The Lowdown

Alright, folks, Rusty here. Let’s be straight with you – this 16-day stretch for La Tranche sur Mer is a tough one to get excited about. We’re looking at a whole lot of small, weak swell and a forecast that just doesn’t want to line up. You’re gonna have to be patient, and honestly, for the next week or so, you might be better off finding something else to do. We’ve got a long gap of nothing but ankle-biters and knee-high slop coming up, so don’t hold your breath for any heroics.

The first week is basically a write-off. From the 6th through the 12th, we’re talking about waves mostly under 2ft with weak energy readings, mostly in the low single digits and teens. The swell direction is coming from the west, which is fine, but the size just isn't there. The water temp is 70°F, which is about average for this time of year, so at least you won't be freezing while you're sitting there staring at nothing. There’s a day or two of clean, glassy conditions, like the morning of the 11th, but there's nothing to ride. It's heartbreaking, really.

Things pick up a tiny bit starting Thursday the 13th. We finally see some more life in the water, with the swell pushing to 2ft in the morning and the energy climbing a bit. It's still very ordinary, but it’s the first sign of something. By the afternoon, the swell jumps to a full 3ft with a long 11-second period from the west, and the energy finally gets into the triple digits at 351 – that's a taste of moderate energy. It's raw and unorganized, but it's something. Friday the 14th keeps that small but fun-sized energy going, with a clean, glassy morning showing 2ft. Just don't expect much.

If you're looking for the one small window that might offer a glimmer of hope, it’s that afternoon of the 13th. The swell is the biggest we’ll see for a while at 3ft from the west-northwest, and that long period gives it some push. The wind is cross-offshore, keeping it reasonably clean. It’s not going to be epic, but compared to everything else, it’s the standout. The second week is more of the same: small, weak pulses of west swell, with the energy occasionally pushing up to moderate levels. The 17th has a bit of size in the afternoon with 2ft and energy at 109, but the 30 km/h fresh breeze will chop it up. After that, it just fades back into the grey.

So there you have it. A long, drawn-out period of small surf, with one slightly-better-than-ordinary afternoon on the 13th. Keep your expectations low, and maybe give the kites a thought, because with this much weak swell and wind, that might be more your speed. This is Rusty, signing off.

A general guide to surfing at La Tranche sur Mer can be found by selecting the local surf guide option on the grey menu.

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 La Tranche sur Mer 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.
