Lyon weather relies on the city’s location in the Rhone-Alpes region of southeastern France.
The city has cold winds blowing in from the eastern Alps, as well as warm breezes that arrive from the southeast and the Mediterranean Sea. This combination creates a temperate climate in Lyon throughout much of the year. It is also worth noting that the precipitation in Lyon can be unpredictable. While autumn is the season when you will encounter the most rain in Lyon, any time you travel to Lyon, go prepared with the right gear for potentially wet weather. When you think about Lyon weather, the best time to visit Lyon should be largely informed by what you are interested in doing when you arrive.
Winter is the driest season in Lyon and does not experience as much snow and sleet as you might imagine for a town near the Alps. It is markedly colder than the rest of the year, due largely to its inland position. The average temperature in the winter in Lyon is around 37 degrees Fahrenheit. January is the coldest month and the temperatures go up from there until the weather begins to improve in the early spring. Winds from the Alps make for biting cold on the more extreme days.
Spring sees average temperatures in the mid 50s by March. By May, the average temperature hovers right below the 70-degree mark.
