The Lowdown

Alright, Rusty here. Let's talk about Trigg Beach. We've got a wild ride ahead over the next couple of weeks, with some proper size and a few windows of absolute magic if you time it right.

Right off the bat, the water temp is sitting at 64°, which is a bit colder than normal for this time of year, so you'll want that 4/3 or maybe even a hood for the dawn patrols.

The big story is the swell. It’s pumping. For the first week, we're looking at a solid, long-period groundswell from the WSW. This is serious, deep ocean energy, with combined energy readings in the thousands and even hitting four digits (6270) on Sunday morning. That tells you there’s a lot of power in the water. This is not a beginner's playground. Anything over 8 ft is expert territory, and we’ve got waves hitting 12 ft to 13 ft.

Sunday the 9th kicks off with an 12 ft WSW swell. Morning has some clouds and a light cross-on from the NW. The swell is just too big for the break to handle properly, but the wind and tide are favorable. Honestly, for most of us, it’s a day to watch from the rocks. By afternoon, the wind picks up onshore and it gets messy. Monday the 10th is a write-off with strong winds and poor conditions.

We get a bit of a reprieve Tuesday the 11th with a 10 ft SW swell, but the wind stays cross or cross-on, keeping things choppy. The energy is still massive (5304). Wednesday the 12th drops a little to 7 ft, but the wind is light and variable, offering a slight chance of a clean wave in the morning if you pick your bank.

Now, Thursday the 13th is where you set the alarm. Morning is glassy, with a clean 7 ft SW groundswell and an easterly breeze. The combined energy is still solid (2146), and the report says it's excellent for experienced surfers. This is the standout of the first week. The swell direction (SW) matches the optimum for Trigg, and glassy conditions will turn this beach and point into something special. Expect a crowd though – places like this don't stay secret.

Friday the 14th is another good one, with clean conditions in the morning and afternoon. A 7 ft SW swell with light offshore breezes. Beautiful.

After a solid week of swell, Saturday the 15th sees the size drop to 6 ft, but the Saturday afternoon session looks very good with glassy conditions. Sunday the 16th gets windy again in the afternoon.

Then, hold onto your board. From Monday the 17th through Wednesday the 19th, we get another pulse of massive swell. We're talking 12 ft to 13 ft again from the WSW with extreme energy (8511). The forecasts all say the swell is too big for this break. This is big-wave territory for experts only, and even then, the wind is messy. The setup might look more interesting for the kite crew than paddle surfing on those days.

The second week calms down a bit. Thursday the 20th looks promising with an 8 ft WSW swell and a clean offshore breeze in the morning. That’s a great option. Friday the 21st drops to a clean 6 ft with offshore wind – much more user-friendly. Saturday the 22nd afternoon has a clean 7 ft SW swell with light wind. The final days (23rd and 24th) get blown out or too small.

So, to wrap it up: the clear standout is Thursday morning, the 13th of August at Trigg Beach. That glassy 7 ft groundswell from the southwest with offshore wind is the pick of the fortnight for experienced surfers. The long-range calls for Thursday the 20th and Friday the 21st also look promising, but with less certainty. Get out there and score.

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.
