The Lowdown
Alright, let’s cut to the chase. The next couple of weeks are looking pretty flat and weak for the most part. There’s a pulse of energy mid-week that will be the standout, but you gotta wade through some small, junky surf to get there. We are looking at a whole lot of nothing on offer for the start of the run, so don't be in a hurry.
The water here is sitting a touch warmer than normal for this time of year. You won't need a lot of rubber, but that extra warmth is a welcome thing when the surf is this quiet.
Saturday the 15th is a write-off. We've got a weak 4ft WNW swell with a short 8-second period, and the morning onshore is chopping it up. It’s a sheltered spot, but with that combo, it’s not doing anyone any favors. The energy is weak, coming in at 153, and it just doesn’t have any push.
Sunday the 16th drops even more, down to 3ft and running on a shorter 7-second period. The wind stays cross-on and it’s just poor. The swell energy has dropped to 90, so there’s not much to work with.
Monday the 17th, the size bottoms out. We’re down to 2ft and a 5-second period. The wind is cross-off in the morning, so it will be clean, but there's just nothing to ride. You’d be floating around waiting for a ripple that never comes.
Tuesday the 18th isn’t much better at 2ft with a short period. It’s clean in the morning again, but those conditions are wasted on flat surf.
Wednesday the 19th sees a slight bump back to 4ft but it’s short period and cross-on. It’s a bit more energy (124) but the quality is still poor. Not worth getting wet for.
Now, here’s where it gets interesting. Thursday the 20th. The swell jumps to 5ft in the morning and pushes to 6ft in the afternoon. The period stretches to 9 seconds and the energy is finally starting to read as moderate to strong, at 413 and 530. The wind is a clean cross-off, which will keep it looking decent. This is the best window of the run. It’s not huge, but it’s got some push and shape. This is your day if you’re keen.
Friday the 21st stays in the mix, with 6ft in the morning and 5ft in the afternoon. The period is still 9 seconds and the energy is strong (563 and 436). However, the wind is cross-shore and lumpy, so it’ll be less clean than Thursday. Still, it's the second-best option of this whole stretch.
After Friday, it’s a fast slide back to small. Saturday the 22nd drops to 3ft, and the energy is gone. It’s back to the flatness. The rest of the month is a tale of tiny surf with onshore winds, just a lot of nothing. There’s a brief pulse of 10ft on Monday the 24th with a strong 987 energy, but it’s coming from the NNE with fresh onshore winds and heavy rain. That is a messy, blown-out mess. And it’s over 5ft, so it’s not for beginners, but the conditions will be so poor it’s not for anyone keen on a clean wave. That setup looks more interesting for kite surfing than paddle surfing to be honest.
The long-range stuff into the end of the month is just small and junky. We’ve got a few days with zero hope, like the 27th and 28th, where the swell is under 2ft with almost no energy. It’s a pretty bleak stretch. The spot is inconsistent at the best of times, but this is a proper blank run.
So, the takeaway: Don't bother with the first few days. Save your energy for Thursday the 20th. That’s the standout. It’s a promising window but still a few days out, so keep an eye on it. Friday the 21st could still be fun if you can handle the lump. After that, it’s a long wait.

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.
