First few days was cloudy/misty/cool, as you can probably tell from the pics.
I didn't take any pics on Pas de Peyrol for that reason - it was very foggy and chilly at the top. Likewise on Col de Croix St Robert, it was very windy and rainy on the way down. I was shaking with the cold and needed two large coffees plus early lunch in the next town to continue, despite wearing light rain jacket and gilet under that (plus jersey and base layer). Someone mentioned 11oC at the top, I think? The second part of the week was just perfect for cycling, with temperatures in the 20s - sometimes too warm on the climbs in the afternoon, but fine on the last day when I wore my new 999 Miglia kit, which is lightweight for summer, and no gilet was required on all but the longest descents. It was too windy at times-especially when a headwind! But the last day's weather was just perfect summer weather, with lizards running across the roads, and butterflies flitting around. Generally the route had very little traffic.
