The Lowdown
Alright, Rusty here, and I’ve been staring at the charts for Trez Hir. Let’s see what we’ve got coming down the pipe.
Right off the bat, we’re looking at a bit of a mixed bag. The first few days are a write-off – Saturday the 29th and Sunday the 30th are plagued with strong winds and messy conditions. The water temp is about 64°, which is pretty normal for this time of year, so no surprises there. You’ll want to wait it out until Monday the 31st, because that’s when things start to get interesting.
Monday the 31st is where the real action kicks off. We’ve got clean conditions with a gentle offshore breeze from the northwest. The swell is a solid 8ft from the west with a 10-second period, packing a moderate punch (combined energy of 1316). The morning looks primo, with clean lines and the wind holding offshore. This is the standout of the first week – it’s got size, it’s got the right wind, and it’s just begging for a paddle-out. Tuesday the 1st of September drops right off, down to weak 4ft junk, so make the most of Monday.
We get a bit of a lull through the middle of the week. Wednesday and Thursday are small or onshore, nothing to write home about. But keep your eye on Friday the 4th of September. That morning is a beauty: a long-period 7ft groundswell from the west-northwest rolling in at 12 seconds. Combined energy is up to 1344, the wind is a gentle cross-offshore from the west, and it’s labelled excellent for experienced surfers. This swell will hold plenty of power but at that size, it’s for the crew who know what they’re doing. The afternoon on the 4th is also clean but a little smaller.
The second week goes a bit quiet again until a proper pulse shows up on the 11th of September. The afternoon of the 11th is a real standout for the long-range – 8ft from the west with a 13-second period and a combined energy of 2359, which is serious. The wind is light and cross-offshore from the north-northwest, and it’s glassy. That is a powerful, clean swell, but again, at 8ft it’s expert territory. The 12th and 13th of September keep the party going, with clean 6ft on the 13th afternoon and glassy conditions on the 13th morning. That whole final weekend from the 11th to the 13th is the real golden window for the second week, but remember it’s a long-range call so we’re keeping fingers crossed.
One thing to note – Trez Hir is a spot that rarely breaks, so when it fires like it’s going to on the 31st, the 4th, and the 11th-13th, you want to be on it. When it’s good, it’s worth the wait. The crowds are listed as “sometimes” busy, so expect some company on those peak days.
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. 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.
