The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – the next couple of weeks are a tough watch for Trestraou. The water’s sitting at 66.6°, which is a touch warmer than normal for this time of year, so that’s something, but the actual surf quality is mostly poor. The good news is there’s a steady pulse of west swell, and the wind does go clean for some sessions, but the scores tell a story of ordinary conditions for the most part. The best stuff is hiding in the second week, but we’ve got to get through the flat and messy bits first.
We kick off Tuesday the 25th and Wednesday the 26th with tiny, weak surf. Swell is around 1.6 ft to 2.0 ft from the west-northwest and west, with combined energy barely hitting 60 (weak). The wind is cross-on or cross-off but light, so the waves are small and not worth paddling for. Thursday the 27th is more of the same – 1.6 ft to 2.6 ft west swell, 8-second period, energy only 32 to 113 (weak). Thursday morning has a clean offshore wind from the southwest, but the swell is just too small to get excited about.
Friday the 28th is when things start to pick up, but it’s still rough. Swell jumps to 5.6 ft in the morning and 6.6 ft in the afternoon, west swell with an 8-second period. Energy climbs to 386 then 496 (moderate), and the wind is offshore or clean cross-off. The problem is the quality – still marked as poor surf conditions. The waves are there, but they’re lumpy and lack shape. Saturday the 29th keeps the size going: 6.9 ft in the morning and 7.5 ft in the afternoon, west swell, 8-second period. Energy is strong at 573 and 703 (moderate-strong). Wind is a fresh cross-off from the west-southwest, so it’s clean, but again, the surf report calls it poor. It’s a bit of a tease – plenty of power but not the kind of wave you want to drive for.
Sunday the 30th shows a tiny glimmer. The morning has 5.6 ft west swell with a 9-second period, fresh offshore wind from the south-southwest, and energy at 461 (moderate). For the first time, the report calls it “marginal surf forecast or questionable tide conditions.”

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.
