THE WEATHER IN THE SOUTH
Spring and summer are very sunny in the south. The sun shines brightly and it is usually very hot. The temperature in summer is about thirty-thirty- five degrees above zero and even more in many places. But when the sky becomes cloudy and a strong wind begins to blow from the sea, it is cool.
In late autumn and in winter the weather is usually rainy. In winter it doesn’t often snow and the snow doesn’t lie on the ground for a long time.
Grass, trees, flowers and vegetables grow very well in the south.
The swimming season on The Black Sea coast lasts from the end of May to November.
