The Lowdown

G’day, Rusty here. Let’s see what Trigg Beach is serving up for the next couple of weeks. It’s a proper mixed bag, with some absolute gems and a few days you’ll wanna sleep in.

We start slow, but things kick off properly from Monday the 14th. The water’s about 64°, which is normal for this time of year.

Monday the 14th morning is your first real standout. Trigg Beach is lookin’ at a solid 8ft swell from the WSW with a 14-second period – a solid groundswell. The real deal is the offshore wind, a light 6 mph easterly, keepin’ those faces clean. The combined wave energy is pumpin’ at 2222 (moderate to strong energy). This is excellent surf for experienced surfers – a bit of size but manageable. The point section should handle that long-period swell nicely. Crowds can be often here, so get in early.

Tuesday the 15th morning is another beauty. Slightly smaller at 7ft, same WSW direction and 14-second period, with a moderate 12 mph easterly offshore. Combined energy is still strong at 1900 (moderate to strong). Conditions will be clean and lined up – another good one for the experienced crew.

Wednesday the 16th afternoon is a curious one. The swell drops to 4ft from the WSW, 14-second period, and combined energy down to 561 (weak to moderate). But the wind goes glassy – zero mph. The waves will be tiny but pure. Expect some fun little clean-up sets for a longboard. It’s not a standout for power, but for pure tranquility, it’s a treat.

After that, onshores and chop mess things up through Thursday the 17th and Friday the 18th. Friday afternoon sees a jump to 8ft but it’s cross-shore with a cross-chop and combined energy blastin’ to 3210 (strong to very strong). It’ll be a washing machine – more for the kite crew.

Saturday the 19th looks rough with a strong 22 mph onshore and lumpy 8ft swell. Sunday the 20th and Monday the 21st are average.

But then, another real standout window. Tuesday the 22nd morning is back on. Clean 6ft from the SW, 14 seconds, with a light 9 mph ESE offshore. Combined energy is 1533 (moderate to strong). Perfect for a solid session on the point.

Wednesday the 23rd is even better. Morning has 6ft SW swell with a 16-second period and a light 6 mph ENE offshore – combined energy 1961 (moderate to strong). The afternoon session is the absolute highlight of the whole forecast. Same 6ft but the period stretches to 17 seconds – that’s very long-period groundswell. Offshore breeze is 9 mph ESE, and the combined energy jumps to 2189 (moderate to strong). This is gonna produce some beautifully shaped, powerful waves. The point should offer up some classic lines. This one’s for the experienced crew.

The last week gets wild. Thursday the 24th and Friday the 25th have more size but messy winds. Then a lull. But look out for Monday the 28th – the morning shows a massive 12ft WSW swell with a 14-second period and a fresh 22 mph offshore from the ENE. The combined energy is a huge 4690 (strong to very strong). That’s expert territory only – way too big for beginners. The wind is clean, but that much juice at Trigg is gonna be heavy. The point might hold some big ones for the brave. Afternoon sees it back to 10ft with a moderate offshore – still solid.

So, the real standouts are Monday the 14th morning, Wednesday the 23rd afternoon, and for the brave, Monday the 28th morning.

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.
