The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you—this stretch for Trez Hir is a real mixed bag, and you’ll need to pick your moments. The surf’s not gonna be humming every day, but there are a couple of windows where it’ll be worth wetting a line.
We start off pretty grim. Friday the 28th is a write-off with tiny, weak 2ft swell and a messy cross-shore wind. Saturday the 29th gets a bit of size, but it’s a stormy mess—8ft to 11ft of chunky swell, but 28 mph cross winds and a strong cross-chop make it a washing machine. Not for the faint-hearted. Sunday the 30th is still lumpy with 5ft to 7ft of SW windswell and messy conditions, plus a risk of thunderstorms. Monday morning the 31st is marginal, but the real gem shows up Monday afternoon: the wind swings offshore from the NW at just 9 mph, the swell drops to a clean 7ft from the west with a 10-second period, and it’s got decent energy (928). That’s your first standout—clean, lined-up waves at Trez Hir, but the size means it's more for the experienced crew.
Tuesday the 1st of September holds some clean, gentle offshore vibes with 4ft to 4ft WNW swell, but the energy’s dropping. Wednesday and Thursday fade into smaller, cross-choppy slop. Friday the 4th is ‘surfable but ordinary.’ Then we hit a lull from Saturday the 5th onward—wave heights barely tickle 2ft to 3ft through to the 12th. A few glassy mornings (like Saturday the 5th and Monday the 7th) offer tiny, clean peelers, but you’ll be fighting for a ride. The long-range window around Saturday the 5th afternoon shows a 3ft WNW groundswell with 11-second period and clean offshore wind—good shape but small. That’s your second standout: a tidy little session if you’ve got a longboard and patience.
Overall, the best bet is Monday the 31st afternoon—solid 7ft west swell, clean offshore wind, and moderate energy. After that, the picks get smaller and more touch-and-go. It’s not a classic run, but keep an eye on those glassy windows.
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.

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.
