The Lowdown
Alright, let's switch to feet and miles for the stateside crew.
Rusty here, and I gotta level with you – this forecast is a tough one. The water's a touch warmer than usual for this time of year, at about 66°, but the waves are the real story, and it's not a good one.
We start with a few days of nothing. The first real chance comes on Sunday, the 30th of August. The morning shows a 5ft swell from the west with a 9-second period, and the wind is offshore from the SW at 16 mph. That's clean, man. The combined wave energy is moderate at 371. It's described as "surfable but very ordinary," which is all we've got.
The rest of the week into early September is a mess. Monday the 31st of August sees a 8ft west swell, but the wind is cross-shore and the conditions are poor. That's a lot of water moving around with no shape. The wind stays strong and cross or cross-off for days, and the scores are all zero.
The next glimmer shows up on Saturday, the 5th of September. The wind goes glassy from the NNE at just 3 mph, with a 4ft WNW swell and a 10-second period. The energy is moderate at 307. It's clean, but it's a long way out and the conditions are listed as "unknown," so it's a gamble.
After that, it's back to small, weak, and mostly cross-shore or onshore winds. The swell drops below 3ft, the period gets short, and the energy plummets. By the 13th of September, there's a long-period swell of 14 seconds, but it's only 2ft. That's a tease.
If you're looking for a standout, it's the Sunday the 30th of August morning at Trestraou. Clean offshore wind, a 5ft swell, and moderate energy. It's your best bet by a long shot. The rest of the forecast is a paddling workout, not a surfing session.
Rusty.

A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu.

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 Trestraou 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.
