Alright, surfers, Rusty here. Let's take a look at what's cookin' for Trestraou.
Honestly, this 16-day window is a tough one. We've got a massive gap of almost two weeks with nothing but small, messy, or just plain poor conditions. The first real chance of a wave that remotely looks like something to ride doesn't show up until late in the game. It's a real test of patience.
From Monday the 13th right through to Saturday the 26th of July, it's a write-off. We're looking at tiny 0.3ft to 2ft slop, with cross-onshore winds the whole time. Even the few days where the wind goes cross or cross-off, the swell energy is weak, sitting between 8 and 34 (weak), and the periods are short. The water temp is about average for this time of year. There's just nothing to work with.
Things get a little more interesting toward the end, but it's still not perfect. On Sunday the 26th of July, the swell finally starts to show some life. The afternoon brings a cleaner 5ft swell from the W, with a light cross-shore breeze from the NW. The energy jumps up to 334 (moderate wave energy). While the period is still short at 8 seconds, it's a vast improvement over the tiny dribble we've been looking at.
Now, the standout, if you can call it that, is Monday the 27th of July. The morning shows a solid 8ft W swell at Trestraou. The energy is massive at 1021 (very strong wave energy), and with a period of 10 seconds, there's some proper power behind it. The wind is light, blowing onshore from the NNE, which will make for messy faces, but at least there's a wave. At 8ft, this is expert territory only. It won't be clean, but for someone who knows what they're doing, it might be the only game in town. Afternoon sees the swell drop to 8ft.
So, here's the deal: if you're desperate, Sunday the 26th is your best bet for a cleaner, smaller wave, but keep your expectations on the floor. For the brave and the skilled, Monday the 27th has the size and power, but don't expect any perfection. A blank run like this is pretty normal for the area when the wind and swell don't line up, so keep an eye on the charts.
Rusty, signing out.

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.
