Climate Chart of Lyon, France

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperature is lowest in January, at 4.2 °C, and reaches its highest point in July, at 23.2 °C. These are averages for each month, not daytime maximum temperatures, so they do not show the full range visitors may experience within a day. Across the calendar months, the unweighted mean of monthly mean temperatures is 13.2 °C. It provides a single summary of those monthly averages, rather than a day-weighted annual temperature.

Rain

Mean daily rainfall is lowest in February, at 1.79 mm/day, and highest in October, at 3.25 mm/day. The figures describe average daily amounts within each month, not monthly totals; they also cannot show how often rain falls or whether a particular visit will be wet. The unweighted mean across monthly mean daily rainfall values is 2.37 mm/day. This is a broad summary, not a forecast or a measure of the distribution of rainy days.

Sunshine

Mean daily sunshine reaches its highest value in July, at 12.28 hours/day, and its lowest in December, at 4.44 hours/day. These averages can help set expectations for sunshine duration, but they are not measures of daylight length and do not guarantee the conditions on a given day. The unweighted mean of monthly mean daily sunshine duration is 8.52 hours/day, a summary across the calendar months rather than a day-weighted annual figure.

Snow

The highest monthly mean daily snowfall is recorded in January, at 1.72 mm/day. The unweighted mean across monthly mean daily snowfall values is 0.46 mm/day. These daily averages do not establish how many days have snow, snow depth or snow cover, and they cannot indicate skiing conditions.

Best Travel Time Guide for Lyon, France: Ideal Seasons and Weather Insights

If lower average rainfall is a priority, February is the option indicated by the lowest monthly mean daily rainfall, 1.79 mm/day; this does not guarantee dry days or tell you how frequently rain occurs. Pack rain protection with the higher-rainfall average in mind if travelling in October, when mean daily rainfall is 3.25 mm/day. For visitors prioritising cooler monthly averages, January is the coolest month in the supplied temperature data, with a monthly mean of 4.2 °C. This is not a daytime high, so plan for variability rather than treating the average as a daily forecast.

For outdoor sightseeing planned around average sunshine duration, July has the highest mean daily sunshine at 12.28 hours/day, while December has the lowest at 4.44 hours/day. Sunshine duration is not day length, and these monthly averages cannot guarantee clear skies; rainfall and temperature preferences may point to different months rather than one universal best time to visit. Snowfall is part of the recorded monthly averages, with the highest mean daily amount in January at 1.72 mm/day. This average alone does not indicate snowy-day frequency, snow cover or conditions for snow-based activities.
