The Lowdown

Alright, let's break down Trez Hir over the next couple of weeks. To be honest, the first week is looking pretty bleak. The surf is tiny and the wind is all over the place. You’ll be battling a moderate cross-onshore breeze most days, making for choppy, lumpy conditions that just ain't worth paddling out for. Water temp here is 63°, just a touch cool for this time of year, nothing crazy. Wave energy is weak to moderate at best, hitting only 47 on the scale Sunday morning, which tells you just how little push there is.

Sunday the 23rd and Monday the 24th? Total loss. Tiny 1.0ft to 2ft swells with cross-onshore winds, you're better off on the beach. Tuesday the 25th sees a slight bump, with the swell rising to 2ft to 2ft from the WNW, and the wave energy climbs to 124, but the wind is still messy. It's not until late Wednesday the 27th that we get some size, with a 7ft SW swell on Thursday morning, but the wind is howling cross-shore at 30 km/h and there’s a risk of thunderstorms. Wave energy jumps up to 782, but with that onshore chop, it's not going to be any fun.

Now, here is the one window that stands out. Friday the 28th morning. We get a 10ft swell from the WSW with a 10-second period, and the wind is doing the right thing – a clean cross-offshore breeze at 35 km/h. Wave energy is a whopping 3992, so there is plenty of power in the water. This is proper groundswell, and for an intermediate to expert surfer, this is the highlight of the forecast. The sets will be solid, the waves will have some shape, but it’s big enough that beginners should give it a miss. The morning session is the call, as the afternoon wind backs off and the swell drops a touch to a still-chunky 7ft.

After that, Saturday the 29th holds onto a solid 8ft W-NW swell early, but the wind stays cross-offshore and clean. The wave energy is still strong at 839, so it will be a fun, slightly smaller follow-up day. Then we drop off into smaller, less appealing surf for the rest of the weekend and into September. Tuesday the 1st of September has a tiny window of clean 3ft waves on the Monday afternoon with a moderate offshore breeze, but it’s small and ordinary. Thursday the 3rd of September morning even goes glassy with a tiny 0.3ft groundswell of 16 seconds, but there’s just no wave to surf.

So, here’s the takeaway: the best of the bunch is hands-down Friday the 28th of August, with that big, clean WSW swell. Thursday the 27th is too windy and stormy, and after that, it fades fast. There's about a three to four day run of no real surf recommendations through the start of September. If you want solid waves in clean conditions, your window is narrow – that Friday morning is the one.

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.
