The Lowdown

Alright, Rusty here, let’s talk about what’s coming up at Trigg Beach over the next couple of weeks.

Alright mate, straight up, the first week is a mixed bag of almost-there and full-on conditions, with a couple of standout windows if you’re willing to be picky. The water temp is sittin’ around 64°F, which is a touch cooler than usual for this time of year – a bit nippy, but nothing a good 4/3 won't fix.

We kick off Saturday the 12th of September, but forget about it – it’s onshore, choppy, and the swell energy is massive but messy. Not worth paddling out. Sunday the 13th is similar, garbage. The real first look comes Monday morning the 14th. Trigg Beach cleans right up with an offshore easterly breeze at 6 mph. Those 8ft waves from the WSW with a 14-second period have got some serious grunt – combined energy is 2392 (moderate) and it’s a groundswell. That long period means it’ll be a bit straight at the beach, but with glassy, offshore conditions, it’s clean and powerful. This is one for experienced surfers only at that size.

Tuesday the 15th is another solid shout. You’ve got a stiff easterly offshore at 16 mph keepin’ it clean, with 7ft of WSW swell – still solid. Combined energy is around 1900, and the period is 14 seconds again. It’s a full day of clean, powerful waves for the experienced crew. Really nice autumn feel to the air. The standout of the whole run, though, has to be Monday the 21st of September. Monday afternoon, the wind eases to a light 9 mph cross-off from the NNE, the swell is a good 7ft from the SW with a long 16-second period, and it’s clean – combined energy is 2444. This is the one to circle in the calendar. It’s not too big for the good surfers, and the setup looks juicy.

Don’t sleep on the morning of Thursday the 24th either, but you’ll want to be an expert. Swell is pumping 12ft from the WSW with a very long 19-second period – combined energy is a whopping 9520. That’s proper groundswell territory. Too big for most, and it’s a cross-shore wind, so it’ll be lumpy. Only the groms with serious balls should go near it.

The second week starts to wind down. Friday the 25th still has some size – 10ft in the morning – but the wind is good from the SE, keeping it clean. By Saturday the 26th of September, it’s dropping to 5ft with a clean offshore, but the energy is fading. After that, the last few days of the outlook are small, weak, and not really worth the wetsuit peel. Swell drops under 4ft and period drops, with rain about. Bit of a flat finish for the run.

Overall, don’t bother paddling out until Monday morning the 14th, then smash Tuesday the 15th and especially Monday the 21st. That Monday is the pick.

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.
