The Lowdown
Alright folks, Rusty here. Let’s take a look at what Trigg Beach has on offer over the next couple of weeks.
Right off the bat, the first few days are pretty cooked. We’ve got a big groundswell rolling in from the WSW, but it’s arriving with onshore winds that are just going to chop it up. That Saturday and Sunday are a write-off, with poor conditions and a messy ocean. The swell is solid, around 6 ft to 8 ft, and the water is sitting at 64°, which is a touch cooler than average for this time of year, but nothing too unusual.
The real standout window shapes up on Monday the 14th. Clear skies, a light offshore breeze from the ESE, and a solid 8 ft WSW swell with a 14-second period. That’s proper groundswell energy (2392), and with the offshore wind, Trigg (Perth) will be absolutely peeling. This is the best day on offer and one for the experienced crew – that size will be too much for beginners.
The offshore flow hangs on through Tuesday the 15th, with the swell easing slightly to 7 ft but still packing a punch (1874 and 1700 combined energy). It’ll be clean and well-shaped, but nothing beats the quality of that Monday morning session.
We then hit a long lull. From Wednesday the 16th right through to the following Monday, the wind gets messy again, and the swell drops off or gets hammered by strong onshores. There’s a nasty spell on the 18th and 19th with an 12 ft to 13 ft WSW swell and gale-force winds – that’s just blown-out mayhem, and it’s going to be a real mess at the beach. No good for a paddle, maybe one for the kite crew.
After that, the next flicker of hope comes on Sunday the 20th. An 8 ft WSW swell, 13-second period, and a light offshore from the E again. The energy is still solid (2265), and it’ll be clean. Another good one for experienced surfers, but it’s a week and a half out, so keep an eye on it.
The last bit of interest is on Thursday the 24th. We’ve got a smaller 5 ft to 5 ft WSW swell, but moderate offshore winds from the E will keep it clean. The period drops to 12-13 seconds, so it’s less grunty, but it’ll be a fun, user-friendly size for most.
Overall, it's a stop-start forecast. Monday the 14th morning is your absolute winner. That’s the one to plan around. The surf after that is patchy, with long gaps of onshore junk and only a few clean respite days later in the period. Crowds are often an issue at Trigg, so get in early on those good days.
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.
