The Lowdown

G'day, Rusty here. Let's cut through the noise and look at the next couple of weeks for Trigg Beach. It's gonna be a mixed bag, with some proper firecrackers hidden in there, but also plenty of days you'll want to stay on the sand and watch.

The immediate outlook is pretty grim. We've got a big pulse of WSW groundswell arriving Wednesday morning, a solid 10ft but with a cranky 30 km/h NNW cross-onshore and lumpy conditions. The energy is strong, but it's just messy. That afternoon, the wind dies right off to next to nothing and the swell actually bumps up to 12ft with a very long 18-second period. The energy is massive, and while the wind and tide are favorable, this size is just way too big for Trigg. Save that one for the experts or the big-wave crew down the coast. Thursday is a complete write-off with a strong southerly gale shredding it. The swell hangs around 10ft but it's cross-shore and chaotic all day.

We get a bit of relief on Friday. The swell backs off to 6ft and then 5ft with a 13-12 second period, and we finally get some clean conditions with a cross-offshore SE breeze. It's only marginal, though, with moderate energy, so don't expect much push. The real stunner is Saturday. That's the standout of this first week. The morning has a small, clean 3ft WSW groundswell with a super long 19-second period, light offshore E wind, and glassy conditions. It's tiny but perfect. The afternoon is where it's at for the experienced surfer: the swell jumps to 5ft, the period stays at 19 seconds, the wind goes gentle offshore (ESE at 15 km/h) and the energy picks right up. This is the best call for a proper wave. Trigg will be handling that long-period swell well, being a point and reef setup, and it’ll be clean as a whistle. Keep in mind the water temp is 65°F, which is about average for this time of year.

Sunday morning stays excellent for the skilled crowd. Swell builds to 7ft with a strong 18-second period, the energy is cranking, and we have clean conditions with a light NE cross-offshore breeze. That's another cracker. The afternoon, the wind swings onshore and it gets a bit ordinary. Monday is a step down—moderate cross-onshore winds and choppy surf, nothing to write home about. Tuesday looks alright again, with clean conditions and a solid 7ft of WSW groundswell, but the energy is just moderate.

Then we hit a bit of a flat spell. Wednesday and Thursday of the first week have some glassy mornings with clean 5-6ft waves, but they are 'very good' at best, not standouts. The afternoons are ruined by cross-onshore winds. Friday sees the swell push back up to 8ft, but the cross-shore wind makes it messy and marginal.

Now, looking into the second week, things get interesting again. Saturday morning, the 5th, is a standout. The swell is 7ft with a decent period and clean, and we have a light offshore ENE wind. That's going to be fun for the experienced punter. Sunday has a glassy morning, but the week really kicks into gear on Monday the 7th. We get a solid 8ft of WSW groundswell with an 18-second period, light cross-offshore wind, and clean conditions. The energy is pumping. That’s a serious day, but again, it's for experienced surfers only. Tuesday the 8th follows up with a solid 10ft swell and clean conditions in the morning with a light NNE cross-offshore breeze. The energy is right up there. This is another big one.

Then we get a warning. Wednesday the 9th and Thursday the 10th look heavy. The swell is back up to 10ft to 12ft, but the wind turns nasty cross-onshore, making for poor, choppy conditions. The energy will be huge, but it's going to be a washing machine. For a beach and point setup like this, with that much swell and that kind of wind, it might be more interesting for the kitesurfers than for paddle surfing. The Thursday afternoon swell eases to 8ft but the onshore wind still wrecks it.

So, the true standouts over the whole period are Saturday the 29th in the morning and afternoon, and then Monday the 7th and Tuesday the 8th of September for the bigger, cleaner groundswell. The long-period stuff likes the point and reef here, but be warned, those big days can get a bit tricky. Crowds are likely to be a factor on the good days, so get in early.

Rusty, out.

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.
