@iantila It's been 14°C while being very sunny in the morning when I took the decision and peaked with 17° in early afternoon. I'm not sure if I'm representive, but I haven't been the only one in shorts outside.
Today the temperature was ~2° lower, but cloudy, and I started the day over enthusiastically with jorts again but later switched back to long jeans because it felt too cold.
Aaah right, I assume that's this warm spring-y wave we went through last weekend.
17° is reasonable to shorten the leg sleeves.
It got quite chilly again, wearing shorts right now sounds pretty adventurous.
