The Lowdown

Alright folks, Rusty here. Let’s talk about what’s shaping up for Trestraou over the next couple of weeks. Gotta be straight with you – it’s a tough stretch. The pattern’s got some size, but the wind just won’t play nice for most of it.

Right out of the gate, from Monday the 14th through the end of the week on Friday the 18th, it’s a frustrating mix of bumpy and choppy conditions. Swell hangs around in the 3ft to 8ft range from the west-northwest, but we’re dealing with cross-shore and cross-onshore winds that are just messing it up. The combined energy climbs from moderate (173) up to strong (1003), but it’s all for nothing with that wind texture. Thursday morning the 17th looks clean with a cross-offshore breeze from the southwest, but with the swell at 6ft and that moderate energy (563), it’s still not making the grade for a proper session.

The best chance we’ve got in this whole run is shaping up for Friday afternoon the 18th. That’s when a proper groundswell shows up, with a long 13-second period from the west-northwest pushing 7ft of swell. The combined energy jumps to a solid 1380. The wind will be cross-offshore from the west, which should keep things reasonably clean. This is the standout, but it’s a short window. The following morning, Saturday the 19th, still has some decent 5ft swell at a 12-second period with clean cross-offshore wind, but the energy drops off (569). It’s a secondary call, not the main event.

Sunday the 20th morning is actually worth a look, too. The wind is a light cross-offshore from the southwest, and with 5ft of west-northwest swell at 10 seconds, it’ll be clean but nothing special. Combined energy sits at a moderate 487.

After that, things taper off pretty hard. The first week of the run fades into small, weak surf with poor winds. A tiny blip on Monday the 21st morning has a 13-second period groundswell at 4ft, but it’s cross-shore with barely any wind. It’s a long-period wave that would be better suited to a point or reef, and Trestraou is a sheltered spot that prefers a different direction, so it’s a miss.

The second week is basically a write-off. From Monday the 22nd onwards, the swell is small, often under 3ft, and the wind is either onshore or strong cross-shore. There’s no quality on offer. It’s one of those blank runs that happens now and then.

So to wrap it up: your best bet is Friday afternoon the 18th, with a backup on Saturday morning the 19th and maybe Sunday the 20th morning. The rest is a washout.

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.
