…. is NOT so warm that you could be sitting in the garden naked in January or February. At night, the temperature regularly drops below zero, and during the day it varies between 5 and 20 degrees. The difference is the SUN: when it shines, you can walk around in your T-shirt, but when it is cloudy or even raining, you need a thick jumper, a thick jacket or more.
What is noticeable, though, is that the number of days with T-shirt weather is still greater: even in January and February, we regularly had lunch outside or sat in the sun in front of the house. Our “lease cat” Geert Mak shows this beautifully: sleeping in the sun on a cushion in a tray of kindling on top of the pile of wood for the fireplace!
