The Lowdown

Alright folks, Rusty here. Let's have a look at the only game in town for the next 16 days.

We're looking at Trez Hir, a spot that's exposed to the swell but rarely breaks, so we need everything to line up perfectly. Right now, the water is sitting at a pretty average 64° for the time of year, nothing unusual there.

The first week is a bit of a write-off, I'm not gonna lie. There's a gap of almost a week where we just don't have any decent surf on offer. We get a bit of a pulse on Wednesday the 5th with a 6ft W swell, but it's on a short 8-second period and the combined energy hits 408 (moderate). The wind is offshore though, so it'll be clean. But honestly, for a spot that rarely breaks, it's just not enough to get excited about. After that, it drops right off into tiny, knee-high dribble with almost no energy for days.

The real standout, the one you've been waiting for, is shaping up for Wednesday the 19th. That morning we're looking at a solid 7ft swell from the WNW. That's a fair bit of ocean, so it's heading into expert territory if it gets much bigger. The period is a reasonable 9 seconds, and the combined energy is a chunky 732 (strong). The wind is light and variable, essentially glassy. That's a rare combination for Trez Hir. For a break that's inconsistent, that's a window you don't want to miss. The afternoon before, on Tuesday the 18th, also looks promising with a 4ft WNW swell, a 10-second period, and offshore winds, making it a solid warm-up.

Other than that, there's a few other days with clean, offshore conditions but the swell is just too small to do anything with. The 17th sees a brief window of glassy conditions on a 4ft swell, but it's labelled as ordinary. The long 12-second period on the afternoon of the 17th might make it a bit tricky at a beach setup, but it's worth keeping an eye on.

So, to sum it up: the first week is a dud. The second week holds the key. Circle Wednesday the 19th on your calendar. That's the one.

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.
