The Lowdown
G’day, Rusty here, looking at what’s on the cards for Trigg Beach.
Alright mate, we’ve got a solid run of swell on the way, but it’s a bit of a mixed bag with the wind. For the next few days, we’re looking at some proper clean conditions, especially in the mornings. The water’s sitting at 64°F, which is a bit colder than normal for this time of year – so you’ll want the thick rubber.
Right off the bat, Wednesday morning the 12th is a gem. We’ve got a 7ft swell from the SW, a long 15 second period, and glassy conditions with a slight NE breeze at 3 mph. The energy is solid (1983), and it’s going to be clean. This is for experienced surfers though, as it’s a bit on the bigger side.
Thursday morning the 13th is another standout. The swell drops slightly to 7ft from the SW, but the period bumps up to 16 seconds, and you’ve got a light ENE cross-offshore breeze at 3 mph. It’ll be clean as a whistle and the energy is pumping (2299).
Friday the 14th is your pick of the week. Both morning and afternoon look excellent. The morning has a 7ft SW swell, 16 seconds, and a NE cross-off at 6 mph. In the afternoon, the wind dies off completely – glassy as, with a SSE breeze at 3 mph. That afternoon session is going to be magic, with the same 7ft swell. Energy is strong, around 2233.
Saturday the 15th still has clean conditions, especially in the morning with a NE cross-off at 12 mph, but the swell drops to 6ft. The afternoon turns glassy again with WSW wind at 0 mph and a 6ft swell – super clean, but a bit smaller.
Now, from Sunday the 16th onward, things get tricky. The mornings stay cross-off, but the winds pick up, and the quality drops. By Monday the 17th, the wind turns onshore and howls – NW at 19 mph in the morning, then WSW at a nasty 31 mph in the afternoon with a messy 12ft swell. That’s a write-off for paddling, but if you’ve got a kite, the afternoon might be interesting.
Tuesday the 18th sees the swell jump to 13ft from the WSW, but the wind is glassy in the morning with a 3 mph WSW breeze. That’s way too big for Trigg – expert territory only, and honestly, the setup looks more interesting for kite surfing than paddle surfing.
Wednesday the 19th is a washout with onshore winds, and Thursday the 20th has rain showers and strong cross-onshore winds with a 15ft swell – not good. This pattern of big, windy swell continues right through to Sunday the 23rd, with massive energy readings (over 10000 at times). These are expert-only conditions, if that.
There’s a gap of a few days with no solid recommendations, but we do see a return to clean conditions on Monday the 24th of August. Morning session with a 8ft SW swell, 16 seconds, and a light SE cross-offshore at 6 mph. That’s clean, solid surf (2629 energy). Tuesday the 25th morning also looks good – a smaller 5ft SW swell, 13 seconds, with an offsore E breeze at 6 mph. The afternoon that day is a real treat: a 3ft long-period groundswell at 21 seconds, clean with a SSE cross-off. The long period will make it wall up nicely at the point, but it’ll be very inconsistent between sets.
So, the best on offer: Friday the 14th is the standout for overall quality, with both morning and afternoon glassy or clean. Wednesday morning the 12th is also a ripper for a bigger, long-period swell. After that, wait for Monday the 24th and Tuesday the 25th for the next run of clean conditions.
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.
