The Lowdown
Alright folks, it’s Rusty here. Let's have a look at what’s on the cards for the next couple of weeks.
We’re starting off with a bang, but it’s a bit of a deceiving one. The first real opportunity is a big, powerful swell that’s not for the faint of heart.
Monday, August 31st is the kick-off, and it’s a heavy one. Trez Hir is absolutely pumping with a solid 10 ft swell thumping in from the west. The wave energy is right up there (1545), and it’s got a moderate, clean offshore wind from the WNW. The water temp is sitting at 64°, which is pretty much normal for this time of year. This is a serious session, but only for seasoned surfers – 10 ft is heavy, and the period is a tight 10 seconds, so it’ll be a powerful, fast-moving wall. The outside sets are going to be a mission to get through. The afternoon drops a touch to 8 ft, but still pumping with good energy.
Tuesday, September 1st sees the swell drop off fast. Wind shifts to a light cross-on from the SSW and the waves get messy. Not worth paddling out.
Wednesday, September 2nd through to Thursday, September 3rd is a write-off. Strong cross-shore winds and small, weak, choppy surf. The swell energy is moderate at best, but the wind is just ruining it.
Friday, September 4th we get a bit of a reprieve. The swell bumps up to 5 ft in the morning and 6 ft in the afternoon from the WNW, with a period of 10-11 seconds. The wind goes clean offshore or cross-off, making for much better shape. The wave energy is moderate-strong (567-645). This is a solid, surfable day for the capable intermediate.
Now, here’s the standout. Saturday, September 5th is the one to circle on the calendar. Morning session is looking prime. We’ve got a clean 7 ft swell from the WNW, but the period jumps to 13 seconds – that’s proper groundswell energy. The wind is a light cross-off from the NNE, keeping it glassy. The wave energy is huge (1555). This is excellent, powerful surf. It’s a bit big, so the experts will be in their element, but a strong intermediate could handle it. The afternoon drops to 6 ft with a 12-second period, still clean, but the energy is still strong.
Sunday, September 6th the swell plummets. Small, weak, and messy. The wind goes onshore, so it’s a flat, grovelly day.
Monday, September 7th through to Tuesday, September 8th is a mixed bag. There’s a weird, long-period (15 seconds) 2 ft swell on the Monday, but it’s barely there. The real action comes back on Tuesday afternoon: a clean 7 ft swell from the WNW with a 10-second period, a light offshore wind, and solid wave energy (718). That’s a good session for the Tuesday arvo.
Wednesday, September 9th starts with a fresh cross-shore and rain – messy. The afternoon cleans up with a gentle offshore, but the swell is down to 5 ft.
From Thursday, September 10th all the way through to Tuesday, September 15th, it’s pretty much flat. We’re talking a solid week of small, weak, choppy, or onshore junk. The energy is low, and the winds are mostly terrible. The last day, Tuesday, September 15th, has a glassy 3 ft wave from the west, but it’s just a very ordinary, small wave.
So, the best on offer is without a doubt Saturday, September 5th – that big, clean, long-period groundswell is the genuine highlight. The Tuesday afternoon session on the 8th is a solid runner-up.
Stay safe, check the tides, and I’ll see you in the water.
Rusty.

Information about the Trez Hir Surf forecast
The above surf forecast table for Trez Hir provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trez Hir can be found by selecting the local surf guide option on the grey menu.

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 Trez Hir 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.
