The Lowdown

G’day, I’m Rusty, and here’s the full picture for the next couple of weeks out of Trigg Beach (Trigg-Beach-and-Point). The water’s sitting at 64°, which is a bit colder than normal for this time of year—about 2° cool, so you’ll want a good wetsuit if you’re heading out early.

The real action kicks off Thursday August 6th morning, when everything comes together just right. We’ve got a solid 10ft swell from the WSW wrapping in with a 16-second period, carrying a very strong combined energy of 4348. That’s groundswell territory, and while it’s packing plenty of push, the long period means you’ll want to be smart about where you paddle out—Trigg’s a beach and point setup, so look for the points and reefs for the best shape. The wind is glassy, absolutely dead calm, so the surface will be like a mirror. That’s the standout of the entire forecast: clean, powerful, and if you’re an experienced surfer, this is your morning. It’s going to be a bit much for beginners though—over 8ft and solid.

The run-up to that day is a bit of a mixed bag. Monday August 3rd offers a 5ft clean wave with light cross-off wind, but the energy is moderate (766) and the score’s not great. Tuesday and Wednesday see the swell building but the wind swings onshore or cross-on, making it choppy and messy. By Wednesday afternoon the swell hits 10ft but the wind is onshore—big but blown out.

After the Thursday standout, Thursday afternoon sees the wind shift to a cross-on, and the swell drops to 8ft. Friday August 7th is a write-off with strong onshore winds and rain showers—stay on the beach. Saturday August 8th brings a massive 13ft swell from the WSW with a 14-second period, and combined energy through the roof at 5985. But the wind is cross-shore and moderate, and the forecast says it’s too big for this break. Only experts should even think about it, and even then, it’s a maybe.

There’s a gap of a few days of average conditions, then we get a run of cleaner surf starting Monday August 10th with a 7ft SW swell, light cross-off wind, and clean conditions—solid for experienced surfers. Tuesday August 11th morning is a cracker: 8ft SW swell, 15-second period, and a clean offshore breeze from the ESE. That’s another good window. Wednesday August 12th keeps it going with offshore winds and 7ft to 6ft SW swells, clean and fun.

The next real standout is Thursday August 13th. Morning sees an 8ft SW swell with a 20-second period—very long-period groundswell—and a clean offshore wind from the ENE. Combined energy is 5224, very strong. This is a big, clean, powerful day for the experts. The afternoon holds the same solid 8ft with offshore wind as well. That’s a full day of top-tier surf.

After that, things stay interesting but more mixed. Friday August 14th has clean offshore winds and 8ft swell, and Saturday August 15th brings 10ft with light cross-off wind—still clean but big. The final standout is Tuesday August 18th morning: glassy conditions, 8ft WSW swell with a 16-second period, and the combined energy at 2900. That’s a clean, solid morning for experienced surfers.

Overall, the two best windows are Thursday August 6th morning and Thursday August 13th all day. Mark those in the calendar.

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.
