The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for Trigg Beach and I've got the goods for you.
Right off the bat, we’ve got a bit of a wait on our hands. The start of the forecast period on Thursday, September 3rd, is a write-off—big cross-onshore wind and a messy 8ft to 8ft swell. The whole first weekend looks blown out, with the combined swell energy sitting north of 3000 (moderate to strong) but hammered by onshores and even some rain and storms. Honestly, it’s a kite surfer’s paradise right now, not a paddler’s. Don't even think of paddling out until we get a change.
The first real glimmer comes on Monday the 7th. The wind swings around to a cross-offshore from the ESE, and while the swell drops to 8-8ft, it’s a long-period 16-second groundswell from the WSW. That energy is still up there (around 2900 to 3870), and the conditions are clean. It’s still a bit on the bigger side for beginners, but for an intermediate, Monday afternoon with that light seabreeze looks very tempting.
But the standout, and I mean the true standout of this entire outlook, is Tuesday the 8th and Wednesday the 9th. This is where it all comes together. On Tuesday, we get clean, moderate offshore winds (ESE) all day, whipping that WSW swell at 8ft into shape. The period is still a solid 16-17 seconds, and the combined energy spikes to 4414 on the morning—that’s strong, powerful surf. This is excellent, clean conditions for experienced surfers, pure and simple. Wednesday follows suit with lighter offshores from the east and ENE, still holding at 7-8ft with that long period. If you can only get in the water for one or two days, make it the 8th and 9th.
Things get smaller and a bit sloppier towards the end of the first week. Thursday the 10th drops to 5-5ft, and the wind goes cross-onshore again. Not great.
The weekend of the 12th and 13th (Saturday and Sunday the 12th-13th) sees the swell push back up to 10ft, with that WSW direction and 15-16 second periods. The combined energy is back over 4000 on the Saturday afternoon. Sunday morning is the pick here, super light winds and clean conditions, but that 10ft is definitely expert territory.
After that, the second week looks like a slow fade. A final decent run on Monday the 14th with clean cross-offshores and 8-8ft swell, but from Tuesday the 15th onward, the heights drop below 6ft, and by Wednesday and Thursday the 16th and 17th, the wind goes funky and choppy again. The 18th looks like a return to the big, blown-out stormy stuff (10ft and cross-onshore). Not worth the drive.
So, to keep it simple: wait until Monday the 7th for the first clean ones, but the real magic happens on Tuesday the 8th and Wednesday the 9th at Trigg. That’s your window. Get amongst it.
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.
