The Lowdown
Alright folks, Rusty here. Let’s talk about Trez Hir. This little stretch of coast is your only play for the next couple of weeks, and it’s a real mixed bag. We’ve got some waves coming, but the consistency is a major issue and you’ll need to pick your windows carefully.
Right off the bat, the water temp is sitting at 63°, which is pretty much spot on average for this time of year, so no surprises there.
We kick things off on Saturday the 12th with small, weak surf. A 2.9ft swell from the west with a short 8-second period, and cross-shore winds making it a bit messy. The combined energy is only 213 (weak). Not worth getting wet for. The afternoon does clean up with a cross-offshore breeze and a slightly better 3.9ft WNW swell (414 energy), but it’s still only surfable, not special.
Sunday the 13th looks better. Morning has a clean 5.6ft swell from the WNW, period pushing 11 seconds, and those cross-offshore winds. The energy jumps to 665 (moderate). It’s a solid, fun size for an intermediate. The afternoon holds similar, just a touch smaller at 5.2ft. Monday the 14th is a write-off with poor conditions all day. Tuesday the 15th sees the swell drop right off in the morning (2.3ft), but here’s a standout for the week: Tuesday afternoon. The swell jumps to 5.2ft from the WNW, and we get proper *offshore* wind from the NNW. It’s clean, but the wind is a fresh 30 km/h (19 mph). That’s strong offshore, which will groom the waves but also makes paddling a real grunt. The energy is 490 (moderate). It’s a session for the fit and keen.
Wednesday the 16th brings the first big pulse. The morning has 6.6ft, but the period is a short 8 seconds, making it a bit crumbly. The real standout is Wednesday afternoon. We get a 6.9ft swell from the WNW with a 12-second period, combined with offshore winds. The energy skyrockets to 1910 (very strong). This is excellent, powerful surf for experienced surfers only. The size and power will be too much for beginners, and the long period groundswell could make it a bit straight at the beach, but on the right bank it’ll be world-class.
Thursday the 17th is a step down in size but still clean. Thursday afternoon has offshore winds and a clean 4.6ft swell. Then, Friday the 18th is another top contender. Both morning and afternoon offer excellent conditions. You’ve got 7.2ft swell in the morning and 6.9ft in the afternoon, both with a 13-second period and clean cross-offshore winds. The energy is 1672 and 1405 (very strong). Again, this is expert-level size and power, but the quality is fantastic.
After that, things get messy. The weekend of the 19th and 20th is poor, with bad winds and onshore chop. The only bright spot is Sunday the 20th afternoon – the swell drops to 3.3ft, but the period is a very long 16 seconds and the wind goes offshore from the NW. The energy is 894 (moderate). This will produce some beautiful, glassy, long-running lines on a point break if the direction lines up, but the breaks here are beach breaks, so the long period might make them a bit fat. A quality wave for a mellow, clean session.
The last week of the forecast window is mostly a bust. Monday the 21st has size but strong onshore winds. From Tuesday the 22nd through to the 27th, it’s a mix of flat spells, tiny swell, or poor wind. There’s a little window on Wednesday the 23rd afternoon with a 2.9ft WNW swell and clean wind (370 energy), and on Thursday the 24th morning a 3.9ft WNW swell with a 13-second period, but the onshore wind kills it. Honestly, the second week is for watching and waiting.
So, to wrap it up: the best on offer are Wednesday the 16th afternoon and Friday the 18th. Both are big, powerful, and clean, but strictly for experienced surfers on a bigger board. For a more cruisy session, Sunday the 20th afternoon could surprise you.
Stay stoked.

Information about the Trez Hir Surf forecast

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.
