The Lowdown
G’day, this is Rusty. Let’s run through the next sixteen days for Trez Hir in feet and Fahrenheit. The water’s about 63°, which is normal for this time of year – no drama there.
The opening days are a bust. Thursday the 10th and Saturday the 12th are messy with cross-breezes and tiny waves around 3 to 3 feet. Not worth it. But Friday the 11th morning, the wind goes light offshore from the NW, and we get a clean 5-foot swell from the west at 10 seconds. Combined energy is moderate at 400. That’s your first decent shot.
Sunday the 13th is where it starts cooking. Morning has a clean 6-foot WNW swell with 11-second period, offshore NW wind at just 6 mph. Energy hits 834 – solid. The afternoon holds 5-foot with clean offshore breeze. That Sunday is a clear standout for the first week.
Now the second week gets serious. Sunday the 20th morning – dead calm, glassy, with an 12-foot WNW swell. Combined energy is massive at 1799. That’s expert-only territory. The biggest of the run comes Sunday afternoon with 13-foot, energy at 2504, but a cross-offshore wind nudges it. Monday the 21st morning delivers a 10-foot WNW swell with 13-second period – long groundswell – and energy at 4814. Very strong. Tuesday the 22nd morning is glassy again with 8-foot, energy 1570, excellent for experienced surfers. And Thursday the 24th morning – 8-foot with a 15-second period – that’s proper long-period groundswell, energy at 2617. The afternoon matches with 8-foot and clean offshore.
The top calls are Sunday the 13th for the first week, then Tuesday the 22nd morning and Thursday the 24th morning for the second week. This spot barely breaks, so when it does, you show up. Crowds are possible on those good days. Don’t sleep on it.
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.
