps the same formula going. Morning and afternoon sessions both look excellent, with 8ft swell from the WSW, long periods of 15-16 seconds, and moderate to gentle offshore winds from the E. The wave energy is strong (2997 to 3636). This is another top call.
We get a bit of a lull in size through the middle of the week, with 6ft to 7ft swell on Wednesday the 9th and Thursday the 10th. Wednesday afternoon has light offshore winds, making it a decent session for those who want something a bit more manageable.
The next real standout is Saturday the 12th morning. We've got a 10ft swell from the WSW with a 16-second period, and the wind is a dead offshore from the E at just 3 mph – basically near-calm. The wave energy is very strong (4116). This is prime, glassy, powerful surf for the experienced crew. It's big (over 8ft), so this is an expert-only zone.
Sunday the 13th morning is a little beauty. A 6ft swell from the WSW, with 14-second period, and the wind is flat calm – glassy conditions. The wave energy is moderate (1396). This could be a sneaky good session for anyone after some clean, fun waves without the massive power.
Looking further out, from around the 14th of September, things start to get very, very big. We're talking 12ft to 16ft swells from the WSW, with wave energy shooting up to 6287 and even 10742. The forecast suggests the swell is just too big for Trigg – a classic beach and point setup that can get overwhelmed. The wind and tides look favorable, but the raw power will make it a dangerous proposition. There are a couple of glassy mornings in there (the 16th and 17th), but with 15ft to 16ft swell, it's strictly for the brave and the expert. This is a long-range call, so it's promising but not locked in.
So, to wrap it up: Monday the 7th morning and Saturday the 12th morning are the absolute standouts for clean, powerful, offshore surf. Don't sleep on Sunday the 13th morning for a quieter, glassy session either.
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.
