The Lowdown
Alright folks, Rusty here. Let’s get into it.
First up, it’s Trez Hir. This spot is a bit of a wildcard – it’s an exposed break that gets a mix of swell, but it *rarely breaks* so when it does, you have to pay attention. The water is sitting at 63°, which is pretty much normal for this time of year, so no need to worry about any weird temperature shifts.
We’ve got a bit of a slow start. Tuesday afternoon throws up a solid 8ft swell from the WNW, but it’s packing a short 9-second period and the wind is howling offshore at 19 mph. The energy is there (1000), but it’s just too messy and the conditions are marginal. Not worth the paddle.
Wednesday cleans up a little. The morning brings a 3ft WSW swell with a gentle offshore breeze, but it’s really ordinary. The afternoon drops to 3ft and it’s still just average. Thursday is a write-off with onshore and cross-shore winds, barely any swell.
Friday morning is where things start to look up. We get a 5ft swell from the west, 10-second period, and the wind is cross-offshore. The energy is moderate (453) and the conditions are clean. This is a solid session if you can get out. The afternoon holds at 4ft with offshore winds, still surfable.
Saturday afternoon is the real standout for the first week. A 5ft WNW groundswell with a 13-second period is rolling in, crossed with a light offshore breeze. The combined energy jumps to 1019, and the conditions are *very* good. This is a proper wave – long period, clean, and the point should be running nicely. This is the best on offer for the first week.
Sunday morning maintains the quality with a 6ft WNW swell and a 12-second period. Clean again. The afternoon drops a bit, but it’s still good.
Monday is glassy but small (3ft), and Tuesday and Wednesday are mixed with increasing winds. The second half of the week gets blown out by strong northerlies, and the swell fades into small, poor stuff until the 22nd.
Now, look ahead to Wednesday the 23rd. This is a long-range look, so keep the salt in your eyes, but it’s promising. A 6ft WNW groundswell with a 17-second period – that’s a very long period groundswell – and the energy is massive (2041). The wind is cross-shore, so it’ll be a bit textured, but that kind of period at Trez Hir, which is a reef, should produce some serious, lined-up waves. The afternoon bumps up to 7ft with a 16-second period and even more energy (2236). This is the one to circle. It’s only for experienced surfers though – over 8ft at a reef with that much power is not for the faint-hearted.
This is your heads-up: the first week has a couple of good windows, but the real quality is that groundswell on the 23rd. Keep an eye on the wind, but it’s the standout.

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.
