The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for Trestraou.
It’s a quiet start, I gotta be straight with you. The first few days are pretty much a write-off. Sunday the 23rd and Monday the 24th have got nothing worth paddling out for – strong cross-onshore winds and tiny, weak swell. You’d be fighting a losing battle. We’ve got a bit of a wait on our hands.
Tuesday the 25th morning shows a flicker of life. The wind swings light offshore from the south at just 3 mph, and the water cleans right up. Swell is tiny, only 1 ft from the northwest with a period of 11 seconds – that’s a long period groundswell, so it’ll have some push but the size is just not there. The combined wave energy is weak (35). It’s a tease more than anything.
The real story starts to build towards the end of the week. Thursday the 27th morning sees offshore winds from the southwest, with the swell picking up to 3 ft from the west-southwest. By the afternoon, the swell hits 4 ft from the same direction, and the wind goes clean offshore at 12 mph. The combined energy jumps to a moderate 281. It’s surfable, but conditions are described as very ordinary – still, it’s the first time we get a real look.
Friday the 28th brings bigger numbers, but a big caveat. Morning sees a 5 ft swell from the west with a 10-second period, and strong offshore winds from the southwest at 25 mph. That sounds great, but the energy is strong at 356, and the wind is so strong it makes paddling out a real chore. It’s clean, but you’ll be working for it. The afternoon bumps up to 5 ft, but it’s cross-offshore and still blowing 25 mph.
Now, Saturday the 29th is the standout, but only for the experienced crew. The morning brings a solid 10 ft swell from the west with a 10-second period. Combined energy is a massive 1879 – that’s very strong wave energy. The wind is cross-offshore from the west-southwest at 19 mph, keeping things clean. But at this size, it’s expert territory only. Beginners need to stay on the sand. The afternoon stays big at 10 ft but the wind cranks up to 25 mph.
After that, we see the swell drop a bit. Sunday the 30th has a 6 ft swell in the morning from the west-northwest, dropping to 5 ft in the afternoon. Wind stays cross-offshore and fresh, keeping it clean, but the quality is still poor.
We then hit a lull. Monday the 31st through to Thursday the 3rd of September is tiny again – 1.0 ft to 3 ft at best. Not worth getting wet for.
Then, looking ahead, Friday the 4th of September shows a pulse returning, with a 6 ft swell from the west in the morning, building to 7 ft by the afternoon. The combined energy climbs to 685, which is strong. Winds are cross-offshore and fresh, keeping things clean. Saturday the 5th holds at 6 ft to 7 ft, and Sunday the 6th gets serious again with a 8 ft to 10 ft swell from the west-northwest. By Monday the 7th of September, we’re looking at a solid 12 ft groundswell from the west with a 10-second period, and the energy is off the charts at over 2900. That is a big, powerful ocean. Again, this is experts-only territory, and the wind will be strong offshore, making for some serious conditions.
Water temp is sitting at 66°F, which is a touch warmer than normal for this time of year – you can feel that difference in the water.
For the best bet overall, I’d point you towards Saturday the 29th of August morning for the sheer size and power, but you need to know what you’re doing. If you want something a bit more manageable, Thursday the 27th afternoon or Friday the 28th morning offer the best combo of clean conditions and surfable size for intermediate surfers. Crowds are sometimes a factor here, so keep that in mind.
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.

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.
