The Lowdown

Alright folks, Rusty here with a look at the next couple of weeks at Trigg Beach. We’ve got a bit of a mixed bag, but there are some real gems hidden in there if you’re patient.

The pattern starts off a little shaky, with a few days of waiting before we get into the good stuff. The water temp is sitting at 64°, which is about average for this time of year, so no need to dig out the thickest rubber just yet.

Thursday 10th starts the period, but it’s nothing to get excited about. We’ve got a 5ft swell from the WSW with a long 15-second period, giving a moderate energy (1180). The wind is a cross-off from the ENE at 16 mph, which keeps things clean, but the overall quality is just marginal. The afternoon improves a touch with a 5ft swell and offshore wind, making it clean, but it’s still not the standout.

Friday 11th morning is similar, with a 5ft WSW swell and a clean cross-off breeze, but the afternoon sees the wind swing onshore, making things choppy. Saturday and Sunday are write-offs with onshore winds and messy conditions on a 6ft to 7ft swell.

Now, here’s where it gets good. The real standout is Monday 14th morning. The swell drops to a clean 8ft from the WSW, with a 14-second period, and the wind goes light offshore from the east at 6 mph. The energy is strong (2358). This is excellent surf for experienced surfers, and the offshore wind will have those lines peeling nicely. The crowd factor is listed as "often" here, so expect a few out there, but it’ll be worth it.

Tuesday 15th morning is another beauty. The swell is 8ft from the WSW, and the wind is virtually nothing from the southeast at 3 mph, making it glassy and clean. This is top-tier, with strong energy (2148). Another one for the experienced crew.

We then hit a dry patch from Wednesday 16th through to Friday 18th, with the swell dropping and the wind turning onshore and messy. The 17th and 18th are particularly poor, with fresh onshore winds making it lumpy and choppy. Not worth paddling out.

Saturday 19th is a big one, but it’s a problem. The morning swell is a massive 13ft from the west, and the afternoon is 15ft from the WSW. The energy is off the charts (5111 and 7924). This is way too big for Trigg Beach, and it’s listed as too big for the break. This setup looks more interesting for kite surfing than paddle surfing. Leave it for the tow crew.

The next standout is Sunday 20th morning. The wind is glassy – zero from the ENE – and the swell is a much more manageable 7ft from the WSW. The energy is moderate (1502). This is perfect conditions for experienced surfers. The glassy conditions will be a dream.

Monday 21st morning is another huge one at 12ft from the WSW (7033 energy), but again, too big for the break. The afternoon is a messy onshore 10ft.

Tuesday 22nd morning brings it back into the sweet spot. An 8ft swell from the WSW with a 15-second period, and a light cross-off breeze from the SSE at 6 mph. The energy is strong (3241). This is excellent for experienced surfers, with clean conditions.

The final run of good surf comes from Thursday 24th through to Friday 25th morning. Thursday 24th is a cracker: a 6ft swell from the SW with a 16-second period, and a solid offshore wind from the ESE at 12 mph. The energy is moderate (1667 and 1892). This is clean, moderate offshore, and will be a fun session. Friday 25th morning is similar, with a 6ft WSW swell and a light cross-off breeze, keeping it clean.

A quick note on the big swells we saw: they’re all long-period groundswells (14-17 seconds), and those long periods will make them break a bit straight at Trigg’s beach break, but the points and reefs will handle them much better.

Overall, the best on offer is Monday 14th morning and Tuesday 15th morning for the perfect combination of size, wind, and strong energy. The later part of the second week, specifically Thursday 24th and Friday 25th morning, is also a solid, reliable option, but with slightly smaller waves. The glassy Sunday 20th is a treat, too.

Rusty, signing off.

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.
