The Lowdown

Alright folks, Rusty here. Let’s have a look at the Trigg Beach outlook for the next couple of weeks. It’s a bit of a mixed bag, but there are a couple of windows where it’ll be worth paddling out.

There’s a bit of a wait for the good stuff. The early period is messy and blown out, but we’ve got a couple of standout mornings on the horizon. The best of it looks to be Tuesday the 15th and then a real belter further out on Saturday the 26th.

Let’s start with that first window. Trigg Beach, being a beach and point setup, is going to need the right wind to clean up. The water temp is sitting at 64°F, which is about average for the time of year. On Monday the 14th, it’s a write-off: 8ft of WSW swell but it’s blowing a cross-onshore and the energy is strong but messy (2073). Skip it.

Tuesday the 15th morning is where it’s at. We’ve got a clean 7ft WSW swell with a 14-second period. That’s a nice groundswell with some serious push. The wind is offshore from the East at 12 mph, setting up clean, lined-up waves. The energy is strong (1987) but it’s manageable. This is a solid intermediate session, maybe a bit much for the beginners with the size over 5ft. Tuesday afternoon stays clean with a cross-off breeze, but the swell drops slightly to 7ft.

Wednesday the 16th is smaller and cleaner, with 5ft to 4ft on the cross-off, but it’s not the standout. The rest of that week goes downhill fast with strong onshore winds and messy conditions, including a 31 mph westerly on the Friday the 18th that will shred the ocean. That’s kite-surfing territory, not paddle surfing. The swell gets big again Saturday the 19th and 23rd of September with 10ft on the face, but it’s onshore and blown to bits, so no good for us.

Now, hold onto your leash for the big one. Saturday the 26th of September is a proper standout, well over a week away so keep an eye on the long-range models. The morning shows a 8ft SW groundswell with a 16-second period. This is that very long-period energy that will wrap beautifully into the point. The wind is offshore from the East at 12 mph, making for epic, clean conditions. The energy is very strong (2973) so there’s plenty of power. This is an expert-only session with the size over 8ft at peak. The afternoon is still excellent, dropping to 7ft, light cross-off from the SE. Trigg will be the spot that day.

Sunday the 27th is still fun with clean 6ft waves, and Monday the 28th finishes with another excellent run of clean, cross-off 6ft swell from the WSW with a 16-second period. The crowd factor at Trigg is noted as “often”, so expect company on those good mornings.

So to sum it up: wait for Tuesday the 15th early, and circle Saturday the 26th. That’s the one to plan for.

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.
