The Lowdown

G’day, Rusty here. We’ve got a mixed bag coming up at Trigg Beach over the next couple of weeks, so let’s get into it.

The first real standout window kicks off on Monday, September 8th, and holds through Wednesday the 10th. That’s where the goods are. Trigg is a beach and point setup, fairly exposed to the WSW swell, and the water temp is sitting at 64°, which is a touch below average for this time of year – nothing too dramatic, just a little cool.

Let’s start with Monday morning, September 8th. We’ve got clean conditions with offshore wind from the ESE at 13 mph, swell around 8 ft from the WSW, and a long period of 16 seconds. That’s proper groundswell energy, with a combined moderate to strong energy of 3870. The point should really shine here, with those long lines wrapping in. It’s big enough that beginners might struggle, but for intermediates and up, it’s a beauty. Monday afternoon stays clean with lighter ESE winds at 10 mph, same 8 ft swell, and still that lovely 16-second period – a solid day all round.

Tuesday September 9th is the best on offer. Morning has offshore wind from the E at 13 mph, swell at 8 ft, WSW direction, 15-second period, and combined energy of 3728. Afternoon even better: clean glassy conditions, ESE wind at 10 mph, swell bumping to 10 ft, 16-second period, and strong energy of 4071. That’s expert territory, so if you’ve got the skills, this is the session to chase. Crowds are *often* here, so expect company.

Wednesday September 10th holds the quality. Morning has ENE offshore wind at 13 mph, 8 ft swell, 16-second period, and 2786 energy. Afternoon is lighter with 10 mph offshore, 7 ft swell, still clean – a great way to end the run.

Thursday September 11th starts to fade a bit. Morning has light NE cross-off wind at 6 mph, 6 ft swell, and 15-second period, but the energy drops to 1389. Still clean, but fading. Afternoon goes messy.

There’s a big gap after that. Friday and Saturday are mostly poor to marginal, and Sunday September 14th is the next call. Monday September 15th morning is glassy with zero wind, swell at 7 ft, WSW, 14-second period, and moderate energy of 1874. That’s a clean, fun session for experienced surfers, just smaller than the earlier peak.

After that, we’re into smaller, weaker swell for the rest of the window – not much to get excited about.

So overall, the pick is Tuesday September 9th afternoon at Trigg: 10 ft WSW groundswell, 16-second period, gentle offshore wind, clean conditions – that’s as good as it gets around here.

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.
