The Lowdown

G’day, I’m Rusty. Let’s have a look at what’s coming down the line for Trigg Beach over the next couple of weeks.

Right now there’s a bit of a slow start, but things get going from Wednesday the 29th of July. A solid, long-period SW groundswell is rolling in at 5 feet with a 17-second period. That’s proper energy—very long-period stuff, which means the waves will have real push and shape, but those long gaps between sets will make paddling out a bit easier if you’re patient. The combined energy is strong at 1823. Wind is a light NE cross-off, keeping things clean. The water is sitting at 63°, which is a fair bit colder than usual—about 3°F below normal, so you’ll want a good wetsuit. This is the pick of the early window, but it’s only for experienced surfers; at 5 feet and this period, the sets will have some real grunt.

The next few days are messy. Thursday the 30th and Friday the 31st see a drop in surf quality—wind swings onshore and the consistency drops. There’s swell, but it’s choppy and cross-on, so not worth paddling out for.

Saturday the 1st of August looks better, especially in the morning. A 8-foot SW groundswell, 15-second period, with a clean SSE cross-off. Combined energy is strong at 2392. This is intermediate-sized, but the wind is fresh at 12 mph, so it’ll be a bit of a workout. Sunday the 2nd afternoon is a standout: the swell drops a touch to 7 feet from the WSW, 13-second period, and the wind goes glassy off the ENE at just 3 mph. Waves will be clean and fun for experienced surfers again. Energy is moderate at 1370.

Monday the 3rd morning is absolutely glassy—wind calm, swell 5 feet from the WSW with a 14-second period. Energy at 921 (moderate). This is the best on offer for a clean, user-friendly session. But come Tuesday the 4th morning, we get a serious pulse: 8 feet from the WSW with an 18-second period—very long-period groundswell. Combined energy is through the roof at 3790. Glassy conditions again. This is massive, pulsing surf that’s only for experts.

From Wednesday the 5th into the second week, it gets lumpy and windy. Wednesday afternoon is onshore WSW at 9 mph, and Thursday the 6th is a write-off with strong onshore winds up to 19 mph—choppy and poor. Friday the 7th cleans up slightly with a 8-foot SW swell, 14-second period, and a cross-off southerly, but it’s still marginal.

Then the big stuff hits. Saturday the 8th of August sees a huge 13-foot to 18-foot WSW swell with onshore gales—22 mph—and combined energy hitting 12030. That’s dangerous, not for surfing. Sunday the 9th calms down wind-wise with glassy conditions in the morning, but the swell is still 15 feet—way too big for this break. Only for the crazy crew.

The rest of the second week stays big and messy through to Tuesday the 11th, with gale-force winds and rain. By Wednesday the 12th, it starts to settle with a 6-foot SW swell and clean cross-off winds. Then Thursday the 13th morning looks really good: 7-foot WSW swell, 15-second period, glassy conditions again with an ENE breeze at 3 mph. Combined energy is moderate at 1857, and it’s excellent for experienced surfers.

So overall, the real standouts are the glassy Wednesday morning on the 3rd of August and that massive but expert-only Tuesday the 4th. The rest is a mix of big, windy swells and clean windows for the bold. Keep an eye on that Thursday the 13th—it’s shaping up as a nice clean session after the storm.

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.
