The Lowdown

Alright, Rusty here, looking at the surf ahead for Trigg Beach. We've got a bit of a mixed bag coming our way, but there are a few windows to keep an eye on.

The first decent opportunity hits on Monday the 14th of September with a morning session. The water's sitting at about 64°, which is pretty standard for this time of year, nothing unusual there. We're looking at a solid 8-foot swell from the WSW, with a long 14-second period, bringing plenty of energy – we're talking a combined energy of 2222 (moderate wave energy). The wind's out of the ESE at 6 mph, which is offshore, so expect clean faces. This is a big, powerful swell though, so it's one for the experienced crew only. The afternoon goes a bit average with a cross-shore breeze, so stick to the morning.

Tuesday the 15th is another cracker in the morning. The swell backs off a touch to 7 feet, still from the WSW, with that same long 14-second period. The wind stays offshore from the East at 12 mph, keeping things clean. The energy is still strong at 1900 (moderate wave energy). Again, this is expert territory. The afternoon is okay with a cross-offshore wind, but not as good.

Wednesday the 16th is a step down with the swell dropping to 5 feet, and the energy easing to 870. It's clean enough with a cross-offshore breeze, but nothing to get too excited about. Thursday the 17th is a write-off with onshore winds and messy conditions.

Now, the end of the week gets interesting again. Friday the 18th sees a new, short-period swell from the W at 8 feet, but the period is only 8 seconds, so it's going to be lumpy and weak. The energy is moderate at 1468, but with a strong cross-shore wind, it's a no-go for a surf. Later that afternoon, we get a massive 10-foot swell from the WSW with a very long 17-second period, and the energy jumps to 5723 (very strong wave energy), but the wind is a solid cross-onshore, making it a complete mess.

The weekend is a washout, with onshore winds and big, choppy surf. Not worth paddling out.

Looking further ahead, the morning of Sunday the 27th of September is a highlight. The swell drops to 7 feet from the WSW with a 16-second period, and the wind goes cross-offshore from the ENE. Clean conditions and a solid energy of 1956. The afternoon is even better, with the swell down to 6 feet, same direction, and a beautiful offshore breeze from the East at 6 mph. The energy is 1405, and it's clean and glassy for the experienced surfer.

Then, Monday the 28th of September morning looks magic. The swell is 6 feet from the SW with a 13-second period, and the wind is glassy – straight off the SSE at 3 mph. It doesn't get much cleaner than that. Energy is moderate at 1110. This is a standout for the period, offering really good conditions for those who know what they're doing.

After that, we get another big pulse on Tuesday the 29th of September, with 10-foot swell from the WSW, but the period is a short 8 seconds, so it'll be weak and messy. The cross-shore wind doesn't help. That's one for the kites, not the paddle.

Overall, the best bets are Monday morning the 14th and Tuesday morning the 15th for the first week, then Sunday the 27th and Monday the 28th for the second week. Keep an eye on the forecasts as we get closer, but those are the windows that are looking promising.

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.
