The Lowdown
Alright, let me break it down for you. The name's Rusty.
First up, I gotta be straight with you – the next week and a half is looking pretty grim at Trestraou. We're staring down the barrel of a long stretch of flat, messy, and unrideable waves. From Wednesday the 5th right through until the end of the weekend on the 10th, it's all poor surf conditions with tiny, weak swell. Swell heights are mostly under 3ft, periods are short, and the wind is all wrong – cross or onshore – making for a choppy, bumpy ocean. The combined wave energy confirms this, with readings mostly under 100 (weak energy), and even the best of them is a paltry 308. It's a full-on write-off, honestly. The water temp is sitting at 65°F, which is pretty normal for this time of year.
We finally get a glimmer of hope on Monday the 11th, but it's still no good. The pattern continues with small, poor surf through the middle of the week. The combined energy does climb into the low hundreds by Thursday the 13th, but the conditions are still cross-onshore, so it's all just a bit of a frustrating tease.
Now, hold on. The real standout is shaping up for the third week of August. Look at the 16th (Sunday) and the 18th (Tuesday). That's where the action finally turns on. On Sunday the 16th, we see a solid 6ft to 6ft swell from the WNW, with a combined energy of 322 to 362 (moderate wave energy). The wind is a clean, cross-offshore breeze on the morning of the 16th, which is a major positive. That'll be the best session of the whole outlook if you can get out.
Then Tuesday the 18th brings the biggest pulse of the forecast. We're talking a 7ft to 8ft swell from the W/WNW, with the combined energy absolutely spiking to 562 and 892 (strong wave energy). The morning of the 18th has clean, cross-offshore wind. Now, a word of caution here: that 8ft swell is getting into expert territory, and the period is 8-9 seconds, which is short period, so it might be a bit of a handful. But for those with the skill, that Tuesday morning is the best opportunity on offer. The 19th (Wednesday) also holds solid 6ft to 7ft swell with clean conditions, so it's a good run.
And just when you think it's all over, the 20th (Thursday) puts a cherry on top. The wind goes glassy in the morning, with a 4ft WNW swell. The combined energy (232) is moderate, but with glassy conditions, it's going to be a beautiful, clean day for a longboard or a funboard.
To sum it up: the first 10 days are a total bust. The real standout is the run from Sunday the 16th through to Thursday the 20th, with Tuesday the 18th and Thursday the 20th being the absolute best windows. The 18th for power, the 20th for perfect, clean conditions. Trestraou is a sheltered spot, so it doesn't get the full brunt of the swell, but when it aligns, it can be a gem. Crowds are a possibility there, especially on the good days, so get up early.
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.
