The Lowdown
G’day, Rusty here. Look, we’ve only got one break on the table for this stretch, and that’s Trigg Beach. It’s a beach and point setup, so it can handle a bit of swell but it’s not a secret spot. The water temperature is sitting at 64°F, which is about 1.8°F cooler than usual for this time of year, so factor that into your wetsuit choice.
The week kicks off this Sunday morning, 6 September. There’s a solid 8.2ft groundswell from the WSW, with a period of 13 seconds, and the combined energy is moderate at 2331. The wind is a cross-off from the SSE at 19 mph, which is decent but not glassy. The surf is clean but the forecast says it’s only marginal, so don’t expect perfection. The morning session is your best bet, with the same 8.2ft swell, though the afternoon’s a bit lighter at 7.5ft.
Monday, 7 September, mornings are the standout. The swell holds at 8.2ft, but the period jumps to 16 seconds – that’s proper long-period groundswell, which means better shaped waves and more energy. The combined energy is strong at 3726. The wind is a gentle cross-off from the ESE at just 9 mph, making for clean conditions. This is a good one for experienced surfers. The afternoon gets windier, with a fresh breeze picking up to 19 mph, so don’t hang around too long.
Tuesday, 8 September, is the pick of the week. Morning sees 8.2ft swell from the WSW, a long 17-second period, and strong energy at 3657. The wind is offshore from the ESE at 19 mph, giving you fresh offshore and clean lines. The afternoon is similar, with 8.2ft swell, 16-second period, and a moderate offshore breeze at 16 mph. This is excellent for experienced surfers – big, clean, and powerful. If you’re not an expert, it’s going to be a handful.
Wednesday, 9 September, keeps the run going. Morning has 7.2ft swell with a 16-second period, fresh offshore wind from the E at 19 mph, and energy at 2386. The afternoon drops to 6.9ft but the wind is lighter at 12 mph, still offshore. Both sessions are clean, and the afternoon is rated excellent for experienced surfers.
Thursday, 10 September, the swell starts to back off. Morning has 5.2ft, 15-second period, and moderate energy at 1166. The wind is a cross-off from the NE at 16 mph, clean but not as punchy. The afternoon is smaller at 4.6ft. It’s still surfable but nothing to write home about.
Friday, 11 September, things get messy. Morning has 4.9ft but the wind is cross-on from the NW at 12 mph, making it choppy. The afternoon is onshore, 3.9ft, and just not worth it.
Saturday, 12 September, is a write-off. Cross-on and onshore winds, 6.6ft and 5.9ft swell, but poor surf conditions. Give it a miss.
Sunday, 13 September, sees a kick in swell to 8.2ft, but the wind is cross-on from the SW at 12 mph, so it’s choppy. The afternoon is a bit better with a cross-shore wind, but it’s still messy.
Monday, 14 September, morning has a light cross-shore breeze from the NNW at 6 mph, with a 7.9ft swell and 14-second period. It’s clean but marginal. The afternoon gets choppy again.
Tuesday, 15 September, has rain showers and a cross-on wind, 5.6ft swell – poor conditions. The afternoon is slightly better but still marginal.
Wednesday, 16 September, morning shows a 5.9ft swell with a 16-second period, cross-off wind from the NE at 12 mph, and clean conditions. Marginal but worth a paddle if you’re desperate.
Now, here’s where it gets wild. Thursday, 17 September, a huge swell arrives. 13.1ft in the morning, 14.8ft in the afternoon, with strong to very strong energy (6579 to 7879). The wind is strong cross-on and onshore, so it’s messy and dangerous. This is for experts only, and even then, it’s risky.
Friday, 18 September, is even bigger. The morning has 14.8ft from the WSW with a 16-second period, and the energy is extreme at

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.
