The Lowdown

Right, folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

First up, the surf has been hammered by a massive swell event, so we’re looking at a bit of a gap before things calm down. The energy in the water is absolutely pumping, with readings hitting 4-digit and even 5-digit numbers, which is some serious, heavy-duty ocean. The water temperature is sitting at 64°, which is a bit colder than normal for this time of year, so you’ll want a good steamer.

Friday 17 July is a write-off – light rain and a 22 mph NNW wind creating cross-on conditions on a 5 ft WSW swell. It’s lumpy and ugly. That big pulse hits Saturday 18 July – a raw 13 ft WSW swell, with a 15-second period, but the wind is onshore at 9 mph. The combined energy is a massive 6929 (moderate wave energy), but it’s just too big for this spot. The finder says it’s too big for Trigg. It’s a no-go for paddle surfing; this is kite-surfing territory if you’ve got the balls.

Sunday 19 July is the first real standout. A clean 8 ft swell from the WSW with a 14-second period hitting Trigg Beach (Perth, WA) in the morning. The wind is a light, cross-offshore NNE breeze at 6 mph. The combined energy is still a solid 2689, and it’s clean and the conditions are described as excellent for experienced surfers. This is a good one, but it’s a big wave for the average punter. If you’re a confident intermediate or expert, get on it. The crowds are often here, so expect company.

Monday 20 July morning is glassy. A 5 ft WSW swell with a 13-second period, and the wind is a dead flat calm from the NE at 3 mph. The combined energy is 822 (moderate wave energy). This is a sneaky good session – clean, glassy, and manageable. The finder says “expect very good surf conditions.”

Tuesday 21 July morning is also clean, with a 5 ft SW swell and light cross-offshore SSE winds. Not a massive standout, but a solid, workable surf.

Wednesday 22 July morning is another cracker. A 5 ft SW swell with a 13-second period, and the wind is a clean offshore from the E at 6 mph. The combined energy is 905 (moderate wave energy). The waves will be clean and lined up. This is a top pick for the mid-week.

Thursday 23 July and Friday 24 July mornings are similar: clean, manageable swells around 4 ft to 5 ft with light winds. Friday morning is glassy with a 4 ft WSW swell. Good, reliable fun.

Saturday 25 July morning is glassy again, but the swell drops to 4 ft. It’s a mellow session.

Sunday 26 July morning brings a bigger swell back – 6 ft from the W with a 12-second period, and light cross-offshore NNE winds. It’s clean and punchy, with combined energy at 1556 (moderate wave energy). This is another good one for the weekend.

Monday 27 July is a write-off – strong winds and a big, messy 8 ft swell. Skip it.

Tuesday 28 July morning is glassy again, with a 6 ft SW swell and a 14-second period. A clean, powerful option.

Wednesday 29 July and Thursday 30 July are both poor – strong winds and messy conditions.

Friday 31 July and Saturday 1 August are a massive, bombastic swell event – 16 ft waves with insane energy (11,801 to 14,218). This is for experts only, and even then, the wind is cross-onshore and choppy. It’s too big for Trigg. Kite-surfers might be frothing.

So, the top two standouts are Sunday 19 July for the experienced crew and Wednesday 22 July for a clean, solid session. The long-range stuff (end of July into August) is massive and speculative, but also looks like a lot of wind and chop.

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.
