The Lowdown
Right, let’s be straight with you. The next couple of weeks are looking pretty grim for a proper paddle. We’ve got a solid window of poor surf ahead, so don’t be holding your breath for any magic.
The first real chance of anything decent kicks off on Monday morning, the 8th. Before that, it’s a write-off. A bit of energy fills in Sunday afternoon, but it’s weak and messy.
So, Monday the 8th at Trestraou, we see a jump in size to 5ft from the W, but the real story is the light SSW offshore wind. That’s going to keep it clean. The energy picks up to a moderate 510, and with a 10-second period, it’s surfable but nothing special. That morning session is your best bet. The afternoon backs off to 5ft, and a cross-off wind, still clean, but the energy drops a touch.
After that, it’s a letdown. Tuesday through the rest of the week is a mess of onshore and cross-shore winds, with size dropping off and the quality going straight out the window. The energy stays low and the conditions are choppy.
There’s a tease on Saturday the 13th, with a bit more size around 5ft on Friday the 12th, but the fresh winds and cross-chop kill it. We’re back to small, weak surf.
Then, around the 15th, there’s a whisper of a longer period groundswell from the WNW. On Tuesday morning, the 15th, we see 3ft, but the period jumps to 14 seconds. It’s clean with a cross-off breeze, but it’s small. The energy is moderate at 321. For a spot like Trestraou, a longer period like this can be a bit tricky, as it might not wrap in as well.
The rest of the run is just small and weak. A couple of glassy mornings, but nothing with any push. The swell just fades away to under 2ft.
So, if you’re keen, Monday morning is your window. It’s not firing, but it’s the cleanest we’ll see. After that, save your energy. This looks like a stretch for the kite guys more than anything, with the onshore winds and lumps.
Keep the faith, the ocean always comes back around.
Stay salty,

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.

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.
