The Lowdown

Alright, it’s your local man Rusty here, and I’ve been staring at the charts for our stretch. Honestly, it’s one of those outlooks where you have to be patient. There’s a big, quiet gap at the start, and the real action is a long way off. Let's wade through it.

First up, Wednesday morning the 6th of August, we get a little pulse at Trez Hir. Swell is a weak 1.0m from the WNW, but it’s only a 6-second period – that’s pure wind slop. Combined swell energy is a pretty weak (109). Wind is a light offshore from the NW, which is a positive, but with that period the waves will be too weak to bother with. For the next week and a half, it’s pretty grim. From the 6th right through to the afternoon of the 16th of August, we see waves that are knee-high at best, with poor conditions and low energy. There will be a few brief windows – like Tuesday the 11th of August where it goes glassy with a 0.6m swell, but that swell is still only 8 seconds, and the energy is only (56) – not worth paddling out for. Thursday the 13th is slightly bigger at 0.9m, but the conditions are just not packing any punch.

Then, things finally get interesting on Monday the 17th of August. On the morning of the 17th, we get a proper jump. The swell hits 1.8m from the west with a 7-second period. The combined energy shoots up to (381), and with the wind going cross-off from the WSW, it’ll be clean. The afternoon gets even bigger – 2.4m from the west. That’s entering the territory where only experienced surfers will want it, especially on a rare-breaking spot like Trez Hir. The energy is massive at (1097). The wind turns straight cross-shore from the SW, so the wave face won't be perfect, but there's meat in the water. It’s inconsistent and rarely breaks, so if it lines up, it could be a proper strike mission, but don't expect it to be easy.

The standout session for the whole 16 days looks to be Tuesday morning, the 18th of August. The swell holds at 2.4m from the WNW. The period is still short at 8 seconds, so it'll be a bit of a freight train – but the wind is solid offshore from the WNW at 30 km/h. That’s going to hold the wave face open and make it clean. The energy is still very strong at (821). For the experts who know Trez Hir, this is the one time in the whole run where the swell direction matches the optimum SSW exposure okay enough, and the wind does the rest. It’ll be too big for most, but if you’re skilled and looking for a slabby, punchy northwest swell, this is your window. The afternoon of the 18th is also decent with 2.3m and the same offshore wind, but the energy drops a little.

From Wednesday the 19th onward, it slowly fades. The 19th of August still offers clean, moderate waves around 1-1.4m with offshore NW winds, but the energy is dropping. By Friday the 21st of August, there’s a glimmer on the charts with a *clean, moderate-swell signal* and energy at (305), but the date is far out. Keep a loose eye on it.

Truth told, apart from that big, powerful window on the 18th, this is a quiet spell. Trez Hir rarely breaks as it is, and a blank run like this is not unusual here. But the 18th? That’s a one-day wonder if the forecast holds.

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.
