The Lowdown
Alright folks, Rusty here. Let’s get into it.
Look, I’m not gonna sugarcoat it: the next week and a half at Trez Hir is a tough watch. We’ve got a long stretch of just nothing happening – from now until the end of August, the swell is tiny, the wind is messy, and the conditions are just ugly. It’s a real flat spell, and it’s not going to be worth paddling out for. There’s a good 10 to 11 days of pure frustration here.
But hold on, because things change. The first real glimmer of hope comes on Thursday the 3rd of September. The morning starts to show some promise with a building 8ft SW swell (period 7 seconds) and light offshore winds. That’s a solid start, but the real standout is the afternoon of that same day. We’re looking at a proper 8ft groundswell from the WSW, with a period of 9 seconds, and the wind is going fully offshore from the NW. That’s the kind of clean, glassy lineup we’ve been waiting for. The wave energy is going to be strong, with a reading of 1041, meaning there’s plenty of power behind it. This is a big-paddle day for intermediate and above – that 8ft is expert territory, but it’ll be the best wave we’ve seen in the whole run. The water temp is sitting at 63°F, which is about normal for this time of year.
The 4th of September still has some size, with 6ft to 5ft swell, but the wind goes onshore or cross-shore, so it won’t be as clean as the day before. Still, it’s a decent option if you missed the peak.
So, the call is simple: suffer through the flat spell, then be ready for Thursday afternoon on the 3rd of September. That’s your window.
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.
