The Lowdown

Alright, listen up. Trigg’s got a run of proper WSW groundswell coming through, with periods mostly hanging around that 14-second mark – that’s real groundswell with some grunt behind it. Water temp is sitting right on 64°, which is about normal for this time of year. Energy levels are all over the place, from weak to strong, but there are definitely some windows to get a wave.

Tuesday morning is the opening act – clean, light offshore wind, swell at 7ft out of the WSW, period 14 seconds. Energy’s at 1987 – moderate but with that long-period push. Clean, lined-up surf, and a bit meaty. Not a beginner wave at this size. Afternoon stays clean with a cross-off, still around 7ft.

Wednesday morning drops a touch to 5ft, but that northeasterly cross-off keeps things clean. It’s weaker, energy down to 870, so smaller and more user-friendly. The afternoon is the quiet gem though – glassy conditions, wind barely there, 4ft of clean lines. That’s your mellow session.

Thursday turns ugly – cross-onshore, choppy. Don’t bother. Friday is worse, with that strong westerly wind up to 50 km/h in the afternoon – it’s gonna be a mess.

Saturday jumps up to 10ft but it’s onshore and messy. Lumpy, wind-blown, not your day. Sunday backs off to 6ft but the wind is still cross-onshore and it’s fairly choppy. Tough to find a clean one.

Monday the 21st – morning has 7ft at 15 seconds, but the wind is light onshore. Not clean, but there’s a lot of water moving. If you can find a sheltered corner, there’s something there. Afternoon goes downhill with a cross-onshore chop.

Tuesday is more of the same – okay size but choppy. Wednesday is small and onshore. Marginal.

Now, hold out for Thursday the 24th afternoon – that’s when things get real. Swell jumps to 10ft at 16 seconds, energy at 5026. It’s cross-shore and a bit lumpy, but there’s serious power. It’s a handful.

Friday the 25th is the big one. Morning sees a massive 13ft WSW groundswell at 19 seconds, energy reading 12166 – that’s strong, very strong. Wind is light offshore out of the southeast, so it’s clean, but this is big. Forecast says it might be too big for this break. Expert territory only. If you’re a charger, this is it. The afternoon is big too, but that southerly wind picks up and makes it cross-shore and lumpy.

Saturday the 26th – still solid at 8ft, but the wind is cross-off and it’s clean. Good power, 3278 energy, and the afternoon is even better with a light cross-off at 7ft. This is where you want to be if Friday was just too heavy.

Sunday the 27th – still 6ft, but the morning is clean with a cross-off. Good quality. The afternoon gets more cross-shore chop.

Monday the 28th – morning is a beauty. 8ft at 15 seconds, light cross-off, clean, energy at 2387. Another excellent window for experienced surfers.

After that, it fades. Tuesday is small and onshore, and Wednesday drops right off – 3ft to 3ft, tiny, and while it’s clean, there’s just not enough push. The run is done.

So, the real highlights are Friday the 25th morning for the big-swell crew – that’s a serious, powerful, clean session if you’ve got the skills – and Saturday the 26th looks like the more accessible standout, with solid size and good winds. Keep an eye on Monday the 28th morning too. Crowds could be a factor at Trigg on the good days, but on a solid swell, there’s enough to go around.

Rusty out.

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.
