The Lowdown

G’day, Rusty here. We’ve got a 16-day window for Trez Hir, and it’s a bit of a slow burner. The first solid recommendation doesn’t kick in until Wednesday afternoon, the 16th, so we’ve got a quiet start. After that, there’s decent pulse building through the first week, and then things get properly heavy late in the second week – but that’s a long way off, so keep the lid on expectations for now.

The water is sitting at 63°, which is just about normal for this time of year – nothing unusual there.

Wednesday afternoon, the 16th, is where we start to see real life. Trez Hir picks up a clean 8ft swell from the WNW, with a solid 11-second period behind it. Offshore wind from the NW (25 mph) is keeping things glassy and lined up. The combined energy is strong at 1406, so there’s proper grunt in the water. This is for experienced surfers only – too much juice for beginners. This looks like the best on offer in the first week, hands down.

Thursday the 17th stays punchy but gets a bit messy with cross-off winds and building cloud. Swell holds 7ft to 6ft from the WNW, but the quality drops off – still surfable but nothing special.

Friday the 18th sees that energy spike again. Morning and afternoon both have 8ft WNW swell, but the period jumps to 14 seconds – that’s long-period groundswell. Combined energy peaks at 2742 in the morning. However, the wind is cross-off, and the setup is a beach break rocky point? Trez Hir is rarely breaks, so it’s inconsistent by nature. Still, if it’s on, this is for confident surfers only. That long period means the sets will stand up proper, but can fold over too quickly on a beach – so you need to pick your peak.

Saturday the 19th drops back a notch – 7ft to 7ft from the WNW, cross-off winds, moderate energy. Decent enough but a step down.

Sunday the 20th brings a pick-me-up: 5ft from the WNW, with light offshore breezes in the afternoon and gentle conditions. Combined energy around 526 – moderate, fun-sized waves. A nice window for intermediate surfers who want clean, manageable lines.

Monday the 21st fades – 5ft, dropping to 5ft, with cross and cross-off winds. Not worth a special trip.

Tuesday the 22nd morning is a write-off – onshore wind, poor quality. But Tuesday afternoon, watch out: a 5ft swell from the W comes in with a massive 16-second period, combined energy of 1650. That’s very long-period groundswell. The wind turns cross-off, so it’s clean. For a break like Trez Hir, which is rarely consistent, this could fire – but again, long-period swells at beach breaks are fickle. Still, the potential is there for the patient surfer.

Wednesday the 23rd through Friday the 25th is mostly choppy, onshore, and poor. Energy drops to as low as 137 by Friday morning – barely a ripple. Not much to get excited about.

Then we hit the second week and the long-range burner. Saturday the 26th afternoon: 8ft from the WNW, 14-second period, light offshore wind (6 mph), combined energy at 2092. That’s strong, clean groundswell for experienced surfers. Rated excellent. This is the one to keep an eye on from a distance.

Sunday the 27th afternoon: 8ft from the W, but period drops to 8 seconds – short-period wind swell, so less shape, less power. Combined energy 854. Cross-off wind, decent but not special.

Monday the 28th afternoon gets serious: 13ft from the WNW, 11-second period, offshore wind at 12 mph. Combined energy of 3338 – that’s very strong. This is experts-only territory. Clean faces, heavy juice. Only for the bold.

Tuesday the 29th morning keeps it solid – 12ft from the W, 11 seconds, light offshore, energy at 2454. Again, experienced crew only.

Wednesday the 30th goes onshore and messy – skip it.

So, the standout sessions for me are Wednesday afternoon the 16th for the first clean pulse, and that Saturday the 26th afternoon into Monday the 28th for the bigger, longer-period groundswell – but that’s a promise two weeks out, so don’t lock it in just yet.

Crowds at Trez Hir are listed as “sometimes,” so if you hit a good window, expect some company. And remember, this break rarely breaks, so when it does, you need to be ready.

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. 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.
