The Lowdown
Alright, Rusty here, let’s talk about what’s in store for Trez Hir over the next couple of weeks.
Right off the bat, it’s a tough start. There’s nothing worth paddling out for during the first few days through to the end of August. The swell is small, the wind is mostly cross or cross-on, and the reports just say poor conditions. You’re looking at a full six days with nothing on offer.
Things finally start to show a pulse on Friday afternoon the 28th. A 5ft WSW swell rolls in with a moderate offshore wind out of the NW, cleaning things right up. The combined energy is moderate, and the 9-second period isn't anything special, but it’ll be the first real chance to get wet after a long wait. The break here is a rare one, Trez Hir, and it’s not often it lines up, so when it does, it pays to keep an eye on it. Crowds are possible, but with the difficulty being intermediate, you won’t see too many beginners out there.
The standout of the whole window is Monday the 31st of August. The morning session is the pick, with an 8ft WNW groundswell running on a 10-second period and a moderate offshore wind from the NW, making for very good surf. The combined energy reading is strong. That’s proper swell, so it’s going to be a day for the experienced crew, maybe too much for beginners. The water temperature is pretty average for the time of year at 64°, nothing unusual there.
After that, the first week of September is a mixed bag. The swell hangs around but it gets cross-chop messy with strong SW winds pushing things around. Tuesday the 1st sees a 10ft W swell but winds are gusty and onshore, so the quality drops right off. The trusty NW offshore pops up again on Thursday the 3rd of September afternoon, with a 5ft W swell and clean conditions, worth a look if you’re itching for a late-day session.
Into the second week, there’s another promising date on the 8th of September, Tuesday morning. A 10ft WSW swell gets a 15-second period, and the combined energy is very strong. The wind is cross-shore and a bit lumpy, so it won’t be clean, but there’s raw power there for the strong paddlers. Long period like that usually makes for better shapes at a spot like Trez Hir, which is more of a reef or point setup, keeping the waves from breaking too straight. The very best looking window arrives on Wednesday the 9th of September afternoon with an 8ft WNW swell, light offshore WSW wind, and the data says excellent conditions for experienced surfers. That’s a long-range one, so keep your fingers crossed.
So, if you’re picking your battles, Monday the 31st of August morning is the clear winner, with Wednesday the 9th of September afternoon as the promising but less certain long-range option.

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.
