The Lowdown
Alright folks, Rusty here. Let's get into it. We've got a solid 16-day window ahead, but it's a real mixed bag at Trez-Hir. The first few days are pretty rough, with onshore winds and messy conditions, so you'll want to be patient. The standout window is from Monday the 31st of August through to the first weekend of September, with the best of the best falling on that Monday and Tuesday.
Water temp is sitting right around average for this time of year at 64°, so no surprises there.
Right, let's start with the grim stuff. The weekend kicks off with a decent sized but messy swell. Saturday the 29th and Sunday the 30th have strong cross-off and cross winds, with waist to chest high swell but it's all over the place. The energy is moderate (868 on Saturday morning, 1566 Saturday afternoon, but it's not clean. Wait for the wind to swing.
Monday 31st August is the real gem. The morning sees a solid 8 ft west swell, a 10-second period, and a clean offshore northwesterly breeze. It's packing some serious energy (1316) and the conditions are looking excellent. The afternoon holds up too, with a 7 ft west swell and a lighter offshore wind. This is the day to ditch work or school – you'll be rewarded with clean, powerful waves.
Tuesday 1st September is still a good option, but not quite as good. The swell drops to 4 ft in the morning with a cross-on south wind, so it's not great. The afternoon is smaller and cross-shore. Still, if you're keen, there's a wave.
The middle of the week from Wednesday 2nd to Friday 4th is a bit of a write-off. The swell hangs around in the 3 ft to 6 ft range, but it's mostly cross-shore or weak, and the energy is moderate to low. The best of this period is Friday afternoon when the wind goes offshore again, swinging WNW, with a 5 ft swell and a 9-second period – good, but not a standout.
Saturday 5th September is another belter. The morning has a 6 ft groundswell from the WNW with a long 12-second period, packing a good punch of energy (796). The wind is light and cross-on, so it might be a bit soft, but the afternoon cleans right up with a light offshore northwesterly and a 5 ft swell. This is a solid second pick.
Sunday the 6th onwards the surf drops off and the wind turns onshore again. The second week is a bit of a dud, with tiny swell and weak energy. There's a small, long-period swell on Sunday the 13th of September, but it's only 2 ft to 2 ft – barely worth a paddle. The energy is low (191-220), but it's clean and offshore. Only for the hardcore with a longboard.
So, to sum it up: Monday 31st August is the clear winner. Big, clean, and powerful. Saturday 5th September is your backup. The rest of the 16 days is mostly a write-off, with a long gap of poor conditions from the 6th.
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.
