The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Trez Hir over the next couple of weeks.

Right off the bat, things are a bit slow to start. The first real action worth paddling out for arrives on Sunday the 13th. We’ve got a moderate 5 ft swell rolling in from the WNW with a period around 11 seconds, and the wave energy is moderate at 634. It’s a bit of a mixed bag wind-wise, with a light cross-shore in the morning, but the afternoon turns clean with a cross-offshore breeze. This spot is a rare breaker, so it’s a treat when it lines up. The water temp is about average for mid-September, nothing wild.

Monday the 14th looks glassy in the morning – proper calm conditions with light winds from the south. The swell drops to a smaller 3 ft from the west, period 9 seconds, and the wave energy is low at 133. It’s not going to be pumping, but for a clean, cruisy session on a small board, it could be a nice little window. Crowds are sometimes an issue here, but it’s not the peak of the forecast.

The standout window, and I mean the real highlight, shapes up on Wednesday the 16th. The swell jumps to a solid 8 ft from the WNW with a period of 11 seconds. The combined swell energy is strong at 1390. That afternoon the wind goes offshore from the NW, giving us clean, lined-up waves. This is one for experienced surfers – at over 8 ft it’s pushing into expert territory. If you’ve got the skills, this is the session to circle on your calendar.

The following days see a mix of onshore and cross-offshore winds, with some decent 8 ft swell arriving on Friday the 18th. The energy is high at 2559 in the morning, but the winds are cross-offshore and the conditions are a little messy. Still, for a rare break like Trez Hir, any clean-ish window with size is worth a look.

The second week starts to tail off. There is a promising stretch on Monday the 21st and Tuesday the 22nd, with the swell holding around 4 to 6 ft, and Tuesday morning is glassy with light breezes from the SSE. The waves are clean and the energy is moderate at 371. A good chance for a relaxed paddle.

After that, the surf dries up. From Wednesday the 23rd onwards, we see a definite gap – several days with only small, weak swell and poor conditions. The last few days of the month are flat or close to it, with most of the energy reading in the single or double digits. Not much to report.

So, to sum it up: your top pick is Wednesday afternoon the 16th for the experienced crew, with solid 8 ft WNW groundswell and offshore wind. Keep Tuesday the 22nd morning in mind for a smaller, glassy session if you prefer it mellow.

Stay stoked,
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.
