The Lowdown
Alright folks, Rusty here with the outlook for Trez Hir.
Gonna be honest with you, the next two weeks are looking like a real mixed bag, and for the most part, it’s going to be a waiting game. There’s a long stretch of pretty ordinary conditions on the cards, so don't get your hopes up too early. We’ve got a pretty blank run from the start here.
Kicking off Monday the 24th, we’ve got almost nothing. A tiny 2ft swell from the SE with a weak 6-second period, and the energy is really low at just 30. It’s clean with a light offshore NW breeze, but that’s about all it has going for it. Honestly, it’s barely surfable.
Tuesday the 25th through to Thursday the 28th morning is a grind. The swell stays small, around 2ft to 3ft, with short periods and mostly cross or onshore winds. The only standout from the whole period so far is the afternoon of Friday the 28th. We see a jump in size to a solid 7ft from the west, with an 8-second period and a clean cross-offshore breeze from the west at 30 km/h (that's about 19 mph). The energy is up there at 573, which is moderate. It’s a lot of swell, over 5ft, so it's getting a bit much for the beginners. But for the more experienced crew, that Friday arvo could be the best of the first week.
Then we hit the weekend, and things get a bit wild. Saturday the 29th looks lumpy and rough, with strong cross-shore winds. After that, we get into a run of bigger but messy surf. Sunday the 30th afternoon sees a 8ft swell from the WSW with a fresh cross-offshore, and the energy is strong at 604. That’s heavy, at over 8ft it’s expert-only territory. That trend keeps holding on Monday the 31st, with an 8ft swell from the west and a 9-second period. The energy jumps way up to 1085. The wind is a clean cross-offshore again, so if you’re an expert looking for a challenge, that Monday might be your window. But it’s marginal, with question marks on the tide.
The first week of September gets smaller and messy again. We finally get a tiny window on the morning of Thursday the 3rd. A 4ft WNW swell, 8-second period, with a light cross-offshore breeze from the north. It’s only getting a 1 out of 10, so it’s surfable but nothing special. The afternoon gets a bit better with a 3ft swell and a clean offshore NW wind, but it’s small.
Looking further out into the second week, we see a glimmer of hope. On Saturday the 6th afternoon, there’s a 5ft WNW swell with a nice long 11-second period, giving the waves some real grunt. The energy is strong at 529, and the wind is a clean cross-offshore. That’s the best looking swell in a while, but it’s still only getting a marginal score.
And then the real kicker shows up on the horizon. Tuesday the 8th of September afternoon. A massive 12ft swell from the WNW, with a very long 15-second period. The energy is off the charts at 7544, that’s very strong. With that kind of period, Trez Hir being a fairly exposed beach setup might get a bit straight and unruly. But the wind is a gentle cross-shore, so it’s not totally blown out. This is a serious, expert-only swell. It’s a long way out, so don’t book your flights yet, but keep an eye on it because it’s the only real standout in the whole outlook.
For the time being, unless you’re an expert eyeing those big swells late in the first week or that monster on the 8th, it’s mostly a few small, clean windows on the 3rd and that promising Saturday the 6th. Don’t expect much consistency.
Rusty.

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.
