The Lowdown

Alright, Rusty here. Let’s take a long look at what’s coming our way. There’s a big gap at the start here with no real surf to speak of right now, so we’re looking ahead a few days before things kick off proper.

The first proper call is Wednesday morning, the 9th of September. We’ve got a solid 7ft groundswell out of the WSW, and that’s packing some serious energy (2200). The morning starts clean with a moderate offshore breeze out of the ENE at 15 mph. This is intermediate-level stuff, and the water’s sitting at 63°, which is a touch cooler than usual for this time of year. Trigg Beach is fairly consistent and fairly exposed, and the optimum swell direction lines up nicely with what’s coming. It’s a decent start, but the afternoon cleans up even more with lighter E winds at 9 mph and the same size swell – that’s the standout of the first day.

Thursday the 10th drops off a bit. Swell eases to 5ft in the morning, and the wind swings cross-offshore. It’s still surfable but nothing to write home about. Friday the 11th morning offers another clean window with 5ft and a gentle N breeze at 9 mph, but the wind turns onshore in the afternoon and the period jumps to 19 seconds – that long period can make a beach break tricky, as it tends to break a bit straight.

Saturday and Sunday the 12th and 13th are onshore and messy. Not worth getting excited about. Monday the 14th morning, though – that’s a beauty. 8ft of WSW swell with a light offshore breeze out of the ENE at just 6 mph. Clean, solid, and moderate energy (1991). That’s a proper session for experienced surfers.

Tuesday the 15th holds 8ft in the morning but the wind is cross-shore, and by the afternoon a fresh 19 mph cross-onshore kills it. Wednesday the 16th morning is clean again – 7ft, light cross-offshore breeze, good energy. Another solid morning.

Then we hit a bit of a lull. Thursday and Friday the 17th and 18th are poor, with onshore winds and dropping swell. Friday afternoon gets lumpy and ugly. Saturday the 19th is a write-off – huge 16ft swell but 25 mph onshore winds. That’s not surfable. Sunday the 20th drops to 10ft with light cross-shore wind, but it’s still big and choppy.

Now, here’s the real standout. Monday the 21st of September morning – glassy. Zero wind, 7ft WSW groundswell with a 15-second period, and excellent energy (2135). That’s as clean as it gets. Trigg will be firing for those who can handle it. The rest of that day goes cross-shore and choppy, but that morning window is the best on offer across the whole run.

Tuesday the 22nd and Wednesday the 23rd mornings both look promising too – 8ft and 8ft with clean conditions and offshore winds. The energy is strong, and the swell direction is right on the money. If you’re after a run of good waves, that stretch from Monday to Wednesday in the third week is your window.

Overall, don’t bother with the first few days of the second week. Focus on Monday the 14th morning, and then the real prize is Monday the 21st morning – glassy, solid, and clean. That’s the one.

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.
