The German Weather Service calculates the probability in the period from June 10 to 12 at 80 percent. There is also no guarantee that the polar air will bring ground frost, but temperatures below ten degrees Celsius are quite possible.
Shepherds, on the other hand, usually do not shear their sheep until the end of June, so that the animals, especially the lambs, do not have to freeze without their thick fur. So far, the weather outlook for the period in June 2023 is quite good, it should be relatively warm.
