The Lowdown

Alright, Rusty here. Let’s get into it.

Alright, the outlook for Trigg Beach is a bit of a mixed bag over the next couple of weeks. We’ve got some solid windows of clean, offshore surf, but also some periods that are just a write-off. The water temp is sitting about average for the time of year, so nothing wild there.

The best of the bunch kicks off right away. Wednesday the 22nd through Thursday the 23rd is looking like the real standout. Wednesday morning we’ve got a 5ft SW swell with a 13-second period, coming in with a gentle ESE offshore breeze. That’s clean, lined-up surf with moderate energy (832). By Wednesday afternoon, the swell bumps up to 5ft from the SW, the period stretches to a very long 16 seconds, and the energy jumps to 1622. The wind stays offshore, glassy. This is the kind of session you call in sick for. The longer period means better shaped waves, but watch out for them lining up a bit too straight on the beach – it’ll be better on the point. The crowds are likely here, but for waves like this, you’ll paddle out anyway.

Thursday morning the 23rd holds, with a 5ft SW swell, 14-second period, and a clean ENE offshore breeze. Energy is still moderate at 902. The afternoon stays clean too, with a 5ft SW swell. That’s two full days of quality.

Friday the 24th drops off a bit. The swell backs down to 3ft, and the wind turns cross-offshore, so it’s clean but weaker. Saturday the 25th is a write-off – onshore winds and choppy conditions. Sunday the 26th is even worse, with a fresh cross-onshore wind and a 8ft SW swell on a short 8-second period, so it’s lumpy and messy. The energy is strong at 913 but it’s not for paddling.

We get a brief reprieve on Monday morning the 27th. A 7ft WSW swell, 13-second period, with a light SE cross-offshore breeze. Clean, moderate energy (1309). That’s a good session, but get it in the morning because the afternoon turns cross-onshore and choppy.

Tuesday the 28th is another good one. The morning is a bit borderline with a 5ft SW swell and moderate ENE cross-offshore wind, but the afternoon is where it’s at. That same 5ft swell, 14-second period, but with a light NE breeze and energy at 1025. Clean, rideable.

After that, the outlook gets grim. From Wednesday the 29th onward, we’ve got a long stretch of poor conditions. The wind swings onshore and stays there, bringing rain, thunderstorms, and gale-force winds. The swell gets huge – we’re talking 12ft to 20ft from the 31st of July through to the 6th of August. The energy numbers are massive (over 5000, hitting 23286 on the 2nd of August), but with the wind howling onshore, it’s a complete mess. This is not for paddle surfing. If you’re into kiting, the setup from the 31st of July through the 3rd of August might be interesting, but for a surfer, stay home.

The 4th and 5th of August offer a slight drop in size, but the wind is still messy and the swell is mixed. Not worth the paddle.

So, to sum it up: Wednesday 22nd and Thursday 23rd are the clear standouts. Get in the water early and often. After that, it’s a waiting game. The second week looks big and windy, but not useless for other sports. Forecasts can change, so keep an eye on it.

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.
