The Lowdown

Alright, let’s talk about Trez Hir. This spot “rarely breaks,” so when it does, you’ve got to pay attention. The forecast shows a bit of a slow start, but there’s a proper window of clean surf heading our way if you’re patient.

The water’s sitting at 63°F, which is pretty much what you’d expect for this time of year – nothing unusual there.

Thursday afternoon, the 3rd, is a write-off. Poor surf, cross-shore wind, and a weak, messy 5ft swell from the west at 8 seconds. Not worth paddling out.

Friday the 4th shows a big improvement. The morning is clean with a cross-offshore breeze and a 5ft west swell. The real standout is Friday afternoon: a solid 6ft groundswell from the west-northwest, clean and offshore with a northwest wind. The wave energy is strong (565), and the conditions are described as “gentle offshore and clean.” This is a good window to be in the water.

Saturday the 5th keeps the size up with a 7ft west-northwest swell in the morning, but the wind is a light cross-onshore, which puts a bit of a ripple on it. The afternoon is cleaner with a cross-offshore breeze, but you’re looking at a very long-period swell (12 seconds). That kind of energy can make a beach break like Trez Hir a bit too straight, so keep that in mind.

The real standout of the whole forecast is Monday the 7th. Monday morning delivers a 7ft west swell with a 13-second period, combined with a strong offshore wind from the northwest. Combined wave energy is a massive 1592, which is very strong. This is a powerful, clean, expert-level wave. The afternoon is almost as good, with 7ft and a 12-second period, still offshore. This is the best of the forecast.

Tuesday the 8th is still good, with a 6ft west-northwest swell in the afternoon and gentle offshore winds, but the energy drops a bit.

After that, the middle of the week gets smaller and wind-affected. From the 9th to the 10th, it’s small and choppy, with poor conditions. There’s a few days of small, clean surf from the 11th to the 13th, with 5ft to 6ft swells, but nothing that really stands out compared to that Monday.

The second week, from the 14th onwards, is mostly small, clean waves with 4ft to 5ft swell. Nothing to get too excited about, but if you’re desperate, the 15th afternoon has a clean 4ft wave. The 17th and 18th are small and ordinary, with building wind. The 18th morning has a fresh 19 mph offshore wind, but the swell is only 3ft.

So, the best bet is firmly Monday the 7th. That’s the one to circle.

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.
