The Lowdown
Alright folks, Rusty here, with a look at what’s on the cards for Trez Hir. Gotta be honest, this place is a bit of a diva – it rarely breaks, so when it does, you gotta be on it. The water’s sitting at a pretty normal 63° for this time of year, so nothing unusual there.
The first real sniff of action comes on Tuesday the 15th. Morning’s a write-off with a weak 2ft swell and a NW wind onshore, but the afternoon shows some promise. The swell bumps up to 6ft from the WNW with a short 8-second period, and the wind swings offshore from the NW. The energy’s still modest, but it could be a fun little session if you’re not expecting much.
Wednesday the 16th is where things start to get interesting. Morning sees a solid 8ft WNW swell with a 10-second period, and while the wind is cross-off, it’s a bit gusty. But the real standout is Wednesday afternoon. We’re looking at a powerful 8ft groundswell from the WNW with an 11-second period, and the energy is pumping. That, paired with offshore NNW wind, is going to produce some excellent, clean waves for experienced surfers.
Friday the 18th is the absolute highlight of the whole window. We’ve got a very long-period, 14-second groundswell from the same WNW direction, pushing 10ft. The wind is a light offshore from the WNW in the morning, making for glassy conditions. This is a serious, expert-level swell. Trez Hir doesn’t offer this kind of quality often, so if you can handle it, this is the day to clear your schedule. Given that this break rarely breaks, this is a proper event.
The weekend calms down a lot. Saturday the 19th has a manageable 6ft swell but cross-shore wind and a chop. Sunday the 20th looks clean with a glassy, calm morning on a 5ft NW swell. It’s a nice day for a longboard, but nothing compared to Friday.
Further out, there’s another solid window around the 23rd and 24th of September, with a long-period 14 to 15-second swell arriving. On the 25th, the afternoon gets a clean offshore breeze and a 5ft groundswell. It’s promising, but remember, these long-range calls are a bit less certain.
After the 25th, it fades away into tiny, messy surf, with a few clean but weak pulses on the 29th and 30th. Overall, we have about a week of potential action before a noticeable drop.
The pick of the whole forecast? No question: Friday the 18th of September. Big, clean, powerful groundswell – that’s your session.
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.
