The Lowdown
Alright, Rusty here again, same outlook but in feet and degrees Fahrenheit.
Right now it’s flat and choppy – don’t bother. Wait until Monday September 7th when a solid 7ft west swell rolls in at 13 seconds. Offshore wind makes it glassy. That's strong energy (1367). That Monday morning is the one. Tuesday the 8th holds 5ft clean surf. Wednesday the 9th stays similar with clean waves. Thursday the 10th through the weekend is mostly messy cross-shore chop. Monday the 14th offers small 3ft to 4ft clean surf but nothing special. Wind goes wrong again until midweek. Wednesday 16th and Thursday 17th are cleaner but nothing standout. Sunday the 20th afternoon looks promising with 6ft WNW swell at 12 seconds and glassy offshore – a real good window. Monday the 21st afternoon has 4ft clean surf too. Trez Hir is a rarely-breaking spot, so when it's this good, get out there. Water temp around 63°, which is normal for this time of year.
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.
