The Lowdown

G’day, Rusty here. We’ve got a big run of groundswell coming in for Trigg Beach, but you’ll have to be patient through some messy early days before the magic sets in. It’s a beach and point setup here, exposed to a west-southwest swell, and right now the water’s sitting about a degree colder than normal for this time of year, so a little extra rubber might be the go.

The first few days are a write-off. Friday the 4th and Saturday the 5th are flogged by strong cross-onshore winds and lumpy, choppy conditions. The swell’s there – around 10ft to 12ft – but the breeze has it sloppy and the combined swell energy is strong (around 3697), but honestly not worth paddling out for.

Sunday the 6th cleans right up. The wind swings cross-offshore, leaving the waves clean with a solid 10ft of WSW swell and moderate wave energy (3399). It’s still a bit raw for beginners at that size, but for the experienced crew, this is where it starts to get good.

The standout window hits Monday the 7th and Tuesday the 8th. Monday morning brings clean conditions with gentle cross-offshore winds, a 8ft WSW swell and a very long period of 16 seconds – that groundswell energy is pumping (combined energy of 3726). This is excellent surf for those who know what they’re doing. The point break setup at Trigg will handle that long-period energy beautifully, giving you proper, lined-up waves. Tuesday follows with similar size and an even crankier 17-second period, plus offshore winds in the afternoon. The combined energy jumps way up to 4206 – strong stuff – and the waves will be clean, powerful and pushing through.

Wednesday the 9th stays clean with offshore winds and a dropping swell around 7ft to 8ft. Still excellent for experienced surfers, but the energy is easing off a touch (2550).

After that, the swell drops back through Thursday and Friday the 10th and 11th, with clean, smaller waves around 5ft to 6ft, but that’s more accessible for intermediates. Winds stay favourable.

Saturday the 12th and Sunday the 13th are a total mess again. Strong onshore gales and windswell pumping up to 15ft, but with rain and howling winds – that’s kite-surf territory, not paddle surf.

Monday the 14th sees a massive 13ft WSW groundswell with 14-second period, but it’s predicted to be too big for Trigg Beach. Combined energy is huge (6896) – that’s for experts only if anywhere, but realistically the break is likely maxed out.

The week after that, Tuesday the 15th and Wednesday the 16th offer a return to clean, smaller conditions. Tuesday morning is the pick: light offshore winds, 8ft clean waves and moderate energy (2053). Good, fun surf for competent surfers.

Thursday the 17th sees a late pulse of long-period WSW swell (18 seconds) at 8ft to 8ft, but the wind goes cross-onshore in the afternoon, making it a bit messy. Friday and Saturday the 18th and 19th are poor again, with strong onshore winds and rain closing things out.

So the best of the lot is clear: Monday the 7th through Tuesday the 8th. Clean, offshore winds, head-high to overhead WSW groundswell, and that long period – Trigg Beach (Perth) will be holding some beautiful lines. Be there early.

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.
