The Lowdown

Alright, mates, Rusty here. Let’s cut through the noise and see what the next couple of weeks are all about. It's a bit of a mixed bag, so let's take it day by day.

The immediate forecast is pretty mediocre, with a lot of onshore breeze mushing up the surf. We’ve got some size, but it's not going to be clean. The real standout window looks like it’s shaping up for the end of the first week and into the start of the next, but we’ve got some slop to get through to get there.

Tuesday, August 4th starts things off with around 6.9ft of swell from the west-southwest, but a moderate onshore breeze is going to chop it all up. It’s not going to be pretty. The water is sitting at 63.3°F, which is a bit colder than normal for this time of year, so you’ll want the full winter rubber.

Wednesday, August 5th is a bit better. The wind drops right out to a light breeze, and the swell is still pushing 8.2ft from the west-southwest. The surf is a touch cleaner, but still pretty average. There's a moderate amount of energy there, but it's not world-class.

Thursday, August 6th sees the swell up to 9.8ft, but again, a light cross-onshore wind is just keeping it from being truly clean. It's a bit of a struggle. The energy is still moderate, just not that exciting.

Now, Friday, August 7th is a straight-up write-off. A fresh onshore breeze is whipping it up into a messy, rainy mess. With swell at 9.8ft and onshore winds of 30 km/h, it’s going to be a washing machine out there. You can give this one a miss.

Saturday, August 8th brings in a serious amount of swell, hitting a solid 13.1ft. The wind is cross-shore, which mixes things up, but honestly, this is way too big for this spot. The combined energy is massive. This is purely for the experienced crew, and even then, it's looking heavy and dangerous. Not my idea of a fun session.

Sunday, August 9th settles down to 9.8ft, with a light onshore wind in the morning, but it gets blown out by a moderate onshore breeze in the afternoon. It's still not great, just kind of average and lumpy.

But then we get to the good stuff.

Monday, August 10th is your standout morning. The swell drops to a more manageable 7.9ft, and the wind swings around to a light cross-offshore from the southeast. The surf is clean, and the energy is moderate. This is the pick of the week, especially for the more experienced surfers. The direction is still from the southwest, which is solid for Trigg. It's not huge, but it'll be clean and have some power.

The rest of the week after that is a bit hit-or-miss, with light winds but generally messy cross-onshore conditions. The swell stays in the 6.9ft to 7.9ft range, so there’s size, but the wind is always just a bit on it.

Then we get to the long-range outlook for the second week.

Friday, August 14th the swell jumps back up to 9.8ft, and it looks like the wind might be a bit lighter. It’s a long way out, so we’ll call it promising but not locked in. However, the swell direction is good and the period is a solid 18 seconds, so there’s some real groundswell energy in it. There’s plenty of push.

Saturday, August 15th is similar, but the swell just keeps getting bigger, hitting 11.5ft. This looks set to be too big for this break again, even with good winds. It's going to be a big, powerful beast of a day.

Sunday, August 16th the swell is still up around 9.8ft, but unfortunately the wind turns onshore again, making it messy.

Then the end of the run sees more big swells, but they’re all coasting in the 11.5ft to 14.8ft range. The winds are mostly light, but the size will be intimidating for most and likely too big for this spot. The energy levels are strong, but it's not the sort of day you want to be paddling out at Trigg unless you're on a gun and know the place inside out.

So, in summary: There are a couple of decent windows early next week, but the standout is clearly Monday morning, August 10th. It's clean, has a solid southwest swell, and won't be a washing machine.

The long-range stuff from the 14th onward is promising, but it’s a week away and looks like it’ll be too big, so approach with caution. The rest of the time, you’re looking at average waves with iffy winds.

Stay safe out there.

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.
