The Lowdown

Right then, let’s have a look at Trestraou. To be honest, it’s a pretty bleak 16-day run for the most part. There are some swells that push through, especially around Sunday the 13th and again on Friday the 18th, but the wind is always working against us. The first real opportunity doesn’t show itself until the second week, so there’s a bit of a quiet spell to get through.

The water here is sitting at 65°, which is a touch warmer than normal for this time of year. Nice for a spring suit.

Let’s start with Sunday morning, September 13th. The swell builds to 5 ft out of the WNW with a 10-second period, giving a moderate wave energy (521). The wind is WSW at 12 mph and cross-offshore, which is the best part of this day – it’ll be clean. The rating’s only marginal, but this is the first decent look. The afternoon turns cross-shore and lumpy, so get out early.

Tuesday morning the 15th drops right back to 3 ft, so not worth a paddle.

Wednesday the 16th sees more size, 6 ft from the WNW, but a 16 mph cross-onshore wind chops it up. That’s more of a kite-surfing setup than a surfer’s wave.

We get a proper spike on Friday the 18th. The swell holds 5 ft from the WNW, but the period jumps to 13 seconds – that’s groundswell, proper energy (757). The problem is the wind is cross-shore all day, which kills the shape. Saturday morning the 19th brings a lighter SW at 9 mph, offshore wind, with 4 ft swell and a long 12-second period. That’s glassy and clean. This is your standout: Trestraou, Saturday morning the 19th. It’s not huge, but with clean conditions and a long-period groundswell, it’ll be the best shape on offer. The crowd situation is “sometimes”, so you might have company, but it’s not a zoo.

After that, the waves dwindle. By Sunday the 20th there’s 4 ft and cross-offshore wind, but it’s weaker. From Tuesday the 22nd right through to Saturday the 27th, we’re dropping below 3 ft most days, with the odd bump of short-period junk. The final day, Sunday the 27th, shows a bump to 7 ft from the WNW with a short 8-second period and clean cross-off wind. That’s a big wave, over 8 ft, so experts only, and the short period means it’ll be a wall of whitewater.

Overall, if you want clean waves, you’re looking at Saturday the 19th morning, and maybe a sneaky early Sunday the 13th. Everything else is compromised. It’s a patchy outlook, but at least there’s that one glassy morning to aim for.

Rusty.

Information about the Trestraou Surf forecast

The above surf forecast table for Trestraou provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu. Our Trestraou 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 (Trestraou) 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 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.
