The Lowdown

G’day, Rusty here. Looks like we’ve got a bit of a slow start before the ocean wakes up at Trigg Beach. The first real call is Thursday morning, 30 July, with a small 4 ft swell from the SW, but it’s a bit messy with cross-shore winds and only moderate energy. Not worth getting excited about yet.

Thursday afternoon stays similar, 4 ft from the WSW, cross-on breeze, and the energy bumps up a notch, but still just marginal. Friday morning, 31 July, things start to lift—6 ft from the WSW, 16-second period, cross-shore wind, and solid energy. Getting better, but the tide and conditions still hold it back. Friday afternoon blows out a bit, 7 ft but cross-on and choppy.

Saturday, 1 August, shows 8 ft swell from the SW and WSW, cross-shore winds, but the energy is strong. Still not clean enough to call it a standout. Sunday morning, 2 August, the wind swings ENE, goes cross-off, and we get 7 ft—cleaner, but still not the best.

Then Sunday afternoon, 2 August, we see the first real standout. The wind goes offshore from the ENE at 6 mph, swell sits at 7 ft from the WSW, period 13 seconds, and energy is solid. Conditions are clean. That’s your best call for the early window.

Monday, 3 August, drops back to 5 ft with light cross-shore wind, then Tuesday morning, 4 August, is a beauty. Glassy conditions, 8 ft from the WSW, 18-second period, massive energy. That’s a groundswell—long period, long gaps, perfect for Trigg’s point and reef setup. This is for experienced surfers; it’s solid. The morning is the pick.

Tuesday afternoon goes cross-on and choppy, so don’t hang around. Wednesday morning, 5 August, holds 8 ft with light cross-shore, still strong energy, but the wind is not as clean. Wednesday afternoon pushes 10 ft but onshore, messy.

Thursday 6 August, 8 ft, cross-shore, decent but not the standout. Friday 7 August and Saturday 8 August are a write-off—big swell (13 ft) but howling onshore winds, lumpy, messy. That’s for kite surfers, not paddle.

Sunday 9 August, a turnaround. Morning is clean, cross-off SSE wind, 10 ft from the WSW, 15-second period, energy through the roof. Excellent for experienced surfers. That’s another standout—big, clean, powerful. Sunday afternoon holds 10 ft but with a light cross-shore.

Monday 10 August, morning stays clean with cross-off NE wind, 8 ft, energy solid. The rest of the week fades a bit, with Tuesday 11 August dropping to 5 ft, and Wednesday 12 August is blown out by near gale winds. Thursday 13 August is messy, but Friday 14 August finishes strong: glassy conditions, 8 ft from the WSW, 17-second period, energy. That’s a clean, long-period swell for the experienced crew.

The water temp is 63°F, which is 3°F colder than average for this time of year—a bit nippy, so grab a thicker suit.

Overall, the standout sessions are Sunday afternoon 2 August, Tuesday morning 4 August, Sunday morning 9 August, and Friday morning 14 August. Those are the ones to circle.

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.
