The Lowdown

Right, let's have a look at Trigg Beach for the next couple of weeks. It’s a classic beach-and-point set-up, and she’s fairly consistent, but this stretch of forecasts is a bit of a mixed bag. We’ve got plenty of energy in the water, but the wind and the size are going to be the real players here.

First up, the water temp is sitting at 63°F, which is a bit colder than normal for this time of year, so you’ll want the hood and gloves. Now, the good stuff. The real standout is Wednesday morning the 5th. We’ve got a solid 8ft of WSW groundswell rolling in with a long 16-second period, and the energy is strong. The wind is a light offshore from the NNE, making things clean. This is proper, powerful surf for experienced surfers. It’s a touch big for the weekend warriors, but for those who know what they’re doing on a bigger board, it’s going to be firing.

The next few days are where things get tricky. The swell stays big, even pushing 10ft, but the wind swings onshore and gets messy. Thursday through to Saturday brings in stronger winds, rain, and a lot of chop. We’re looking at combined energy readings well into the thousands, but the quality just isn't there. This is a case of plenty of power, but no form. Kite surfers might be eyeing this up, but for paddle surfing, it’s a write-off.

Sunday the 9th is interesting. The swell is still a hefty 12ft with a 17-second period, and the wind is light from the north, which is a cross-shore. The call says it’s just too big for the break. It’s a fine line, but when it’s that size, it can get a bit unruly. The following Monday and Tuesday keep things big and messy, with fresh cross-shore winds and lumpy conditions. Not worth paddling out for.

Then we get to the real window. Wednesday the 12th through to Friday the 14th is where I'd be pointing my board. The swell eases to a more manageable 8ft and 7ft, still from the SW with a long period, and the energy remains moderate. The wind is offshore or light cross-offshore from the east-northeast in the mornings, leaving the surf clean and well-shaped. This is classic Trigg. The mornings are going to be the go, with the afternoons getting a bit of cross-shore wobble.

Saturday the 15th is another gem for the early crew. The swell drops to 6ft, but the wind goes completely glassy. It’s a fantastic morning for a longboard or a mid-length.

After that, the second week is a bit more up and down. Sunday the 16th starts off average, but then Monday the 17th sees the swell push back up to 10ft with a long 17-second period. The wind is onshore, so it’s not great. Then we get back to it on Tuesday the 18th with a clean 8ft morning and a light offshore breeze. That's another good window.

The tail end of the period, from Wednesday the 19th onwards, looks like it’s going to get blown out. Strong onshore winds and rain move in, and while the swell stays around the 7ft mark, the conditions will be poor. We’re looking at fresh to strong cross-onshore winds and messy, lumpy surf. A blank run to end it off.

So, if you’re planning, the two real standouts are the Wednesday morning the 5th for the big-wave crew, and the clear mornings of the 12th, 13th, and 14th for the best combination of size, power, and clean conditions. The 15th is the one for the loggers. Keep an eye on that second week, it’s promising but we’ll see how it lines up.

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.
