Trestraou Surf Forecast and Surf Report

Alright, let’s get into it. This is Rusty, and I’m looking at what’s on offer for Trestraou over the next couple of weeks.

Honestly, the start of this outlook is pretty quiet. There’s nothing worthwhile for the first few days. It’s a slow start, with very small, weak swells and poor conditions. We’ve got a real gap here from Tuesday the 11th right through to the end of the next week. The waves are tiny, the energy is low – we’re talking combined swell energy values around 50 to 90, which is just dead. The wind is mostly cross-onshore or onshore, making for chop and generally messy surf. You’d be wasting your time paddling out.

The first glimmer of anything decent doesn’t show up until the morning of Wednesday the 19th of August. We’ve got a bit of a bump, with a 4.3ft west-northwest swell, but it’s a short period swell at 7 seconds. The real standout here is the wind – it’s glassy, absolutely flat calm. That is a rare and beautiful thing, so if you’re desperate for a paddle, that morning window is your best bet for clean, if not particularly powerful, waves. The combined energy is still weak though, at 149.

Moving into the second week, things get a lot more interesting, but it’s a bit of a mixed bag. The morning of Friday the 21st of August shows a cleaner setup with light cross-offshore winds and a 2.3ft west-northwest swell at 9 seconds. The combined energy jumps to 217, which is moderate and actually feels like some push in the water. The conditions note it as ‘surfable but very ordinary’, so it’s not a classic. Still, that’s the most potential we’ve seen so far.

Now, here’s where it gets real. For the advanced crew only. On Monday the 24th of August, a big, powerful westerly groundswell rolls in. We’re talking 8.2ft faces with a long 10 second period. The combined swell energy is massive – 1402 in the morning and 1249 in the afternoon. That is serious power. The wind is cross-offshore and the waves are described as clean. This is expert territory. The size alone (over 8ft) makes it too heavy for any beginner or intermediate. The long period also means it might be a bit straight-breaking at the beach, but if the banks are right, it’ll be a beast of a day for the experienced locals. This is the clear standout of the whole 16 days.

After that, it drops back down into a cleaner but more manageable zone. Through Tuesday the 25th and Wednesday the 26th, we have cross-offshore winds and dropping swell, from 5.9ft down to 3.3ft, with clean conditions. The energy drops from 445 down to 129. It’s good to finish on a clean note, but nothing compared to that Monday blast.

So, to sum it up: forget the first week. The glassy Wednesday morning on the 19th is a quiet and clean paddle. The real highlight, the one to circle on your calendar if you’re a charger, is Monday the 24th of August – big, powerful, clean, and for experts only. The end of the period cleans up for a nice session on the 25th and 26th.

Water temp is sitting at 66°F, which is a touch warmer than normal for this time of year. Nothing crazy, just a bit of extra tropical warmth in the water.
