The Lowdown
Alright, Rusty here. Let’s break down what’s cooking at Trigg Beach over the next couple of weeks.
We’ve got a slow start. The first real chance is Saturday morning, August 29th. The swell is a small 3ft from the WSW, but it’s got a super long period of 19 seconds. That’s a proper groundswell that’ll wrap in nicely. With a clean offshore east wind at 16 mph, the surface will be glassy. Water temp is about 65°, which is pretty average for this time of year. Wave energy is moderate (819). It’s a bit marginal, but it’s a start.
The action picks up that same Saturday afternoon. The swell jumps to 6ft from the WSW, still with that excellent 19-second period, and the wind shifts to a clean ESE offshore at 12 mph. The wave energy is now strong (1947). This is powerful, well-ordered surf for experienced surfers.
Sunday, August 30th, is the real standout. The morning is mint. We’ve got 8ft of WSW swell at 18 seconds, with a light 6 mph NE cross-offshore breeze. The surface will be clean, the energy is strong (3237). That’s the one to aim for. The afternoon sees the wind turn light cross-onshore, so it’ll get a little bumpy, but the size holds.
From Monday the 31st through the end of the first week, onshore westerlies and messy conditions move in. The swell stays a decent 7ft to 7ft, but it’s onshore junk. Not worth a paddle.
The second week has a couple of highlights. On Sunday, September 6th, the morning looks promising with a clean 10ft WSW groundswell at 14 seconds and a light cross-offshore SSE breeze at 6 mph. That’s solid energy (2948) but will be too big for beginners. Then Monday, September 7th morning, we get a glassy 7ft SW swell at 16 seconds with a 3 mph SE breeze. Clean as a whistle.
Late in the window, around the 12th and 13th, we’re looking at massive swell—up to 13ft from the WSW. The wave energy readings are huge, but the wind is predicted to be onshore or cross-onshore. That size is too big for this break and will be all crumble and chop. Kite surfers might like the wind and size, but for us on a board, it’s a day to sleep in.
The best bet: Sunday morning, August 30th, for the cleanest, most powerful surf. Saturday afternoon is a solid second. The Sunday and Monday mornings of the second week (Sept 6th and 7th) are worth keeping an eye on, but don’t book your flights yet. If the first week lightens up, it’s not unusual for this area and forecasts can change.
This is 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.
