The Lowdown
Alright, folks, let’s get into it. Rusty here, and I’m lookin’ at the charts for the next couple of weeks. Honestly, we’ve got a bit of a slow start. The good news is there’s a little window of clean surf to aim for, but you’ll need to be patient.
First up, the only spot on the radar is Trez Hir. It’s a finicky one, to be honest – it rarely breaks, so we’re already up against it. The water temp is sitting at 63°, which is about average for this time of year, so nothing wild there.
The outlook kicks off with a real dud. From Sunday the 23rd right through to Wednesday the 27th of August, it’s basically a write-off. We’re talkin’ small, weak swell with a combined energy as low as 32 (weak) and messy cross-shore winds. Not worth paddling out for.
Things start to look a bit more interesting on Thursday the 27th. The morning brings a big pulse of swell - 7ft from the SW, which is a decent size. The combined energy jumps to 1292 (very strong), but the wind is howling at 19 mph from the SW and it’s cross-shore, creating a lumpy, choppy mess. That’s expert-only territory, and even then, it’s not clean. The afternoon drops a bit to 7ft, but still a messy cross-shore.
Now, the standout. If you’ve got a flexible schedule, point your board towards Friday morning, the 28th of August. The wind goes clean offshore from the NW at 9 mph, and we’ll have 4ft of WNW groundswell with a period of 10 seconds. The combined energy sits at 461 (moderate). That’s a solid, clean wave for a spot that doesn’t cooperate often. Conditions will be clean, and while there’s a chance of crowds, it’s worth it for a rare, clean Trez Hir session.
The following Saturday morning, the 29th of August, sees a bigger swell – 7ft from the W – but the wind is a cross-off at 19 mph. It’s clean, but that’s a lot of power, and with a period of only 8 seconds, it’ll be a bit walled up and more suited to stronger surfers. The energy is strong at 870.
After that, the second week fades out. Sunday the 30th and Monday the 31st have some size (7ft to 8ft) but the wind shifts onshore or cross-off, and the quality drops. Tuesday the 1st of September morning has a nice 5ft swell with a light offshore wind, but it’s a bit ordinary. The afternoon gets better with 4ft and a clean offshore breeze – that’s your second-best bet, but it’s a long way out.
After the 1st of September, the surf drops off hard. The swell goes tiny, under 3ft, and the energy is weak until the 6th of September, when we get a pulse of 5ft, but the wind is onshore again. The 7th of September is a total mess with 25 mph onshore winds.
So, your best bet is absolutely Friday morning, 28th of August at Trez Hir. Clean, offshore, and a rare day when that spot actually works. The 1st of September afternoon is a promising backup, but treat it as a long-range hope. For the rest of the time, it’s mostly flat or messy.
Rusty out.

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.
