The Lowdown
G'day, Rusty here, lookin' at the charts for Trez Hir. Right now, it's a bit of a sad story. The forecast is a long, flat spell with nothing to get excited about for over a week. We've got a solid gap from now until the 26th of July where the surf is just too small and weak to bother with.
For the first week, the swell is tiny, mostly around 0.7 ft to 2 ft, with weak energy. The wind is a mess, mostly cross or cross-off, and even when it goes glassy on the morning of Thursday the 23rd of July, there's just no wave to ride. It's a frustrating wait.
Things finally start to kick off on Sunday the 26th of July. The afternoon sees a little bump of 4 ft from the WNW, but the period is a short 7 seconds and the energy is still moderate. The wind is a clean cross-off, so it'll be tidy, but it's not exactly firing.
Then, from Monday the 27th of July, the energy starts building. We see a moderate 4 ft to 4 ft swell on Monday, then it jumps up to 5 ft on Tuesday morning, with the combined energy moving into the hundreds. By Tuesday afternoon, the 28th of July, it's a different story. The swell hits 6 ft from the WNW with a solid 12-second period, and the energy is a strong 1184. This is where it gets interesting, but it's still a bit of a gamble with the wind being cross-off.
The real standout is shaping up for Wednesday the 29th of July. The afternoon sees a solid 10 ft groundswell from the WNW, with the wind turning offshore. The energy is a powerful 1628. This is expert territory, as anything over 8 ft is for the experienced crew. The long period of 9 seconds means it will have some punch, but at a beach break like Trez Hir, it might be a bit raw and won't wall up as nicely as it would on a reef.
If you're an experienced surfer, the absolute best bet is Thursday the 30th of July. The morning is pure magic: a 15 ft WNW groundswell with a very long 12-second period, and the wind is a gentle offshore from the NW. The energy is a massive 5157. This is a big, powerful ocean. The conditions are clean, but it's strictly for experts. The afternoon backs off a touch to 13 ft, still offshore, and the energy is 3473. This is the window.
The end of the run drops off again. Friday the 31st of July and Saturday the 1st of August see the swell fading back to 4 ft to 7 ft, with the wind turning cross or cross-off, so it's back to ordinary conditions.
So, for the paddler, the pick is the 30th of July. It's a long way out, so keep an eye on it, but that's where the real power and clean conditions line up. The water temp is around 65°, which is pretty normal for this time of year.
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.

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.
