The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Trestraou. I’ll be straight with you – the next couple of weeks are looking like a bit of a write-off for quality waves around here.

We’ve got a long, flat spell with no proper surf recommendations at all through the whole 16-day window. The swell we do see never really gets its act together with the wind, and the combined wave energy is often weak. For instance, early on Monday the 3rd, there’s a tiny 2ft W swell with only 54 units of energy – just not enough push. The wind is cross-off in the morning, which would normally be a bonus, but with that small size and short 9-second period, it’s not doing us any favours.

Tuesday the 4th sees a slight bump in size, up to 3ft to 4ft from the W and WSW, with a bit more energy around 124 to 155, but still poor conditions overall. Wednesday the 5th pushes into the 5ft to 6ft range with energy climbing to 355 to 439 – that’s moderate energy now – but the wind swings onshore and lumpy, making a mess of things. For a sheltered spot like Trestraou, that’s a tough combo. The optimum swell direction here is WNW, and while we do get some WNW swell later on, the wind is mostly cross or onshore, ruining any chance of clean surf.

The whole first week and into the second is plagued by poor surf conditions. Thursday the 6th and Friday the 7th drop right back down to tiny 1ft to 4ft waves with energy falling to as low as 28. The wind is cross, cross-on, or even onshore, and the water temp anomaly isn’t noted, so it’s about average for the time of year. Crowds can be an issue here sometimes, but honestly, with this lack of quality, the lineup will be quiet.

We see a slight lift again around Saturday the 15th into Sunday the 16th, with swell building to 5ft from the WNW and energy hitting 300 – that’s moderate. But again, wind is onshore or cross-onshore, with chop. It’s a beach setup, and with that wind, it starts to look more interesting for kite surfing than paddle surfing.

From Monday the 17th through Tuesday the 18th, we’ve got 4ft to 5ft WNW swell with energy around 313 to 361, but the wind is onshore or cross-onshore, keeping things choppy and poor. Nothing to get excited about.

So, the bottom line: there are no standout sessions in this 16-day stretch. The blank run is pretty normal for this area when the wind and swell don’t line up. Forecasts can change, but as it stands, you’re better off leaving the board in the car for a while.

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.
