The Lowdown
Alright, this is Rusty checking in, and we've got a solid window of surf ahead. We're looking at Trigg Point. The water is sitting at 63°, which is a bit cooler than we're used to for this time of year.
The main event kicks off Thursday morning, the 20th of August. We've got a big, powerful 8ft groundswell out of the WSW with a very long 16-second period, and the combined energy is cranking at 3594. The wind is glassy out of the ESE. This is serious, clean, powerful surf, but it's definitely one for experienced surfers only. The paddle out will be easier with the long gaps between sets, but the sets themselves will be meaty. It's the best we're going to see.
Friday the 21st is another good call for the experienced crew. You've got a 7ft WSW swell, 15-second period, and a clean offshore breeze from the East. It's still got plenty of punch, and the wave energy is at 2032. Trigg will be looking good.
Saturday morning the 22nd is also worth a look. The swell drops a touch to 6ft from the WSW, but the period is back up to 16 seconds and the wind is a light cross-offshore from the NNE. That should keep the surface glassy and clean, with 1904 energy behind it.
The window gets messy from Saturday afternoon and into Sunday with stronger onshores, but things clean up again for Monday morning the 24th. The wind swings back offshore from the ENE, with a 7ft WSW swell and a 14-second period. It's solid and clean for the experienced surfers again.
We have a bit of a lull on Tuesday the 25th with a drop to 4ft, but Wednesday the 26th brings a massive pulse. The issue is the wind. Wednesday morning is cross-onshore and choppy, and Wednesday afternoon turns into a complete washout with 25 mph winds and heavy rain. This is not for paddling; the setup looks more interesting for kite surfing than paddle surfing.
From Thursday the 27th all the way through to the start of September, the wind is the main problem. We've got a couple of strong swell pulses, but it's blown out with strong cross-shore and onshore winds. The forecast for the first week of September looks like a write-off with powerful but messy swells and strong winds. It's not worth paddling out. Trust me, the wait for the next clean day will be worth it.
This is Rusty, signing off.

Information about the Trigg Point Surf forecast
The above surf forecast table for Trigg Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trigg Point can be found by selecting the local surf guide option on the grey menu. Our Trigg Point 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 Point) 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 Point 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.
