The Lowdown

Righto, let’s have a look at what’s comin’ down the line for Trigg Beach. This is a beach and point setup, fairly exposed to the swell, and it’s a fairly consistent spot, so if there’s a window, it’s usually worth a look.

The forecast is a bit of a mixed bag to start. We’ve got some serious size on the way, but the wind and conditions are gonna be the real decider. The first session that’s any good is on Wednesday afternoon, the 26th of August. That’s a real standout. The wind goes glassy, dead calm, and you’ve got a solid 12 ft of swell from the WSW, with a very long 18-second period. The combined wave energy is massive at 7956. It’s gonna be big, powerful, and clean—this is one for experienced surfers only, as it’s well over 8 ft. The swell direction is bang on the optimum.

Thursday the 27th morning is a write-off with a strong cross-shore, but the afternoon cleans up with a cross-off breeze and 10 ft of SW swell. Still a big, powerful wave, but the period is 15 seconds, so it’s proper groundswell. The energy is still high at 3525. That’s a solid session.

Friday the 28th drops off a bit in size, with 7 ft in the morning and 6 ft in the afternoon, both from the SW. The wind is cross-off and clean, but the energy is moderate, and the tide might be a factor. It’s not a standout.

The weekend of the 29th and 30th sees the swell size bounce around. Saturday morning is tiny at 3 ft, but the afternoon picks up to 5 ft with a very long 19-second period from the WSW. The wind is cross-off, so it’s clean, but the energy is low to moderate. Sunday the 30th morning is the best of the weekend: 8 ft of WSW swell, 18-second period, and a light offshore breeze. That’s a clean, powerful wave with 3164 energy. It’s still a big wave, so it’s for the experienced crew.

Monday the 31st looks a bit messy with cross-onshore winds and choppy conditions, so skip that.

The first week of September starts with a cracker. Tuesday the 1st of September morning has 8 ft of WSW swell, 16-second period, and a clean cross-off wind. The energy is 3556, and it’s clean. That’s an excellent session for the experienced.

Then we’ve got a real gem on Wednesday the 2nd of September morning. The wind is glassy, dead calm, and the swell is 7 ft from the WSW with a 14-second period. It’s clean, glassy, and the wave energy is 1633. That’s a beautiful morning for the experienced surfer.

Thursday the 3rd of September morning is another glassy one, with 7 ft of WSW swell, 14-second period, and 1987 energy. Perfect for the morning session.

The following Friday the 4th and Saturday the 5th of September mornings have clean, cross-off winds with 7 ft and 6 ft of WSW swell, respectively. Good, solid, clean waves.

The next standout is on Monday the 7th of September. The wind is offshore from the East all day, and the swell is 7 ft in the morning, building to 8 ft in the afternoon, with a 17-second period from the WSW. The energy is over 3000, and it’s clean. That’s a fantastic day for the experienced.

Tuesday the 8th of September afternoon is another big one: 10 ft of WSW swell, 17-second period, and a gentle offshore breeze. The energy is 4565. That’s a powerful, clean, big-wave session for experts only.

The rest of the period into the second week has smaller, cleaner waves, but nothing that really jumps out as a standout compared to the earlier big swells.

So, the two real standouts for me are the Wednesday afternoon glassy session on the 26th of August, and the big, clean, offshore session on Monday the 7th of September. Both are for experienced surfers, but they’ll be the ones to remember.

Stay safe out there.

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.
