The Lowdown
Alright, Rusty here again. Let’s break this down in feet and knots.
The first few days at Trez Hir are a bust. Tuesday the 8th is a washout with rain, a 45 km/h cross-off wind, and a 8ft west swell that’s short-period and ugly. The energy is 814 (moderate), but the wind is just too strong. Water temp is a normal 63°F.
Wednesday the 9th drops hard. Swell is only 3ft and then 3ft. The winds are offshore, which is clean, but it’s tiny. Energy is 147 and 96. Weak. Thursday the 10th is even worse.
Friday the 11th morning gives us a decent window. A 5ft west swell with a 9-second period, and a clean cross-off wind from the NNW. Energy hits 392. The comment says “expect good surf conditions.” This is your best early option. Crowds are possible. The water is still normal.
Saturday the 12th morning is glassy, but the swell is only 1ft—that’s a 15-second period groundswell, beautiful but tiny. Energy is 163. Not worth it.
Saturday afternoon the 12th is the real gem. A 6ft WNW swell with a 13-second period. The energy jumps to 1120 (strong). The wind is a clean cross-off from the WNW. The forecast says “expect very good surf conditions.” This is the best wave of the whole forecast. The period is long, the swell direction is right, and the wind is perfect. It’s a bit big for beginners, but for anyone else, it’s a go.
Sunday the 13th holds on. A 6ft WNW swell, 12-second period, cross-off wind. Energy is 910 (moderate-strong). The morning is the better call. Tide might be a thing.
Monday the 14th and Tuesday the 15th are small. The 15th afternoon picks up to 4ft with a gentle offshore wind, which is clean, but not a standout. Energy is 398.
From Wednesday the 16th onward, it’s a long, poor stretch. The wind turns onshore or cross-shore, and the conditions are consistently poor. There’s a pulse on the 23rd with a 5ft WNW swell and a 13-second period, but the wind is a 30 km/h cross-onshore, making it lumpy. The energy is 599 (moderate), but it’s a no-go. The gap from the 16th to the end is a solid week of nothing.
So, the call is: Saturday afternoon, September 12th is the standout. Friday morning, September 11th, and Sunday morning, September 13th, are solid backups. The rest is a long flat spell.
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.
