The Lowdown

Alright, this is Rusty, and I’m looking straight at Trestraou for the next couple of weeks. Gotta be straight with you – it’s a slow start. We’ve got a long gap of flat, poor conditions before anything worth paddling out for pops up. The word here is patience.

The whole first week and a half is pretty much a write-off. From Thursday the 6th to Sunday the 16th of August, it’s all tiny, weak, and choppy. Swell heights are barely scraping 4 ft at best early on, but the wind is a mess – cross-on or onshore, making it bumpy and unappealing. The combined swell energy is mostly weak, in the double digits and low hundreds, meaning no real power behind it. The period is short too, under 8 seconds often, so it’s just mushy wind swell. You’d be better off doing something else.

There’s a glimmer on Monday the 17th of August. The morning shows a jump to 5 ft from the west with a period of 8 seconds, and the combined energy gets a moderate kick (279). The wind is a light cross-offshore, which is cleaner. It’s still described as "ordinary" conditions, so it’s a “maybe” for the keen and desperate, but at least the face will be a bit smoother.

The real standout, the one to circle on the calendar, is Thursday the 20th of August. The morning at Trestraou is looking like the best of the whole run. You’ve got a solid 7 ft swell from the west, period of 7 seconds, and the combined swell energy is strong (429). But the headline is the wind: a light cross-offshore from the southwest. That means clean, glassy faces. The report even says "expect good surf conditions." This is the one day where it all comes together. The 7 ft size is pushing it for beginners though – more suited to intermediate and above.

After that, Friday the 21st drops back off with messy cross-shore winds and smaller swell. So, to sum it up: don’t bother for the first ten days. The only real shot at a decent session is the morning of Thursday the 20th. Get on it if you can.

Stay salty,
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. 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.
