The Lowdown

Alright, folks, Rusty here again, and I’m looking at Trestraou over the next couple of weeks. The honest truth is, there’s not much happening at all.

We start the forecast period on Sunday, August 4th, but don’t get your hopes up. The first few days have just tiny waves, about 2 feet, with a weak, short period of around 8 seconds. The wind is crossing onshore, creating a choppy mess. The water temp is holding around 66°, which is a touch warmer than usual for this time of the year, but that’s about the only good thing.

The first real window where you might see something is Tuesday morning, August 6th. The swell lifts to about 3 feet from the west, and the surf energy comes up a notch (131 in the juice). The wind shifts to a cross-offshore, so the faces will be clean. The problem is the period is still short, around 8 seconds, so the waves will be a bit weak and crumbly for a break that’s normally sheltered. It’s not a classic, but if you’re stuck, it’s the first real chance.

The next couple of days are bumpy. On Wednesday, August 7th, the swell floats around 4 to 4 feet from the west, with a bit more energy (143), but the wind goes cross-shore, which creates a cross-chop. It’s not glassy, just messy.

Honestly, after Thursday, August 8th, which is still around 3 feet but choppy from a cross-on shore wind, things fall apart. From Friday, 9th August, all the way through to Sunday, 18th August, the swell drops to pathetic levels – between 0.3 and 2 feet. The energy numbers are laughable, rarely breaking 60 (like 21, 3, or 5). The wind is often onshore or cross-on, making it unrideable slop.

There is one tiny glimmer way out. On Monday, 19th August, the wind finally turns cross-offshore from the WSW, giving a clean surface, but the swell is a flat 0.3 feet with a 10-second period. Not a wave. On Tuesday, 20th August, you get a similar tiny, clean slate. The absolute best in this whole window is Sunday, 18th August, when the wind is offshore from the SW, and the water is clean, but the swell is a pitiful 0.7 feet. That’s strictly a longboard or foiling day.

So, bottom line: Trestraou is in a prolonged flat spell. The first week has a brief, small, clean window on the morning of August 6th, and the far end of the forecast offers a clean but microscopic wave around August 18th. For the rest, it’s a blank run. This area tends to go quiet like this, so don’t sweat it – forecasts change. But for now, it’s a waiting game.

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.
