and it depends what wind direction is, from south or north. I can wear shorts n t shirt even in late september. Depends year from year. Last september I did fish in shorts n n t shirt , sun was warm and it was maybe 14 ¤ C

Not at home, outside atm shorts and t shirt. Nothing more, I can go like that until +16¤C .... Jeans if its undere, I can have t shirt if its 14-15 ¤C then light jacket.
