The Lowdown

Alright, Rusty here. Let's chop through this.

We're looking at a pretty average run at Trigg Beach (beach and point) for a while. The first real chance of a wave isn't until Wednesday the 16th, but we've got to work for it. The real gold is buried deep in the second week.

Wednesday the 16th gives us two options. The morning has a 5ft swell from the WSW, but that 25 km/h cross-offshore wind from the NE is going to make it messy. Not the top pick. The call for the day is Wednesday afternoon. We're talking glassy, dead calm conditions with a clean 4ft swell from the WSW. That's a no-brainer session.

Then the fun stops. From Thursday the 17th right through to Tuesday the 22nd, the wind turns onshore, the waves get lumpy, and the quality is poor. Friday the 18th sees the swell jump to 13ft, but with a 30 km/h cross-onshore wind, it's a complete mess. That's a kite-surfing session, not a paddle one. Just skip those days.

Monday the 21st has a whisper of a chance with a 7ft, 15-second period swell from the WSW. The wind is light, but the combined energy is at 2070 – it's still just a marginal call. You'd be rolling the dice.

The first week is a write-off until we get into the second week.

Here is the big call. Friday the 25th is a standout, but for experts only. A massive 11ft swell from the WSW with a very long 19-second period. The combined energy is a huge 7786. The forecast says it's predicted to be too big for this break. If you are a seasoned charger, the wind and tide are favorable, but for everyone else, it's a day to watch from the cliff. Saturday the 26th morning is even bigger – 15ft from the WSW with a 16-second period and over 10,000 combined energy. Same story. Too big.

Now, the real standout for the average surfer. Tuesday the 29th morning. After a week and a half of junk, we get a glassy morning with an 8ft swell from the WSW. That 19-second period is pure groundswell energy, giving you shape and power. The site calls it "excellent" for experienced surfers with a combined energy of 3860. This is the one to put in your calendar. Trigg does get packed, so be ready to share.

So, to wrap it up: The only real session in the first week is the glassy Wednesday afternoon. The second week brings a massive swell for experts only on the 25th and 26th, but the best bet for most of us is the beautiful, powerful groundswell on the morning of the 29th. Mark it down.

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.
