The Lowdown

Alright, this is Rusty.

We are looking at Trigg Beach for the next couple of weeks, and let me tell you, we have a bit of a rough start followed by some absolute gems. It's a beach and point setup, exposed fairly well to the west-southwest swell, and the water temp is sitting right about average for this time of year, nothing unusual there.

First off, the good news: we don't have a flat spell. There is swell on the way, but the first few days are a write-off. Friday the 4th and Saturday the 5th are total no-go's thanks to fresh cross-onshore winds making a mess of that solid 10ft south-west swell. The wave energy is through the roof, but it's just lumpy, choppy rubbish. Not worth getting wet for.

Sunday the 6th is where the switch flips. The wind swings to the southeast, clean cross-offshore, and that 13ft swell from the southwest kicks in. Now, that’s a big number. It’s a groundswell with a 13-second period, but at 13ft, this is strictly for the experts. Beginners, stay on the sand. It’s clean, but it’s a beast.

Monday the 7th settles a bit. We’ve got a solid 8ft swell from the west-southwest with a long 16-second period. The winds are clean and cross-offshore. The quality is marginal, but it’s a step in the right direction.

Now, the real standout. Tuesday the 8th is your pick of the first week. We’re looking at an 8ft west-southwest swell with a very long 18-second period. That’s the kind of groundswell that will wrap beautifully into the point. The wind is offshore from the east-southeast all day. Clean, lined-up waves for experienced surfers. This is the one.

Wednesday the 9th still holds with a slightly smaller 8ft swell and offshore winds.

The second week gets a bit messy. There’s a big gap of poor conditions from the 12th to the 14th with onshore gales that will ruin the 7ft to 8ft swell. Don’t bother. Things clean up again on the 15th with another solid 8ft swell and offshore breeze, but the magic really happens on the 16th. Wednesday the 16th of September is the long-range standout. We get a solid 8ft south-west swell with a 16-second period, offshore east-northeast winds. This is worth circling on your calendar, even if it’s a bit of a wait.

Later on, the 19th of September looks promising too, with another big 8ft west-southwest swell and a very long 18-second period. With light offshore winds, this could be a cracker for experienced surfers.

Crowds at Trigg are often around, so expect company on those good days.

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.
