The Lowdown
Alright folks, Rusty here. Let’s break down this next stretch. The first week takes its time to get going, but there are a couple of moments worth setting the alarm for.
Monday the 17th is tiny – 0.2m from the WNW with an onshore breeze, not worth getting wet. Monday afternoon improves slightly to 0.8m with clean offshore wind, but the energy is low (106). Tuesday stays small and messy.
Wednesday the 19th morning bumps to 1.3m from the WNW, but the cross-off wind keeps it from being special. Thursday the 20th is the first real pulse: 2.2m of WNW swell, with combined energy jumping to 914 and then 1585. That’s a solid push, but the cross-off wind means it’s not perfect. This one is for experts only at that size.
Friday the 21st morning is the standout of the first week: 1.5m from the WNW, period around 10 seconds, energy of 436, and light offshore NNW wind at only 6 mph. Conditions will be clean and fun. Friday afternoon holds at 1.3m with moderate offshore wind – still very rideable.
Then the surf goes quiet. Saturday the 22nd through Tuesday the 26th is mostly flat or under 0.5m, with a gap of about four days where nothing is happening. Water temp is about normal for the time of year.
Wednesday the 27th morning brings 1.6m from the west with a short period and cross-off wind, but Wednesday afternoon is better: 1.8m from the WSW with clean offshore WNW wind at 12 mph (energy 336). Short period, but rideable.
Thursday the 28th is blown out. Saturday the 30th afternoon sees a big jump to 3.0m from the SW, short period (7 secs), with strong energy of 1291. That’s a lot of power, but the wind is cross-off and strong – expert only. Sunday and beyond look windy and messy.
The best of the bunch is Friday morning the 21st at Trez Hir – 1.5m, clean, light offshore wind. That’s your session. For the big-wave crew, Thursday the 20th has the size, and Saturday the 30th has the power, but both come with compromises.
Don’t force it when it’s flat. The ocean will come around.

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.
