The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for Trez Hir over the next couple of weeks. It's a bit of a slow burner this time, so strap in.

Right now, we’re looking at a gap to start things off. There’s no real surf on offer until Monday the 14th, and even then, Monday’s a write-off with weak, messy 3ft swell from the west and a cross-onshore breeze. The water's sitting at 63° which is pretty much bang on average for the time of year, so no surprises there. You can leave your steamer at home.

Tuesday the 15th is where things start to get interesting. Tuesday afternoon is your first real standout. We’ve got a clean 5ft swell from the west-northwest with a moderate offshore breeze from the northwest. The combined energy is a solid (502) – that’s proper moderate juice, well worth a look. It’s a bit small for experts, but for intermediates and above, that’s a fun, clean afternoon.

The real highlight, and the best chance for a proper session, lands on Wednesday the 16th afternoon. That’s the pick of the whole window. You’re looking at 7ft of west-northwest swell with a moderate offshore wind. The energy is pumping at (1294), so we’re talking a lot of power here, but it’s well within the solid intermediate to expert range. The crowd profile says it can get a bit busy at times at Trez Hir, so get down early if you can.

After that, it trails off a bit. Friday the 18th sees a strong 10ft groundswell with a long 14-second period, but the wind is messy with a cross-offshore and the conditions are described as marginal. For a beach or reef setup, that sort of long-period energy can make things a bit fat and tricky to manage, so it’s one for the experienced crew only.

There’s another little blip on Sunday the 20th afternoon – 5ft of clean west-northwest swell and a nice gentle offshore wind. Very clean conditions there and the energy is (687). Not a classic, but a solid, fun surf. Not a standout.

After that, the second week goes flat and choppy. There’s a bit of a lull until the very end of the window. On Tuesday the 29th, we see a late burst of life. Tuesday morning brings a clean 6ft swell from the west-northwest with a 12-second period and light offshore winds from the north-northeast. The combined energy is (846) – that’s respectable, promising, but it's a long way out, so keep an eye on the forecasts but don’t book the day off work just yet.

So, the standout picks: Wednesday the 16th afternoon for the biggest, cleanest power session, and Tuesday the 15th afternoon as a solid warm-up if you want to get wet a day earlier.

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.
