The Lowdown
Alright, Rusty here. Let’s break it down.
Water temp at Trigg Beach is about 64°F, which is just a touch under the norm for this time of year—nothing crazy.
Monday the 14th is your first real shout. Early morning at Trigg Beach sees a clean 8ft swell from the WSW, 14-second period, with a light easterly offshore breeze. That’s clean, punchy surf with solid energy—2222. It’s for the experienced crew, but it’s a beauty.
Tuesday the 15th keeps it rolling. Morning brings a clean 7ft swell with an offshore easterly at 12 mph. The afternoon stays clean with a 7ft swell and a cross-off breeze. Both sessions are solid.
Wednesday the 16th drops off. Afternoon glass-off is the pick—4ft swell, glassy, light wind. Smooth and easy.
Thursday the 17th and Friday the 18th are rough. Onshore junk. Friday even has a short-period 10ft swell from the W at 8 seconds—messy and choppy.
Saturday the 19th has a 10ft WSW swell but it’s cross-on and messy. Kite surfers might dig it, but not for paddle surfing.
Tuesday the 22nd morning is glassy with a 5ft swell and 14-second period. Clean and fun.
Now the big one. Saturday the 26th. Trigg Beach fires. Morning has a 10ft SW swell with an 18-second period—that’s a very long period groundswell. Energy is massive at 6164, and it’s clean with a cross-off breeze. Afternoon goes offshore with 10ft, 17-second period, and energy at 5064. This is for experts only. Long period swells at Trigg’s point and reef setup are world-class. Expect a crowd, but if you’re good enough, this is the day.
Sunday the 27th eases with a 6ft swell and clean conditions. Monday the 28th drops back to poor cross-on surf.
Standout: Saturday the 26th at Trigg Beach. Circle it.
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.
