The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cookin’ at Trez Hir.
First off, the water temp is sitting right around 64°F, which is pretty much normal for this time of year, so no worries there.
The next couple of days are a bit of a write-off, to be honest. Wednesday and Thursday have some size but the wind is messy and the swell is short-period, giving us weak energy (212) and then moderate (753-1611). It’s just not clean enough to get excited about.
Friday the 21st is where things start to look up. We’ve got a clean 5ft to 6ft swell from the WNW with offshore winds – gentle offshore in the morning, moderate offshore in the afternoon. The swell period is a short 9 seconds, so it won’t be the most powerful, but the clean conditions will make it fun. The combined energy is moderate (545 and 381). This is the best of the early window.
Then we hit a dry spell. From Saturday the 22nd through to Monday the 24th, it’s flat and blown out – tiny waves, fresh cross-shore winds, lumpy conditions. Nothing for a surfer to bother with.
Tuesday the 25th is still small, just 2ft to 2ft, with a bit more period (11 seconds) but the energy is weak (83-105). It’s not going to be pumping.
Now, keep your eyes on Wednesday the 26th. That’s a standout. The morning is glassy with a light SSW breeze, and the afternoon is dead calm – glassy as it gets. The swell is 5ft to 5ft from the WNW with a short 8-second period, but with that kind of glassy surface, it’ll be fun and clean. The combined energy is moderate (498 and 337). For a rarely breaking spot like Trez Hir, this is a real treat.
Thursday the 27th picks up in size to 6ft-8ft but the wind goes cross-offshore and it’s a bit lumpy, so it’s a marginal call.
The end of the month and start of September is a mixed bag. Friday the 28th through Sunday the 30th is mostly onshore, choppy, and poor. But then Monday the 31st of August brings a serious pulse: 12ft from the west with a period of 11 seconds, offshore winds, and massive energy (3036). That’s a big, powerful swell – definitely for experts only. The wind is fresh offshore, so it’ll be clean, but the sheer size will be intimidating.
The first week of September starts dropping off, but Thursday the 3rd of September afternoon could be a sneaky good one – 8ft from the WSW, 8 seconds, light cross-offshore wind, and very good conditions expected. That’s one to watch.
Overall, the best windows are Friday the 21st for a clean, fun session, and Wednesday the 26th for the glassy conditions. The big swell at the end of August is for the brave.
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.
