The weather on the Voie d'Arles often changes from hot and sunny, to rainy and cloudy.
Beginning in Arles and going west, you should expect a lot of sun because of the Mediterranean climate. To Montpellier, day temperatures can get up to 29 degrees Celsius, and night temperatures drop to around 19-21. There might be light rain, but it won't be much.
Then up to Toulouse, the weather doesn't change much. It usually stays sunny and temperatures are stable. In Baziège, however, there might be heavy rain sometimes.
Past Toulouse towards Auch, there are fewer sunny days. Expect more cloudy days, light rain, and even some heavy rain.
The last part of the path past Auch to Somport is in the mountains. Here, weather changes often. Sunny days may turn into moderate or heavy rain. Temperatures are cooler, getting up to 22°C during the day and dropping to 12°C at night.
Overall, the Voie d'Arles has mostly warm and sunny weather, but there could be some heavy rain, particularly in the mountains.
