The Lowdown

G’day, Rusty here, and I’ve got a long look at the Trigg Beach stretch. This is a spot that’s fairly exposed to a WSW swell, and it’s a beach and point setup.

Right now, the water’s sitting at 64°, which is a bit colder than normal for this time of year—so you’ll want a decent wetsuit.

We’re looking at a solid run of clean surf starting from Monday morning. Sunday morning is a bit of a write-off: 8ft of WSW swell, but that cross-on wind and a big combined energy of 2728 makes it feel lumpy and marginal.

Monday, 20th July, is where it gets interesting. The morning is glassy with a light NNW breeze, 5ft of WSW swell, period around 13 seconds, and a combined energy of 822. That’s clean, glassy, and well-shaped—a real standout. The afternoon holds up OK with 5ft, but the wind turns cross-on.

Tuesday morning, 21st July, is another beauty. Clean offshore wind from the ENE, 5ft of SW swell with a 14-second period, and energy at 865. That’s clean, punchy, and the swell direction matches the optimum WSW. This is a top pick for the week.

Wednesday, 22nd July, keeps the run going. Both morning and afternoon are clean with offshore winds, 5ft of SW swell, and periods around 13 seconds. Energy is moderate at 757 and 1155. Consistent, clean, and fun.

Thursday, 23rd July, is also clean with offshore winds, 5ft of SW swell, 14-second period. Energy is 817 in the morning and 678 in the afternoon. Solid.

Friday, 24th July, the size drops to 3ft. The morning is clean with cross-off wind, but the afternoon turns glassy with a SE breeze. Energy is around 400, so it’s weak but glassy.

Saturday, 25th July, similar story: 4ft to 4ft of WSW swell, glassy conditions in the afternoon. Energy is low, around 436 to 499. A small clean day.

Sunday, 26th July, the swell drops further to 3ft in the morning, but the afternoon sees a 2ft SW swell with a long 16-second period, energy at 482. That’s tiny but clean.

Now, Monday, 27th July, things get bigger and messier. The morning has 5ft of WSW swell with a 15-second period, but it’s cross-shore and choppy, energy at 1569. The afternoon turns into 7ft with a fresh cross-onshore wind and lumpy conditions. Not great.

From Tuesday, 28th July, through to the end of the forecast, it’s a rough stretch. The swell gets bigger—up to 15ft on the 31st—but the wind is onshore or cross-onshore, often strong, and the water is blown out. There’s a gale on the 30th with 13ft to 15ft swell and energy readings over 10,000. That’s serious energy, but for paddle surfing, it’s a mess. If you’re into kite surfing, the setup on those days might be more interesting.

For the best of the best, I’d say Monday, 20th July morning, and Tuesday, 21st July morning, are your standouts. Clean, glassy, good energy, and the swell is solid. After that, it’s a slow decline into wind and chop.

Remember, forecasts can change, but for now, get out there early next week.

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.
