The Lowdown

Alright, let’s get into it. We’ve got a proper stretch of Indian Ocean groundswell lining up at Trigg, but it’s not gonna be a straight run of glory. The first couple of days are a write-off – Monday the 10th is messy and blown out with rain. Winds are howling, swell is all over the place, and the ocean’s got no shape. Not worth the paddle.

Tuesday the 11th settles down a bit, but it’s still marginal. That solid 10ft of SW swell (combined energy 5370) has some push, but the cross-shore wind is chopping it up. You’ll get waves, but they’ll be hard work. Surfable for the keen, but nothing special.

Then we get our first real window. Thursday the 13th morning is the standout for the near term. The wind goes glassy, that 7ft SW swell is still rolling in, and the period is a solid 15 seconds. This is clean, lined-up Trigg. Water temp is sitting at 64° which is a touch colder than normal for this time of year, so throw on the booties if you’re soft. It’s not huge, but it’s clean and the banks should hold. The afternoon loses a bit of shine as the wind turns cross-shore.

Friday the 14th is your second pick early in the week. A morning cross-offshore breeze with 7ft of SW swell (16s period) is going to make for some proper, clean walls. The water’s still around that same temp, but the surf is good. This is the kind of day where you don’t want to be late for work.

Saturday the 15th drops off a little in size, but Saturday afternoon is pure glass. 6ft of WSW swell with no wind at all – that’s a fun, manageable size for a board you don’t mind putting a few scratches on. It won’t be epic, but it’ll be a lovely, uncrowded-feeling arvo if the tide lines up.

Sunday the 16th is a bit of a mixed bag. Morning is clean but small (5ft). The afternoon picks back up to 7ft with that same WSW direction and a 15-second period, and the wind stays cross-off. It’s another solid session, if a bit inconsistent.

Now, here’s where the forecast gets interesting and you need to mark your calendar. Monday the 17th sees a new pulse of energy, but it’s messy onshore in the morning. The afternoon cleans up slightly, but the swell jumps to 10ft with 17 seconds of period. That’s a lot of water moving.

The real power surge hits Wednesday the 19th, but don’t get too excited – it comes with a strong cross-onshore wind and a massive 18ft of WSW swell. That’s way over the head and just lumpy, wind-whipped chaos. The combined energy is at 10414, which is pumping, but it’s only for the experienced and even then, the conditions will be brutal. This day is for the spectators or the crazy tow crew.

Thursday the 20th is still messy with strong winds and 10ft of swell – again, not good for Trigg. It’s not until Friday the 21st that things settle. The swell is still 10ft, but the wind swings cross-offshore and it cleans up. The period is a solid 16 seconds, so there’s some serious power. This is a big, clean, powerful day. It's for the better surfers. The crowds will be out because it’s the first proper day after the storm.

Saturday the 22nd is another great option, with 8ft and a light cross-offshore breeze in the morning. That’s clean and powerful, a much more manageable size than Friday. Definitely one of the best on offer for the average good surfer. The afternoon gets a bit scratchy.

The following week starts off okay. Sunday the 23rd fades a bit into the 6ft range. Monday the 24th, however, looks promising again. The wind goes glassy on Monday morning with 8ft of WSW swell, and a 14-second period. That’s a proper clean session, a real standout for that second week. But remember, it’s long-range, so treat it as promising rather than set in stone.

The long-range outlook for Tuesday the 25th shows another big, stormy pulse. It’s onshore and building to 12ft. That’s likely to be another messy day. So, to wrap it up: this week, Thursday the 13th and Friday the 14th are your best bets for clean, manageable surf. Next week, Monday the 24th morning is the one to keep an eye on for a glassy, powerful day. The big, wild days in between are for the experts only.

Rusty out.

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.
