Alright, so I was planning a trip to Lyon, France, this December. Naturally, the first thing I did was check the weather because, you know, gotta pack right. Winter in Europe can be unpredictable, but I wanted to get a sense of what I was in for.

I started digging around for info on Lyon’s December weather. I found out that it’s pretty darn cold. We’re talking average highs of around 44 to 47 degrees Fahrenheit (that’s about 7 to 8 degrees Celsius for my metric friends). And at night? Don’t even get me started. It drops to an average of 33 Fahrenheit (around 1 degree Celsius). Sheesh! Better pack those thermals.
One thing that was kind of consistent across different sources was that the temperature decreases throughout the month. So, the beginning of December might be a tad warmer than the end, but overall, it’s chilly.
Here’s the Breakdown
- Average high temperatures: Around 44-47°F (7-8°C).
- Average low temperatures: Around 33°F (1°C).
- Overall vibe: Cold.
I kept looking, and it turns out December is also the month with the shortest days in Lyon. So not only is it cold, but it’s also dark early. Good to know, I guess.
I even found a source that said to “expect Lyon December temperature around 8°C (47°F).” Well, that’s in line with what the others said. I guess that means it’s pretty accurate.
After gathering all this, it was clear that I needed to pack some serious winter gear. I’m talking warm coats, scarves, gloves, hats, the whole nine yards.

So, yeah, that was my little adventure into researching Lyon’s December weather. It may be not exciting stuff, but hey, it is really important when you are planning a trip. Stay warm, folks!
