When I arrived the day before, I was welcomed by a strong, cold wind so I thought I might have to wear my woolen jumper and socks in the sandals early morning. However, looking out the window, I saw frost and 10 cm snow so I had to find all my winter clothes and sneakers. It was about 5C when I left at 8.30 and though the temperate increased to 15C mid afternoon, the strong headwind made me keep the warm clothes on all day...
