The Lowdown

Alright, Rusty here. Let’s talk Trigg.

We’ve got a long stretch ahead, but it’s gonna be a rough start. The first recommendation doesn’t come until Sunday the 9th, so you’re looking at a gap of a few days with nothing good to chase. Trigg has a big, powerful groundswell running through the whole period, but the wind is just plain ugly for the first few days – strong onshores and cross-onshores making a mess of things.

The real standout, the one you want to circle, is Thursday the 13th on the morning session. The water is sitting at 64°, which is a bit colder than normal for this time of year, so don’t expect a warm one. The swell is a solid 7ft from the SW, a long-period groundswell at 15 seconds, so it’ll have plenty of energy (combined energy 2242). The wind is a light offshore from the NE, so the lines will be clean. This is a good one for experienced surfers – the size and power will make it a handful for beginners. Trigg is a beach and point setup, so that long period should wrap in nicely.

Friday the 14th morning is another good call. The swell bumps up a touch to 8ft from the SW with a very long 17-second period, and the wind is offshore again from the ENE. The wave energy is up there (3625), and it’s clean. Again, that size means it’s for the experienced crew.

Sunday the 9th morning is the first decent look, but don’t get too excited. The swell is a massive 12ft from the WSW with a 17-second period and a massive energy level (7111). The wind is cross-off from the NNE, so it’ll be clean, but it’s predicted to be too big for the break. That’s a “big wave” session for experts only.

Tuesday the 11th is another day where the swell is just too big. We’re talking 16ft and 13ft with a 17-second period, and the combined energy is through the roof (14485 and 16146). The wind is okay, but the size is for the brave and the experienced.

The second week gets a bit more promising. Thursday the 21st morning is a beautiful glassy session. The wind is offshore from the NE, dropping to 3 mph, and the swell is a manageable 10ft from the WSW with a 13-second period. The energy is moderate (3528). This is a great all-rounder for experienced surfers, and the glassy conditions will make it a dream. The afternoon is even better – glassy, with a clean 10ft swell. This is the pick of the second week.

Don’t bother with the 16th through the 19th – it’s back to messy onshore winds and big, lumpy swell. Remember, break quality and consistency aren’t the best here, but when the wind lines up, Trigg can give you a proper session.

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.
