The Lowdown
Alright, lemme break it down for ya in feet and miles per hour. The next 16 days at Trestraou? Pretty much a washout, not a single session I’d recommend. The data gives every day a score of 1 or 0 out of 10 – “poor” or “marginal” across the board. This spot likes a good WNW swell and clean wind, but the timing’s all off.
Water temp is 65°F, a hair warmer than average – that’s nice, but it’s about all we got.
First up, Monday September 7th afternoon: cloudy, cross-shore at 9 mph, swell 6 ft from the west with a long 13-second period. Combined energy is 1060 – strong stuff – but the report says “marginal surf forecast or questionable tide conditions.” Not worth it. Tuesday 8th morning has offshore SW wind at 19 mph, 5 ft swell, but it’s heavy rain, and still only a 1. Afternoon turns sloppy: NW cross-shore 22 mph, 8 ft from the WNW – lumpy chop.
Wednesday 9th through the weekend is all junk. Thursday 10th morning is glassy but tiny – 2 ft, energy 96. Friday 11th morning is our best bet: light SW cross-off breeze, 4 ft from the west at 10 seconds, clean, and the note says “surfable waves but very ordinary.” That’s the top of the heap, and it’s still a 1 out of 10. After that, it’s downhill – tiny swell under 3 ft, weak energy, often cross-onshore wind.
There’s a long dry spell from about the 9th through the 22nd – days of flatness or poor conditions. The last few days (19th–22nd) show swells under 3 ft and energy under 100, with strong cross-off or onshore winds.
Bottom line: pack your board away for these two weeks. If you’re desperate, the Friday 11th morning window might give you a few grovelers, but don’t expect much.

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.
