The Via Francigena from Calais to Lausanne takes you through various regions of northern France into Switzerland. Starting in the coastal area of Calais, the temperatures in October are relatively mild, with average highs around 17°C and lows around 13°C. Expect moderate rainfall, often in the form of rain showers, with occasional sunny days breaking through the cloud cover.
As you move inland towards Arras and Reims, the weather becomes slightly cooler with average highs between 15°C and 16°C and lows dropping to single digits, around 8°C to 9°C. The rain remains consistent, with patchy rain possible on many days. Overcast skies are frequent, but you might also experience partly cloudy or sunny weather.
Continuing southward, nearing the border with Switzerland around Langres and Champlitte, temperatures continue to drop, with average highs around 10°C to 12°C and lows nearing 5°C. The weather is characterized by overcast days interspersed with periods of rain, ranging from moderate showers to heavy rain at times. Sunny days become less frequent, and the likelihood of rain increases, making it necessary to be prepared for wet conditions.
Finally, as you enter the Switzerland and approach Lausanne, the temperatures remain cool with highs around 9°C and lows around 3°C. You will experience a mix of sunny and partly cloudy days, but the region is also susceptible to rain showers, with occasional freezing rain or light snow as the landscape begins to hint at the coming winter.
