The Lowdown
Alright, Rusty here, and I’ve been scanning the charts for Trestraou. Let’s be real, folks, it’s a grim start. For the first couple of weeks, the surf is virtually non-existent or just plain ugly. We’re looking at a long, dry spell from now until the tail end of the first week of September. The energy is weak, the wind is a mess, and the wave heights are barely a ripple. It’s a real bummer for the area, but these blank runs happen.
The first real flicker of hope comes on Saturday, September 5th. The morning is where it’s at. We’ve got a 6ft swell rolling in from the WNW, with a period of 10 seconds. That’s decent groundswell – it’ll have some shape and power, and the combined energy is a solid 689 (moderate). The wind is offshore from the SW, making for clean conditions. The water is a touch warmer than the norm for this time of year, sitting around 66°, so that’s a nice bonus. This is your standout window. The afternoon gets messy with the wind off the charts, but that morning session is the one.
After that, the swell drops back down and the wind goes onshore again, so you’ve got to make that Saturday morning window count. It’s a long wait, but when it finally shows, it’s worth paddling out for.
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.
