The Lowdown
Right then, let’s have a look at what Trez Hir’s got cooking for us. The water’s sitting at a pretty standard 63°, nothin’ to write home about, just your average for this time of year. The next couple of days are a write-off, mate. Thursday’s a complete bust with poor conditions and a weak cross-shore wind that’s just messin' things up.
Friday morning though, that’s where it starts to get interesting. The wind swings around to a clean cross-offshore from the NNW at just 3 mph, and the swell fills in at a solid 5 ft from the west. It’s got a 10-second period, which is decent, and the combined energy is right up there at 400 (moderate). This is a proper session. The waves are gonna be clean and lined up. That afternoon stays clean too with an offshore breeze, though the swell eases off a bit.
Saturday afternoon is another clean window, with 4 ft from the WNW (420 energy) and a cross-offshore breeze. Solid, surfable waves. But the real standout for the first week is Sunday the 13th. The morning delivers 6 ft from the WNW, with an 11-second period and a whopping 740 combined energy. Wind is cross-offshore and light. That’s the pick of the early run – powerful, clean, and well-shaped. It’s a bit much for beginners, but intermediates will have a ball.
Monday and Tuesday drop right off, not worth paddling out for. Then Wednesday the 16th is a big one, but it comes with a warning. The swell jumps to 8 ft and 8 ft from the WNW, with energy readings over 1000. That’s serious grunt. However, the wind is a fresh cross-offshore, and the conditions are described as marginal. That size and energy, with that wind, is gonna be a handful. Only for the experts.
Another standout pops up nearly two weeks away, on Thursday the 24th of September. The afternoon session has an 8 ft westward swell with a 9-second period and a massive 1628 combined energy. The wind goes glassy, light from the SW. That’s a proper, powerful, clean swell, and it’s scoring the highest rating in the whole run. A big, clean, powerful day for the experienced crew.
Friday the 25th morning pushes even bigger at 12 ft from the WNW with a 14-second period – that’s a long-period groundswell – and an energy reading of 3992. The wind is cross-onshore though, so it’ll be a bit choppy. But then, Friday afternoon... it goes glassy. 8 ft from the WNW, a 13-second period, and a huge 2349 energy. The description says “excellent surf conditions for experienced surfers.” That’s your absolute best bet for the whole 16-day window, but it’s far out, so keep an eye on it.
For the rest, there are plenty of ordinary days and flat spells in between. Trez Hir is a fairly exposed spot that doesn’t break all that often, so when it does turn on, you’ve gotta be ready.
Stay safe, catch you in the water.

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.
