The Lowdown

Alright folks, Rusty here, and I’ve been staring at the charts for Trigg Beach. This is our only spot firing in the 16-day window, so we’re gonna focus on the one place that’s got the goods.

Right off the bat, I gotta tell you, the water is running a bit cooler than usual for this time of year – it’s sitting at 63.1°F, which is about 2.7°F colder than the long-term average. A bit of a nip in the air, so don’t forget the steamer if you’re heading out.

The forecast kicks off this Saturday, the 15th of August. We’ve got a solid WSW swell pushing through at about 6 ft with a 14-second period, and the combined energy is pumping at 1351 – that’s moderate wave energy, but it’s got some grunt. The morning session is looking clean with a cross-off NE breeze at 12 mph, so lineups should be holding shape. But the real standout is Saturday afternoon – the wind drops to a glassy 3 mph from the west, and while the swell drops slightly to about 5.6 ft, it’s still a 14-second period swell. The energy dips a bit to 1111, but glassy conditions on a point break with a decent WSW swell? That’s clean, peeling waves, and you’ll be fighting for your share because crowds are often here. This is the pick of the weekend.

Sunday morning, the 16th, brings a bigger 6.2 ft WSW swell with a very long 16-second period, energy jumping to 1766. But the wind is a fresh NNE at 19 mph, cross-off, so it’s still clean but a bit more blown out. Sunday afternoon is a touch bigger at 6.9 ft, same direction, but the wind drops to 12 mph from the NNE. It’s still surfable, but the energy is climbing to 2067, and the long-period swell can make the sets a bit fat on a beach break – Trigg being a beach and point, the point might handle it better.

Then we hit a rough patch. Monday and Tuesday, the 17th and 18th, the swell gets way too big – Monday morning is 6.9 ft, but by Monday afternoon it’s 11.5 ft with a 17-second period, energy exploding to 5987, and a strong cross-onshore WSW wind at 25 mph. That’s blown out and messy. Tuesday is even bigger – 11.5 ft, 16-second period, energy at 6251 and 6459. The wind is glassy on Tuesday morning (SW 3 mph) and light onshore in the afternoon, but the forecast explicitly says the swell is too big for this break. This is expert territory, and even then, the conditions are questionable. If you’re a kite surfer, Tuesday looks more interesting than paddle surfing.

Wednesday the 19th drops to 8.2 ft, but the wind is cross-onshore, so it’s choppy. The energy is still high at 2691-2983, but it’s not clean. Not recommended.

Now, Thursday the 20th is a hidden gem. The morning is glassy with zero wind, a 9.8 ft WSW swell, 16-second period, and energy of 4136. The forecast says it’s excellent for experienced surfers – and that’s because 9.8 ft is big, pushing into expert territory. But glassy conditions on a big groundswell at a point break? That’s a proper session if you’ve got the skills. The afternoon turns choppy again, so hit the dawn patrol.

Friday the 21st is another solid option. The morning has a 6.9 ft WSW swell, 15-second period, with a light cross-off ESE breeze at 6 mph. Energy is 1860, and it’s clean. The afternoon gets blown out, but the morning is a winner.

The next week starts looking promising. Saturday the 22nd morning has a smaller 4.3 ft swell, but it’s a very long 19-second period from the WSW, with an ENE cross-off breeze at 6 mph. The energy is 2296 – that’s a lot of juice for a small wave, thanks to the long period. This is a classic groundswell that will wrap around the point beautifully. Sunday the 23rd is glassy in the morning, 6.2 ft SW swell, 16-second period, energy 1845 – another clean, punchy option.

The last few days of the forecast (24th to 30th) see the swell dropping and the wind turning onshore or cross-shore, with lower energy levels (mostly under 1000). The 28th of August morning has a glassy 6.6 ft WSW swell, 18-second period, energy 2492 – that’s a standout in the second week, but it’s a long way out, so take it with a grain of salt. By the 30th, it’s back to big, messy, onshore conditions.

So, for the whole period, the best on offer is Saturday afternoon, August 15th – glassy, clean, 5.6 ft WSW swell at 14 seconds. That’s the one. Thursday morning, August 20th is a close second for the experienced crew, with big, glassy waves. The second week has

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.
