The Lowdown
Right, Rusty here. Let’s break down what’s happening at Trestraou. It’s looking bleak for a while, but there are a couple of spots in the second week worth keeping on your radar if you’ve got patience.
The water’s running a bit warm for the season, about 65°, so that’s a small comfort.
The first week is mostly a no-go. Monday the 14th starts with a clean 3ft from the west, light cross-off wind, but the overall call is poor surf. The energy is weak at 173. The next few days are just messy – cross-shore winds, lumpy chop, and even though the swell bumps up to 7ft by Wednesday the 16th, the wind is all wrong, making it a chop fest.
Thursday the 17th morning is clean with a 6ft west swell and a cross-off breeze, but still not great quality.
Now, here’s the first real highlight. Friday the 18th. The swell jumps to 7ft from the WNW with a very long 13-second period and massive energy of 1514. That’s a proper groundswell. It’s clean in the morning, but 7ft is big – that’s for experienced surfers only. The long period will bring nice shape but might want to close out if it’s too straight. Sheltered breaks handle it better though.
Saturday the 19th morning is also clean with a 5ft WNW swell, 11-second period, and decent energy of 614. A solid, manageable session.
Sunday the 20th morning is your smooth option. Offshore wind from the SW, light, with 5ft from the WNW and moderate energy of 369. Clean lines, easy paddling. Perfect.
From the 21st through the 26th, it’s all downhill. Onshore winds, small chop, and fading swell. There’s a weird long-period swell on the 24th with a 19-second period but only 1ft – that’s just a slow, gutless roller.
Then, the last real standout comes on Tuesday the 29th of September. A 5ft groundswell from the WNW with a very long 12-second period and strong energy of 634. The wind is nearly glassy – just a slight air from the NNW. This is the one for the patient crew. Clean, solid, and well over a week out, so keep it on your list.
Best on the board: Friday the 18th morning for the big, powerful groundswell if you’re advanced, Sunday the 20th morning for a clean, cruisy session, and Tuesday the 29th as the hopeful sleeper.

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.
