La Tranche sur Mer Surf Forecast and Surf Report

Alright, Rusty here again. Let’s break down the same outlook but in feet and miles per hour.

Well, to be blunt, the next couple of weeks look pretty weak for La Tranche sur Mer. The surf is going to be small and mostly unremarkable. The water is sitting at 72°, which is much warmer than the usual this time of year, so the wetsuit can be a thin one.

We start on Wednesday morning, the 9th of September. There’s a small 3ft swell from the west, with a period of 9 seconds, and a light offshore breeze from the NNW. The combined energy is moderate at 157. It’s rideable, but it’s nothing to get excited about. The afternoon brings a fresh offshore wind from the WNW at 19 mph, but the quality drops and it’s poor.

Thursday the 10th is a total washout. The swell drops to 2ft in the morning, with an onshore breeze from the ESE. The energy is weak at 56. The afternoon is even smaller at 2ft with a cross-offshore wind. Don’t bother.

Friday the 11th of September has a glassy morning. The swell is tiny at 1.0ft from the west, but the period is a long 11 seconds. The energy is weak at 44. It’s clean, but you’ll be hard-pressed to get a wave. The wind goes cross-offshore in the afternoon.

Saturday the 12th is a repeat: glassy and clean, but the swell is only 2ft with a short 8-second period. Energy is weak at 47. It’s a longboard-on-the-glass morning.

Sunday the 13th is the only real standout. The morning has a 2ft west swell with a very long period of 13 seconds, and a light cross-offshore breeze. The energy is moderate at 153. But the real highlight is Sunday afternoon. The swell bumps up to 3ft from the west, with a period of 12 seconds, and the wind is offshore from the WNW at 16 mph. The combined energy jumps to a strong 434. This is your best bet. The break is a beach/jetty, so it’s exposed and will handle the swell. The long period will create some proper lines. The wind will keep it clean. The conditions are marginal with questionable tide, but this is the time to be out. Crowds are possible, so get there early.

The next week is a drought. From Monday the 14th through Tuesday the 22nd of September, it’s mostly small, weak, and messy. There are a few afternoons with clean offshore winds, like Monday the 14th afternoon and Wednesday the 16th afternoon, but the swell is tiny and the energy is low. The wind is often cross or cross-onshore, making it choppy. The 16th of September afternoon has a 3ft swell from the WNW with a period of 10 seconds and a cross-offshore breeze, with energy at 227, but the conditions are still marginal.

The 19th of September has a bit of energy in the morning with a 3ft west swell and a 13-second period, but the wind is cross-onshore, making it choppy. The afternoon cleans up with a cross-offshore breeze, but the swell drops to 2ft.

The final days, from the 22nd to the 24th, are all poor. The wind is either cross-shore or cross-onshore, and the swell is small. The 24th of September has a 3ft west swell with an 11-second period, but the wind is a fresh cross-shore at 19 mph, making it lumpy.

So, take it from me: if you’re not in the water on Sunday the 13th, you’re probably not surfing. The rest of the outlook is a write-off. It’s a lean stretch, but forecasts can change, so keep checking back.

Rusty.
