The Lowdown

Hey folks, Rusty here. Let's get you the lowdown for Trigg Beach over the next couple weeks. We got a full schedule of swell, but it ain't all a green light.

The main source of energy is a long-period groundswell from the WSW that comes in strong, reading over 2000 units of combined energy, which means a lot of power in the water. The trick is matching that with the right wind.

The first real standout is Monday morning, September 14. We're talking clear skies, a light 6 mph offshore easterly breeze, and a clean 8-foot swell from the WSW. Conditions are gonna be excellent for the experienced surfers. You'll have long lines wrapping the point.

Tuesday the 15th is the same story – offshore wind again, both morning and afternoon, with a solid 7-foot swell. Clean conditions for the whole day. Wednesday the 16th is a good call for the fun board. Swell drops to a playful 4 feet, but the afternoon turns glassy and calm. A perfect day for the longboard.

From Thursday the 17th through Saturday the 19th, the wind turns sour. We’ve got strong, lumpy cross-onshore winds, and the swell gets messy. Those are days to stay on dry land or, if you’re a kiter, you might have a ball.

We get a great reset on Sunday morning, September 20. The wind is light and cross-offshore, the swell is a solid 7 feet with a 13-second interval, and the waves will have some good push on the takeoff.

After a few more average days, the swell builds again towards the end of the outlook. Friday morning, September 25 is the big dog. A massive, clean 12-foot swell with an offshore breeze, producing huge combined energy (over 2900 units). That is an expert-only wave at Trigg. Friday afternoon looks equally as good, with a 10-foot swell and a cross-off breeze.

The best windows for a clean, manageable surf are the mornings of the 14th, 15th, and 20th. The big expert session falls on the 25th.

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.
