The Lowdown

Alright folks, Rusty here with a look at the next couple of weeks. We’re talking about Trigg Beach to start. Water temps are sitting right where they should be for this time of year.

We get going on Wednesday the 12th of August. Wednesday morning is a real beauty. A solid 7ft SW groundswell is rolling in with a long 15-second period. The wind is glassy, just a 5 km/h breeze from the NNE. The water will be like a mirror. Wave energy is moderate (1983). This is proper, powerful surf, and at 7ft, it’s for the experienced crew, not the beginners.

Thursday the 13th, another clean morning. An offshore ENE breeze at 5 km/h keeps it tidy. The swell is 7ft from the SW with a very long 16-second period. Energy is up (2299). Again, powerful and clean, but for experienced surfers only.

Friday the 14th morning is more of the same goodness. A solid 7ft SW swell, 16-second period, and a light cross-off breeze. Clean as a whistle.

Saturday the 15th sees the swell drop back to 6ft from the WSW. The wind is a moderate cross-off, so it stays clean.

Sunday the 16th is a big one. The afternoon session is a standout. We’ve got a clean 8ft WSW swell with a 15-second period and a gentle offshore cross-off breeze. The energy is strong (2545). That Sunday afternoon is your best bet in the first week for experienced surfers.

Monday the 17th gets ugly. The swell hits 10ft in the afternoon, but with a messy onshore wind. It’s big and choppy. This is more of a kite-surfing setup than a paddle session.

Tuesday the 18th morning, it’s back on for the experts. A huge 10ft WSW swell with a 16-second period, but the wind is offshore from the NNE, keeping it clean. Energy is very strong (4400). But at that size, it’s experts only.

From Wednesday the 19th through the 21st, it’s a write-off. Onshore gales, rain, and lumpy, terrible conditions. Forget it. The swell maxes out at 13ft, but it’s a total mess.

Thursday the 22nd morning, the swell is still huge at 12ft. The wind is favorable, but it’s just way too big for this spot. A no-go.

We get a little relief on Sunday the 23rd of August. The afternoon is glassy, with the swell dropping to 8ft from the WSW. Clean, glassy, and a 15-second period. A good option for the experienced crew after the big stuff.

Finally, Thursday the 27th of August shows another clean morning. Offshore breeze, a 8ft WSW swell with a 13-second period, and strong wave energy (2413). A solid, powerful morning.

All in all, the two to lock in are Wednesday the 12th morning and Sunday the 16th afternoon. Those are the cleanest, most powerful windows we’ve got.

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.
