The Lowdown

Alright folks, Rusty here. Let's talk about the surf at Trigg Beach for the next couple of weeks. It's a bit of a rollercoaster, so pay attention.

We've got a big, powerful swell on the horizon, but the wind is going to be a problem for the first week and a half. The early days are ugly. Thursday the 6th kicks off with a solid 10-foot WSW groundswell, but it's got a 16-second period and a ton of energy. That's a proper long-period groundswell, but with a cross-onshore wind, it's just going to be choppy and messy. Friday the 7th and Saturday the 8th are worse. The swell actually builds to 15 feet on Saturday. The wind is howling, and the whole thing is a blown-out mess. Honestly, for a few days there, the wind is so strong it might be more interesting for the kite surfers than us paddle guys.

Sunday the 9th morning is a tease. The wind drops to a light breeze, but the swell is still a solid 12 feet from the WSW with a 17-second period. The energy is massive, and the combo looks good, but the break is calling it too big for Trigg. It's a big, powerful groundswell that'll be breaking straight on a beach setup, so it's a pass unless you're a real expert. The same story carries through Monday the 10th and Tuesday the 11th, with onshore winds and ugly conditions. Tuesday morning the 11th has a glassy 16-foot swell with a 17-second period and energy through the roof, but it's simply too much for the break.

Now, here's the hope. Wednesday morning the 12th is the one to circle. The swell drops to a more manageable 10 feet from the WSW, still with a long 16-second period, but the wind goes glassy. It's a rare moment of perfect conditions. The water is a bit colder than normal for this time of year. It's a stand-out session for experienced surfers only, as that 10-foot groundswell on a beach and point setup is still a lot of water. The energy is moderate, but the quality will be there.

After that, things settle down. Thursday the 13th and Friday the 14th see the swell drop to a more user-friendly 7 feet from the SW. Friday the 14th is a beauty, with a clean offshore breeze from the east all day. The swell is still a long 16-second period, which normally can be a bit straight at a beach break, but with offshore winds and smaller size, it'll be reeling. It's a solid day for the intermediate crew.

The following week is a bit of a lottery. We get another pulse of 13-foot swell on the 19th, with high energy and offshore winds, but again, it's likely too big for Trigg. The 21st of August, Friday, looks promising with a lighter 10-foot swell and a clean offshore breeze from the ENE. Still a long way out, but one to keep an eye on.

So, the best of the best? Wednesday morning, the 12th. That glassy, 10-foot WSW groundswell is the standout. Experienced surfers only, but it'll be perfect. The second pick is Friday the 14th, for a cleaner, smaller, and more accessible day for the intermediate crew.

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.
