The Lowdown
Alright, Rusty here. Let’s talk about what’s coming down the pipe for Trigg Beach.
Right off the bat, we’ve got a massive pulse of WSW groundswell arriving Friday morning, August 7th. It’s a solid 10 ft with a very long 15-second period, and the energy is strong at 3543. But here’s the rub: the wind is cross-on from the SSW at 6 mph, and the water’s a bit colder than normal at 64°. The morning is rideable if you’re desperate, but by Friday afternoon the wind swings onshore and it’s a write-off. Saturday, August 8th, is a complete mess – 15 ft swell and howling cross-on winds up to 28 mph, so don’t even bother.
Sunday morning, August 9th, the swell is still a chunky 12 ft (6347 energy), but it’s too big for Trigg Beach, a beach-and-point setup. The wind is light cross-on from the NW at 6 mph, but with a 16-second period, this is a proper groundswell. For a point break, that’s a good thing – the lines will hold, but it’s strictly for experienced surfers only. Sunday afternoon gets blown out again.
Monday, August 10th, the wind cranks up to 28-31 mph, and the swell jumps to 15 ft. This isn’t surf; it’s a washing machine. Kite surfers might love it, but for a paddle surfer, it’s a hard pass.
Now, Tuesday, August 11th, is the standout for the first week. The swell drops to 16 ft overnight – still huge – but the wind goes clean from the SSE at 9 mph, giving us clean conditions. The period is a very long 16 seconds, and the energy is massive at 23714. Again, this is only for experts; 16 ft is well into big-wave territory. The afternoon holds similar size with a cross-shore wind. Crowds are likely at Trigg, and with size like this, it’ll be a zoo.
Wednesday, August 12th, is the best call for most. The swell drops to 10 ft, still with that long 16-second period, but the wind goes glassy offshore from the NNE at 3 mph in the morning. Clean conditions, solid groundswell energy (4057), and it’s manageable for strong intermediates. The morning window is the pick. By afternoon it gets a bit choppy.
There’s a bit of a lull through the end of the week. Thursday, August 13th, the swell backs off to 7 ft, and winds are light but cross-on. Friday, August 14th, morning looks better – 8 ft swell, clean with a light offshore from the NE at 6 mph. That’s a nice little window for a session. Saturday, August 15th, the swell drops further to 6 ft, but winds are messy.
Looking into the second week, there’s a real promising run starting Sunday, August 16th. The swell bumps back up to 12 ft with a 14-second period, and winds stay light. But it’s probably too big again for Trigg Beach’s normal shape. Monday, August 17th, is the big one: 12 ft to 13 ft of WSW groundswell, with a 17-second period – that’s a very long period groundswell. The wind goes glassy in the afternoon. Energy readings are around 7937. This will produce long, powerful lines at the point, but it’s big. Only experts need apply.
After that, Tuesday, August 18th, gets blown out again with strong winds. Wednesday, August 19th, through Thursday, August 20th, holds solid 12 ft swell but with cross-on winds. Then Friday, August 21st, brings another bright spot: 10 ft swell with clean offshore winds from the ESE at 19 mph in the morning, and even better in the afternoon with offshore ESE at 12 mph. That’s a good session for experienced surfers.
Saturday, August 22nd, rounds it out with 8 ft swell and fresh offshore winds from the E at 19 mph, dropping to 12 mph in the afternoon. Clean, lined-up surf for the end of the forecast.
Best on offer: Wednesday morning, August 12th, for the combination of 10 ft groundswell, glassy offshore wind, and a long period that’ll draw perfect lines at the point. Monday, August 17th, is a close second for the sheer power and glassy afternoon conditions, but it’s only for the brave.
This is Rusty, signing off.

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.
