The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu for Trigg Beach.
First up, the water’s sitting at 64°F which is a bit colder than what we usually get this time of year. Nothing freaky, but you’ll want that extra rubber.
The forecast kicks off with a bit of a sour note. The first couple of days are a write-off. Saturday afternoon has some 8ft swell from the WSW, but with a 15 mph NW wind putting a chop on it, it’s just messy. No go. Sunday and Monday are a bit of a tease – the swell sticks around 8ft with a decent period, but the wind is cross-off or clean, and the models are hedging their bets, calling it marginal. The waves will be there, but the quality isn't locking in yet.
The first real standout comes on Tuesday the 8th. The morning session is your best bet. We’ve got a clean 8ft swell from the WSW, with a 17-second period – that’s proper groundswell energy. The wind is offshore from the ESE at 15 mph, which should groom those lines beautifully. The combined energy is a solid 4060 (moderate to strong). This is a classic Trigg point setup when it’s clean. For experienced surfers, this is where it’s at. The sets will be a bit longer between them due to that long period, making the paddle out easier, but at 8ft, it’s pushing into expert territory.
Wednesday the 9th afternoon is also a beauty. The swell drops slightly to 7ft, but the wind goes full offshore from the E at 12 mph. The period is 15 seconds, and the energy is still strong at 2144. It’s clean, it’s peeling, and for the experienced crew, it’s a real treat.
After that, the swell backs off a bit into the 4ft to 5ft range towards the end of the first week, with lighter winds but some tricky cross-off or onshore conditions. Nothing to get too excited about.
Then we hit a bit of a lull. The second week starts with a few poor days of onshore junk and some rain showers. The swell picks up again around Monday the 14th, with 8ft swell and clean cross-off wind from the ENE. Tuesday the 15th is a bit of a mixed bag, but look at Wednesday the 16th morning. Glassy. Zero wind. A 7ft WSW swell with a 15-second period. The energy is 1811 (moderate). That’s as good as it gets for a mid-week dawny. The ocean will be like a mirror. For experienced surfers, that’s the pick of the second week.
The tail end of the forecast gets gnarly but ugly. From the 18th onwards, we’re looking at big 10ft to 12ft swell, but it’s all onshore wind. At that size and with a beach-and-point setup, it’s going to be a washing machine. That’s more of a kite-surfing show than a paddle-in session. Not worth it for the surfer.
So, the standout calls: Tuesday morning the 8th and Wednesday morning the 16th. Both offer clean, strong, long-period groundswell with offshore or glassy conditions. Go get it.
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.
