Trez Hir Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s in store for Trez Hir over this 16-day stretch.

Right off the bat, it’s a bit of a slow start. We’ve got some small waves coming in, but nothing worth calling anyone about until the end of the first week. The opening shot is Monday afternoon, the 7th of September, with a 7ft swell from the west, period around 13 seconds – that’s a proper groundswell. The water’s sitting at 64 degrees, about average for this time of year. The wave energy is strong, hitting 1285, and with a cross-off wind, it’s going to be clean. That long period means it’ll be better shaped, but at a beach break like Trez Hir, it might want to stand up a bit too straight. Still, size and conditions are good.

The 8th looks messy. Tuesday morning brings an 8ft swell but with a nasty 37 mph near-gale cross-off. That’s blown-out, don’t bother. Tuesday afternoon sees the wind swing offshore from the NW at 19 mph and the swell drops to 8ft from the WNW with a 9-second period – that’s a bit too much wind and the period is short, making for a bumpy, less powerful wave. The energy is still high at 1072, but conditions are marginal.

Wednesday the 9th is small: 3ft in the morning and dropping further. Nothing special there. Thursday and Friday are even smaller with onshore or cross winds – poor quality all around.

Now here’s where it gets interesting. Saturday the 12th – we’ve got two sessions. The morning is tiny at 2ft, but the wind is glassy from the SSE at 3 mph. That’s rare. The swell period is a crazy 15 seconds, so that’s very long-period energy. However, at 2ft, it’s just not enough to surf. But Saturday afternoon? That’s a standout. A 5ft swell from the WNW at 14 seconds, combined energy 732, with light cross-off wind from the west at 6 mph. That’s clean, long-period, and punchy. Expert-level groundswell, but nice lines. Best session of the first week, hands down.

Sunday the 13th keeps the run going: 5ft to 6ft from the WNW, period 12-13 seconds, energy in the 740-800 range, light cross-off winds. Consistent, clean, and solid. Two great days in a row.

After that, Monday the 14th drops off fast into tiny 3ft junk. Then Tuesday the 15th picks up again: 5ft in the morning, 6ft in the afternoon from the WNW with an 11-second period, and moderate offshore winds from the NW at 12-16 mph. Energy is strong at 533-759. Clean, offshore, good shape. Wednesday the 16th follows with similar 5ft to 6ft WNW swells and offshore winds. That’s three more solid days mid-second week.

Then we hit a gap. From Thursday the 17th onward, the surf gets tiny or near flat – 2ft or less, or no swell at all. Winds become messy or cross-shore with lumpy chop. There’s nothing to ride during this gap of about 5 days. A marginal pulse on Sunday the 20th with 5ft from the WNW at 13 seconds and energy 673, but the conditions are questionable with a risk of thunderstorms and moderate cross-off wind. Not a recommendation.

The best of the whole outlook is Saturday afternoon the 12th and then the run from Sunday the 13th through to Wednesday the 16th. The 12th afternoon offers the best combo of swell size, long period, and glassy wind. The 13th through 16th are consistent, clean, and have moderate offshore winds. Trez Hir doesn’t break often, so when it comes together like this, it’s a treat. Crowds are possible, so get there early.

If the wind stays offshore and the swell holds, the 15th and 16th look like they’ll really deliver. That’s the kind of setup that reminds you why you surf.

Rusty.
