The Lowdown

Alright, grab your wettie and let’s talk about what’s on the menu down at Trestraou. It’s a bit of a rough start, gotta be honest with you. The next few days are looking pretty scrappy. We’ve got some small, weak swell rolling in, but the wind is just sitting in the wrong spots, mostly cross-onshore or straight on. It’s the kind of surf that gets your hopes up when you look at the forecast, but then you get there and it’s just lumpy, close-outs and mush. A real bummer, because there’s some juice in the water, but it’s all over the place.

The first week is a write-off for a decent paddle. Small waves and messy conditions. We’re looking at waves around 3ft to 4ft, with weak energy readings around 105-176. The wind is all over the shop, but it’s not helping us. This is the sort of period where the best bet is to give the board a rest and maybe go for a swim. A lot of time with the surfline looking pretty average, but that’s the way it goes sometimes. There is a little window on Monday the 18th with a bit more size, about 4ft, and it's cross-off, which will clean it up, but the period is short and the energy is a bit meh, so it’s not worth getting too excited.

It’s a long, drawn-out patch of nothing. We finally start to see a bit of life around the 27th of August. The magic number is Thursday morning when that swell shows up with a bit more intent. The wind is forecast to go glassy, with a 4ft west swell at 8 seconds. It’s still a bit short-period, so it might be a bit fat, but that’s the first time it looks like you might get a couple of clean ones. That’s your window. It’s the standout of the whole stretch because it’s clean. The water temp is 67°, which is a touch warmer than normal for this time of year, so no need for the thick booties.

After that, she just cranks up quickly, but it’s not for the faint of heart. That same south-west pulse builds into a proper winter swell by the 28th. By Friday the 28th, we are talking about a real beast, with a 13ft swell and a 12-second period, and a combined energy reading of 3871. Come Friday afternoon, that jumps to a 15ft at 13 seconds with a massive 5927 energy reading. That’s a lot of water moving, pure power. But the wind is going to be a problem – it’s howling onshore, so it’s going to be a nasty, lumpy mess. That is not a paddle; it’s a survival mission. There’s huge potential if the wind switches, but as it stands, this looks way more like a kite-surf kind of day than a paddle-surf day. The same goes for Saturday the 29th, with a 13ft swell. This is big, raw power, but the cross-onshore winds will just make it ugly.

So, the takeaway is this: don’t hold your breath for the next week. It’s flat, small, and messy. Then, just as it seems like it’s never going to happen, we get a few clean waves on the 27th. That’s the one to make a plan for. After that, the ocean turns into a monster, which is promising, but only for the brave and experienced. It’s a tale of two forecasts, that’s for sure.

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.
