The Lowdown
G’day, Rusty here. Let’s break down what Trigg Beach is offering over the next couple weeks.
We start off Friday the 28th of August feeling a bit average. Morning swell is around 6 ft from the SW with a 13-second period and moderate energy (1173). Wind’s cross-off from the SE at 15 mph, so it’s clean but the conditions are marginal. Water temp is 65°, about normal for the season. The arvo stays similar.
Saturday the 29th of August is much better, especially the morning. Swell drops to 3 ft but it’s a long 19-second groundswell from the WSW with moderate energy (910). Wind goes offshore from the ESE at 15 mph, giving clean waves. That’s a good session. Afternoon swell pushes to 6 ft with energy jumping to 1944 – still cross-off and clean.
Sunday the 30th of August is a standout. Morning is excellent – 8 ft of WSW swell, 18-second period, and very strong wave energy (3200). Wind is almost nothing from the NE at 3 mph – glassy and clean. This one’s for the experienced crew – size and power on offer. Trigg’s a beach and point, so hunt the point for the best shape.
Monday the 31st and Tuesday bring onshore and cross-shore winds, quality drops. Swell holds around 7 ft but it’s messy and choppy – not worth it.
From Wednesday the 2nd of September through the end of the first week it’s mostly average. Thursday the 3rd has some cleaner moments with cross-shore winds and 8 ft swell, but it’s only marginal. Friday and Saturday the 5th are blown out with strong to near gale winds – kites will be loving it, surfers not so much. Energy hits 3201 Saturday arvo but wind ruins it.
We hit a lull Monday the 7th of September. Morning has a tiny 3 ft groundswell from the WSW, but it’s glassy – dead calm. Great for a longboard session.
Tuesday the 8th of September morning is a real gem. Swell is 4 ft from the WSW with a 14-second period and moderate energy (1074), but wind is completely glassy at 0 mph. Perfect conditions.
Wednesday the 9th of September morning sees 10 ft WSW swell with a 16-second period and very strong energy (4504), but cross-shore wind at 12 mph gives messy chop. Afternoon energy hits 7871 but onshore – huge but ugly.
Thursday the 10th and Friday the 11th of September are massive. 16 ft on Thursday morning with energy at 13416 – extreme. With 18 mph cross-onshore wind, it’s lumpy and blown. Friday’s still too big at 12 ft for Trigg, even with light wind.
Saturday the 12th of September morning is another standout. Swell is 8 ft from the WSW with a 15-second period, strong energy (2381), and glassy conditions – wind barely 3 mph. Excellent for experienced surfers, clean and powerful.
Best of the whole outlook is Sunday the 30th of August morning – big clean swell with glassy conditions. For a quieter, long-period session, Tuesday the 8th of September morning with that glassy 4 ft will be a treat.
Stay safe on the bigger days.
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.
