The Lowdown

G’day, I’m Rusty, and this is your local surf outlook for Trez Hir. Let’s be straight up – the next 16 days are a real mixed bag, with a lot of flat, small, or messy conditions to wade through before we get anything worth paddling out for. There’s a long, lean gap from the start until we finally see a window of real potential.

The first recommendation doesn’t appear until Wednesday, August 12th, and even then, it’s nothing to write home about. The water temp is sitting right around average for this time of year at 64°, with no real anomaly to speak of.

Wednesday morning, August 12th, sees a bit of life with a 3ft swell from the west and a 10-second period, but it’s a cross-onshore breeze from the south, only 6 mph, so it’s light but onshore. The combined wave energy is moderate at 123, but the surf is ordinary. By the afternoon, the wind shifts to a light offshore from the northwest at 9 mph, cleaning things up, though the swell stays small at 3ft and energy drops to 109. It’s surfable, but it’s a struggle to get excited.

Thursday morning, August 13th, is where things start to look interesting. Trez Hir gets a clean 4ft swell from the west, with a period of 11 seconds – that’s a nice groundswell with good shape and energy. The wind is offshore from the north-northwest at 9 mph, making for clean, peeling conditions. The combined energy hits a solid 284 (moderate to strong). This is the first true standout. The morning session on Thursday is the best on offer in the first week, with good, clean waves. The afternoon gets messy with a stronger offshore wind up to 16 mph, which will blow it out a bit.

We then hit a dry spell from Friday, August 14th, right through to Monday, August 17th, with small, weak swells and mostly cross-off winds. The energy drops right off, with most readings under 170. The surf is poor, and it’s a quiet few days.

Then, on Monday afternoon, August 17th, the swell starts to build again. We get a 5ft swell from the west-northwest, with a period of 9 seconds and a fresh offshore wind from the west-northwest at 22 mph. The combined energy jumps to 383 (strong). Conditions are marginal, but there’s power.

Tuesday, August 18th, is the real standout for the whole outlook. The morning is clean with a 5ft swell from the west-northwest, 8-second period, and cross-off winds. The energy is 302 (strong). But the afternoon is where it’s at: a clean 7ft swell from the west-northwest, 8-second period, with a moderate offshore wind from the west-northwest at 12 mph. The combined energy is a powerful 549 (strong). This is proper, punchy surf. It’s a solid wave, but at 7ft, it’s heading into expert territory – not for beginners. The wind is offshore, so the waves will be clean and lined up. Trez Hir is a fairly exposed spot, and the swell direction from the west-northwest is a good match for the optimum south-southwest direction? It’s not perfect, but the energy and wind make it work.

Wednesday morning, August 19th, drops back to a tiny 0.3ft swell from the southwest with a very long period of 16 seconds. That’s a groundswell, but it’s too small to do anything. By the afternoon, we get a 5ft swell from the west-northwest, 9-second period, with a moderate offshore wind from the north-northwest at 12 mph. The energy is 302 (strong). That’s a good, clean afternoon session, but it’s not as big or powerful as Tuesday.

From Thursday, August 20th, through to Sunday, August 23rd, the forecast goes quiet again. The swell drops to 0.3ft to 2ft, with weak energy and poor conditions. There’s a small, promising 5ft swell on Saturday, August 22nd, from the west-northwest with a 9-second period and a gentle cross-off breeze, giving 371 energy (strong), but it’s only marginal and the wind picks up in the afternoon. By Sunday, August 23rd, it’s back to tiny, weak swells under 0.3ft.

So, the pick of the bunch is definitely Tuesday afternoon, August 18th, with that 7ft, clean, offshore swell from the west-northwest. It’s got power, it’s clean, and it’s solid. The runner-up is Thursday morning, August 13th, with the 4ft, 11-second groundswell and clean offshore wind. For the rest of the time, you’re mostly looking at small, weak, or windy conditions. Trez Hir rarely breaks, and this outlook shows exactly why – it takes a specific combination of size, direction, and wind to get it firing.

This is Rusty, signing off.

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. Our Trez Hir 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 (Trez Hir) 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 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.
