The Lowdown
G'day, folks, Rusty here. Let's have a look at what's on the table for Trez Hir over the next couple of weeks.
Right off the bat, we’ve got a bit of a flat spell to sit through. The first few days are a write-off with no decent surf to speak of – Thursday the 10th and Friday the 11th morning are just not worth paddling out for. The real action doesn't start to stir until later.
The first real sign of life shows up on Friday afternoon, the 11th. We’re looking at a clean 4ft swell rolling in from the west with a gentle offshore breeze. It’s not a monster, but the conditions are clean and it’s a way better start than the morning. The wave energy is moderate (258), so it’s a solid little session.
The standout period for the first week is shaping up on Saturday afternoon, the 12th, and all of Sunday the 13th. Saturday afternoon jumps up to 5ft from the west-northwest, and the period stretches to 13 seconds – that’s proper groundswell energy. The wave energy is strong (788) and the wind is clean, cross-offshore. Then Sunday keeps the run going: 6ft in the morning, 5ft in the afternoon, both from the west-northwest with that 11-second period and offshore winds. The energy is strong (753 and 608). This is the best of the first week, no question. The water is about average for this time of year.
Now, the mid-week gets a bit messy. Monday the 14th and Tuesday the 15th have some small, ordinary waves, but the wind is a problem. There’s a notable pulse on the 16th (Wednesday) with 6ft to 7ft swell from the west-northwest, but it’s blowing a fresh 22 mph onshore. That’s more of a kite-surfing show than a good paddle session. The energy is strong (649-926), but the wind will ruin it for a surfer.
The real heavy hitter is Sunday the 20th of September. That’s the one to circle on the calendar. We’re talking a massive 12ft swell from the west-northwest with a ridiculously long 15-second period. The wave energy is enormous (9,913). This is deep, powerful groundswell that will push through. The wind is clean and cross-offshore in the afternoon, so it’s going to be a serious session for experienced surfers only. It’s a long-range standout, so keep an eye on it, but it has the potential to be the best day of the whole outlook.
The run continues into Monday the 21st with a still solid 7ft, 12-second swell that’s clean in the morning. It’s excellent for experienced surfers. After that, the swell fades back down, and the last few days of the month look poor with onshore winds and small, messy waves.
So, to wrap it up: the best windows are Sunday the 13th for a solid, clean weekend session, and then the big one on Sunday the 20th for the experienced crew. Don’t sleep on that.
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.
