The Lowdown

Alright folks, Rusty here. Let’s look at what’s cooking at Trigg Beach for the next couple of weeks.

First up, we get a bit of a slow start. Monday the 20th of July has some 5ft swell from the WSW, but the wind is cross-onshore and messy. The water’s running about 64°, which is a bit colder than usual for this time of year – you’ll want a good wetsuit.

The real highlight is Tuesday morning, the 21st of July. The wind goes light offshore from the ENE, and we’ve got a clean 5ft of SW groundswell with a 14-second period. The energy is moderate (816), and that cross-off breeze will have Trigg looking like a picture. It’s the best call of the week.

Wednesday the 22nd of July is also a cracker. The morning starts with a light offshore from the ESE and 5ft of SW swell. But the afternoon is the real deal – the wind is light offshore from the east, and the swell bumps up to 6ft from the SW with a very long 16-second period. The energy jumps to 1724, and the conditions are described as excellent for experienced surfers. That long period means the sets will have real power. The point might offer a better line than the beach.

Thursday the 23rd of July has a moderate offshore breeze and 5ft of SW swell, still clean. The swell fades through the end of the week. Friday the 24th and Saturday the 25th offer smaller 3ft to 4ft waves with clean winds. Fun for a longboard, but nothing massive.

Then the wheels fall off. From Sunday the 26th of July through the end of the month, the wind turns onshore and strong. The swell is there, even getting up to 7ft on Monday the 27th, but it’s lumpy, blown-out junk. A week to skip.

Early August, there’s a big, messy event on Sunday the 2nd with 8ft of short-period WNW swell and cross-onshore wind. The following Monday the 3rd of August sees a huge 13ft swell from the west, but it’s raining and onshore – that’s kite surfing, not paddle surfing.

The biggest event of the entire forecast is Tuesday the 4th of August. We’re looking at a massive 15ft swell from the WSW with a 15-second period. The combined energy is a staggering 10718. The wind is light and cross-shore, which is rare. But the forecast says it’s too big for this break. This is expert-only, and even then, it’s going to be a washing machine. Huge, powerful, and dangerous.

So, the short story: grab Tuesday morning the 21st and Wednesday afternoon the 22nd of July. The rest is either small, blown out, or way too big. That Tuesday the 4th of August is a monster, but only for the bravest.

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.
