The Lowdown
Alright, Rusty here, let’s break down what’s happening at Trez Hir for the next couple weeks. It starts off real slow, but there’s a bangin’ day if you hold out.
The first week, from Wednesday July 29th into early August, is mostly flat and weak. Swell heights are in the 3ft to 2ft range, with short-period, weak windswell. The combined energy is mostly under 100 (44-111), so there’s no power behind it. Winds are cross-off or offshore pretty often, but with no real swell to work with, it’s just a waste. There’s a gap of over a week with nothing worth a paddle.
Then, Thursday August 6th afternoon shows a bump to 5ft from the SW, but the period is only 6 seconds – that’s junk. The real standout is Friday August 7th. Friday morning is glassy – zero wind – with a solid 7ft swell from the WSW, period around 8 seconds, and the energy reading is 521. That’s a proper surge. Friday afternoon gets even better: 6ft with a 20 km/h offshore NW breeze, energy up to 860. For a spot that rarely breaks, this is a huge opportunity. The swell direction from the WSW is a good fit for Trez Hir, and the offshore wind will keep it clean and lined up. The water temps are about normal for this time of year. This is the best window.
Saturday morning the 8th still has size – 5ft from the WNW – but light cross-shore wind and less energy at 482. Still worth a look. After that, the swell drops fast. By Sunday the 9th, it’s 4ft and dropping, and the rest of the second week goes back to small, weak waves under 3ft with light cross-off breezes.
To put it plain: over a week of nothing, then a killer day on Friday August 7th. That’s your chance. Trez Hir is inconsistent and rarely breaks, so when it fires, you get after it.
Keep an eye on it, forecasts can shift.
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.
