Yesterday we had a very cold day here in Stuttgart.
The night temperature was according my thermometer -9°C. During the day the temperature went up to between -4,5°C (shadow) to + 1°C. The sun was shining and I used the midday ours to cut some wood.
Just by the way I took a look at the local spot with Podarcis muralis (introduced population) and surprise….
