The Lowdown

G'day, this is Rusty. We've got a bit of a mixed bag on our hands for Trigg Beach over the next couple of weeks. Don't get too excited straight away, because the first few days are pretty average. The water temp is about what you'd expect for this time of year, so no surprises there.

The forecast starts with a small window of opportunity, but it's nothing to write home about. Monday the 31st of August, we've got a 7ft WSW swell rolling in with a very long 17-second period, which is proper groundswell. The problem is a cross-on wind from the WNW at 9 mph, making it fairly choppy. The combined energy is moderate at 3109, but the wind just kills it. It's a "marginal" call, and honestly, it's a pass for me.

We've got a bit of a dry spell for the next few days. Tuesday, Wednesday, and Thursday are all "marginal" at best, with similar sized swell but the wind's either cross-shore or cross-on, and it just doesn't clean up. Combined energy drops right down to the 1300-1800 range, so the waves are weak and messy. Friday the 4th of September, the swell bumps up to 10ft in the afternoon, still from the WSW, but the wind is cross-on from the SSW and the surf is described as "fairly choppy." It's not great.

The weekend is a write-off. Saturday the 5th of September, the wind is howling from the NW at 15-18 mph, making it lumpy and poor. Sunday the 6th, similar story with a strong S wind. If you're a kite surfer, this setup might look interesting, but for a paddle, it's a no-go.

Now, here's where it gets interesting. Monday the 7th of September, we see a 10ft WSW swell with a 16-second period, but the wind is onshore from the WSW at 9 mph. The energy is ramping up to 4006, but it's still "marginal." The real standout is Tuesday the 8th of September. Tuesday morning, the swell jumps to 12ft from the WSW with a very long 18-second period, and the combined energy is a massive 7020. The wind is virtually nothing from the West at 3 mph, and it's described as "slight air." The forecast notes say the wind and tide are favorable, but the swell is too big for this break. That's a big call – 12ft is expert territory, and with that long period, it's going to be a challenge. For experienced surfers only, and even then, it's a beast.

The following week sees a few more "marginal" days. Wednesday the 9th to Friday the 11th, the swell sits around 8ft to 10ft, but the wind is shifting around, keeping things cross-shore or onshore. The energy is still moderate, between 2600 and 3200. Saturday the 12th of September, the swell peaks again at 15ft from the WSW with a 16-second period, and the combined energy is a massive 9403. The wind is glassy from the SW at 3 mph in the morning, which is perfect, but again, the forecast says the swell is too big for the break. 15ft is a monster, and only for the absolute elite. Sunday the 13th, still 12ft, still too big for most.

The most promising session for the average surfer is actually right at the end of the forecast period. Tuesday the 15th of September, we get a 7ft WSW swell with a 15-second period, and the wind is glassy from the West at 3 mph. The combined energy is 1716, which is moderate, but the conditions are described as "excellent surf conditions for experienced surfers." That's the best call we've got in the whole 16 days. The swell direction is bang on the optimum from the WSW, and clean glassy conditions. It's a fair way out, so treat it as promising but not locked in.

So, to sum it up: the best on offer is the glassy Tuesday morning the 15th of September at Trigg Beach. The swell will be 7ft from the WSW, and with no wind, it'll be clean. For the adrenaline junkies, the massive swells on the 8th and 12th are there, but only if you're a real charger. The rest of the period is a write-off, with a lot of marginal and poor conditions. Keep an eye on the end of the run.

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.

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.
