The Lowdown
Hey, Rusty here. Let’s talk about Trez Hir. It’s a slow start, but there’s a solid run of swell coming in the second week that’s worth waiting for.
Right now, it’s flat and messy. From Friday the 21st of August all the way through to the end of the month, there’s nothing worth paddling out for. The wind is mostly cross-onshore trash, and the swell is either too small or too short period. The morning of the 21st had a clean 1.7m WNW swell with a light offshore breeze, but it’s a one-off and not enough to get stoked about.
The first real sign of life comes on Saturday the 29th of August. There’s a big 3.0m WSW swell in the morning, with a combined energy of 1562, but it’s marginal. The wind is cross-off, so it’s clean, but 3.0m is a big boy wave – only for the experts. The period is 9 seconds, so it’s a bit lumpy. That afternoon drops to 2.4m, still plenty of power.
The real standout is Thursday the 3rd of September, specifically the afternoon. We’ve got a 2.1m groundswell from the WNW, with a 10-second period, and a beautiful offshore wind from the NW at 20 km/h. The wave comment says "expect very good surf conditions." The energy is strong at 951. This is the pick of the forecast. Friday the 4th of September afternoon is also a beauty, with a 2.5m W swell, offshore NNW wind, and a "very good" call. Then Saturday the 5th of September afternoon keeps the goodness rolling with 2.4m WNW swell and gentle offshore wind. Those three afternoons are the ones to plan for.
Water temp is 17°, about 0.6° below average – totally normal for this time of year.
Trez Hir is a rare spot, so when it lights up, it’s special. Crowds can pop up sometimes, so get there early. The swell direction is a bit west of the ideal SSW, but the quality on those standout days will be well worth it.
Cheers, Rusty.

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.

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.
