The Lowdown
G’day, Rusty here with the surf check.
Alright, mate, Trestraou is in a bit of a drought. The run of good surf is basically non-existent for a solid stretch. The first chance of anything you’d want to paddle out for doesn’t turn up until Thursday, August 20th. Before that, you’re looking at ten days of wind-blown slop and knee-high dribble. The waves are tiny, mostly under 3 feet, with short, weak periods and a lot of cross-onshore wind messing everything up. The wave energy is low, with readings under 100 for most of that time (54, 51, 47), meaning there’s just no power in the water. The water temp is about 60°F, so normal for the season, but it’s not going to make up for the flat spell.
That Thursday morning the 20th finally brings a change. The wind swings to a light offshore from the south-west, cleaning the surface right up. There’s some swell pushing in around 4 ft out of the WNW, with a period of about 9 seconds and energy hitting 201. It’s moderate power and it’s surfable, but it’s far from epic. The wind shifts onshore by the afternoon, chopping it up again. That morning window is your best bet, but it’s still a marginal session.
Friday the 21st morning offers another clean window with light offshore winds from the SE. But the swell drops back to about 3 ft from the WNW with a period of 9 secs and energy of 176. It’s clean and small, a good day for a longboard if you’re really keen, but nothing special. The rest of the 16-day window is more of the same: small, messy, and not worth getting excited about.
There are no true standouts. The break is sheltered and the swell direction lines up, but the size and consistency just aren't there. It’s a long flat spell for Trestraou.
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.
