In two weeks, the Sun will cross the celestial equator marking the beginning of astronomical autumn in the Northern Hemisphere. Astronomical changes will inevitably lead to weather changes.
The average daily temperature starts to decrease. The sky gets more overcast, short and heavy rains turn into long drizzle. Night frost becomes more frequent, with the mercury falling to +10 at night even in the south. Thunderstorms are replaced by thick fogs. A snow cover begins to form in the north and in the mountains.
Along with atmospheric changes, nature is also changing. Birds gather in flocks and prepare their young for long-distance flights. Chlorophyll is destroyed in leaves and they turn yellow, red and purple. Water bodies cool down, and fish become more active to store enough fat for winter. There are less insects. Meadow flowers fade. Nature slows down and prepares for a long winter sleep.
