The Lowdown

Alright, Rusty here, let’s break down what’s happening at Trigg Beach over the next stretch.

First few days are a bit of a mixed bag, nothing to rush out for until later in the window. The pattern is all over the place, with plenty of swell but the wind and size aren’t cooperating. We’ve got a few clean windows, but the real standout is a couple of sessions that’ll be worth the paddle.

Right now, on Saturday the 1st, there’s a 2.4m (8ft) SW groundswell rolling in with a very long period of 15 seconds, carrying strong energy (2560). The water is 63°F, which is a bit colder than normal for this time of year. The morning has a cross-off SSE breeze at 12 mph, so it’s clean, but the report says it’s marginal. The afternoon swings to a cross wind, making it a bit sloppy. Not the best start.

Sunday the 2nd is a better bet. The morning has a 2.1m (7ft) WSW swell, still good at 14 seconds, with a cross-off ENE breeze of 16 mph. It’s clean, but the real gem is Sunday afternoon. You’ve got a 2.0m (7ft) WSW swell, 14-second period, moderate energy (1390), and a light cross-off NE breeze at 6 mph. That’s clean, lined up, and the report says excellent conditions for experienced surfers. That’s your first real highlight – a solid afternoon session, but remember, 2.0m is getting up there, so it’s for the crew who know what they’re doing.

Monday the 3rd and Tuesday the 4th are a write-off. Monday gets a lumpy cross-chop from a NW wind, and Tuesday sees a massive 19-second period groundswell up to 2.5m (8ft) but with onshore winds, making it a mess. Combined energy is through the roof (4225 on Tuesday afternoon), but it’s onshore and ugly. Leave it for the kites, not the paddles.

Wednesday the 5th is where it gets hairy. The morning has a 2.4m (8ft) WSW swell, but by the afternoon, it’s a 3.5m (12ft) monster with a 16-second period, and the energy is massive (5485). The wind is actually light, but the report says the swell is too big for this break. That’s expert territory or maybe just watching from the beach. Same story for Thursday the 6th – 3.0m (10ft) sets, but onshore winds blow it out.

The week from the 8th to the 10th is a complete wipeout. We’re talking 5.0m (16ft) to 6.0m (20ft) swells with near gale-force winds. Zero chance of a decent wave. The energy numbers are insane (up to 27126 on the 9th), but it’s all just raw power and wind. Not for us.

Now, after the storm passes, we get a nice reset. Tuesday the 11th has a cleaner 1.8m (6ft) SW swell with a 13-second period, cross-off SSE wind at 12 mph. It’s clean, but the real standout is Wednesday the 12th. That morning, you’ve got a 1.5m (5ft) SW swell with a long 17-second period, light ENE breeze at 6 mph, and the report says “expect very good surf conditions.” The afternoon is even better – 1.4m (5ft) SW swell, 16-second period, and a glassy offshore E wind at 3 mph. That’s the pick of the whole forecast. Clean, lined up, and just the right size for a fun session. Combined energy is moderate (994), so it’s not a beast, but it’ll be quality.

The following stretch from the 13th to the 15th has more swell, but it’s on the bigger side again. Thursday the 13th and Friday the 14th have 2.2m (7ft) to 2.5m (8ft) WSW groundswells with long periods (17-19 seconds) and clean cross-off winds. The report says “excellent for experienced surfers” on Friday the 14th morning. That’s a solid backup option, but the 12th is still the best day.

The final weekend, the 15th and 16th, goes back to massive size – 3.5m (12ft) to 4.5m (15ft) – with cross onshore winds and too big for the break. Not our day.

So, here’s the takeaway: if you’re looking for the best wave, circle Wednesday the 12th, especially the afternoon glass-off. Sunday the 2nd afternoon is a close second. The rest of the time, it’s either too small, too big, or too windy. Stick to those windows and you’ll get a good one.

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.
