The Lowdown

G'day, I'm Rusty, and I've got the lowdown on what's coming up for our local stretch.

Alright, we're looking at a solid run of southwest swell over the next couple of weeks, but it's not all smooth sailing. The water temp is sitting at 65°, which is pretty much spot on for this time of year, so nothing out of the ordinary there.

The first decent window opens up on Thursday the 27th. It's a bit of a mixed bag, though. Thursday morning has a 10 ft SW swell rolling in with a 16-second period, which is a long-period groundswell packing a heap of energy. The wind is a fresh cross-shore from the south at 19 mph, so it'll be a bit lumpy and chopped up. Not ideal. Thursday afternoon cleans up nicely with a cross-offshore breeze from the SSE at 16 mph, making the same 10 ft SW swell (15-second period) look a lot better. It's a good pick for experienced surfers looking for an afternoon session.

Friday the 28th sees the swell drop a touch, but the conditions stay clean. The morning has a 6 ft SW swell with a 13-second period and a cross-offshore SE wind at 16 mph. The afternoon is similar with a 5 ft WSW swell, a 12-second period, and the same clean wind. It's not huge, but it's surfable and clean.

Now, the standout for the near term is Saturday the 29th. The morning has a 3 ft WSW swell, but don't let the size fool you. The period is a massive 19 seconds, which is a very long-period groundswell. The energy is still moderate because of the height, but the conditions are what make it special. A moderate offshore breeze from the ESE at 16 mph will have Trigg Beach looking clean and lined up. It's a great morning for a longboard or a funboard.

Sunday the 30th is the real gem. The morning has a 8 ft WSW swell with an 18-second period, pumping out plenty of energy. The wind is a light cross-offshore from the ENE at 6 mph, making for clean, powerful waves. The afternoon is even better with a glassy 8 ft WSW swell (17-second period) and a slight air from the ESE. This is excellent surf for experienced surfers. The size and the long period mean it'll be a bit heavy, so it's not for the faint-hearted.

We hit a bit of a rough patch after that. From Monday the 31st through to Thursday the 3rd of September, the wind turns onshore or cross-onshore, and the quality drops off. The swell is still in the 7 ft to 8 ft range, but the wind messes it up. It's a write-off for decent surfing.

Friday the 4th of September gets a bit wild. An 12 ft W swell with a short 7-second period and a strong cross-onshore wind at 25 mph in the morning is a messy, blown-out situation. The afternoon sees a 16 ft W swell with an 11-second period, but it's still choppy and onshore. This setup is more interesting for kite surfing than paddle surfing.

Into the second week, Saturday the 5th of September morning has a massive 15 ft WSW swell (14-second period) with an offshore wind, but it's just too big for Trigg. The afternoon turns lumpy with a fresh cross-shore.

The next real highlight is on Thursday the 10th of September. The morning has an 8 ft WSW swell with a 16-second period and glassy conditions with a light NNW wind. This is another excellent session for experienced surfers, with clean, powerful lines. The afternoon is a bit more onshore, but the morning is the pick of the day.

After that, it's a bit of a mixed bag with onshore winds and smaller swell, so stay tuned to the forecasts.

So, for the best of the best, I'm calling out the Sunday the 30th morning session for the clean, powerful swell, and the Thursday the 10th morning for the glassy conditions. Keep an eye on the long-range forecasts, but these are looking like the standouts.

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.
