All Saturday and Sunday, the sky over Bolesławiec was gray-beige, and the Sun looked as if seen through a smoked window. There was a slight haze-like mist in the air.
It is dust from the Sahara. Sand traveled here with strong winds from the desert.
There are countless particles floating in the air. After a longer walk, you could feel them in your mouth and nose.
Things should improve from Monday: the dust will settle and the air will become clearer.
