The Lowdown
G'day, I'm Rusty. Let's have a look at what Trez Hir has in store for us over the next couple of weeks. It's a bit of a slow start, but there are some real gems hiding in there for those who are patient.
The first few days are a write-off, honestly. Sunday the 30th of August is a mess with a strong cross-shore wind and lumpy 5ft to 7ft swell – not one for a paddle. We've got a couple of days to wait until things start to clean up.
Monday the 31st of August is where it gets interesting. The morning brings a solid 8ft swell from the west with a 10-second period, and the wind has swung offshore from the WNW. The combined energy is a whopping 1447 (strong wave energy) – there's plenty of push. This is excellent surf for experienced surfers, but that size is too much for beginners. The afternoon holds at 8ft with the same clean offshore breeze, still very good. This is the first real standout of the period.
After that, we drop right back into ordinary conditions for a few days. Tuesday and Wednesday are small and weak, with energy dropping to 90 on Wednesday morning – that's barely a ripple.
Then, hold onto your boards, because Friday the 4th of September is the big one. The morning session is pumping with an 12ft swell from the WNW. That's a powerful groundswell with a long 14-second period, and the energy is off the charts at 4223 (very strong wave energy). The wind is offshore, so it'll be clean and lined up. This is strictly for experts at this size, but if you've got the skills, this is as good as it gets. The afternoon is still 10ft with a 13-second period and clean conditions, though the wind goes cross-off.
The weekend of the 5th and 6th of September is a mixed bag. Saturday morning has a slight onshore, but Saturday afternoon sees the wind go offshore again with a clean 5ft swell – a good option for a smaller board. Sunday is blown out.
We then go through a flat spell from the 7th to the 10th of September. The swell is small and the wind is messy or onshore, nothing worth chasing.
The second week offers another highlight. Friday the 11th of September sees a 8ft west swell with a long 12-second period and strong energy (1629). The wind is cross-off in the afternoon, so conditions are clean. This is a promising session, but given it's over a week away, treat it as a good prospect rather than a guarantee.
Saturday the 12th holds at 10ft, but the wind is stronger and cross-off, making it a bit more of a handful. We finish the period strong, though. Sunday the 13th of September has a clean 7ft swell with offshore winds in the morning, and the afternoon is even better – 6ft, 12-second period, moderate offshore wind, and the energy is 1350. This is excellent for experienced surfers, another real standout to end the run. Monday the 14th is still fun with a 4ft swell and clean offshore conditions.
So, to sum it up: if you can get out on Monday the 31st of August morning, or Friday the 4th of September morning, those are your two absolute best bets. The Sunday 13th of September afternoon is also a cracker. The rest is mostly for the die-hards or the kite surfers when the wind picks up.
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.
