Every season has its own charm and is good in its own way. My city is situated in

southern part of Kazakhstan and we have four seasons here: winter, spring, summer and

autumn

My favorite one is summer. Summer is the hottest season in the year. It begins in June

and ends in August. In summer the sky is clear and cloudless. The days are long and the

nights are short and warm. When it is hot I can swim in a nearby river. I like to swim, lie

in the sun, and play outdoors in summer. The weather is usually fine. Sometimes it rains.

But the rains are usually warm.

Autumn comes after summer. It brings heavy rains and winds to our region. Honestly, I

don't like autumn. The days are becoming shorter, the sun loses its force. It often rains. It

is the season of harvesting. It's muddy and gloomy outside. But it's a tasty and beautiful

season. Because there are a lot of fruits in autumn: apples, pears, grapes, plums. The

leaves are red, green and yellow and they fall down from the trees.

Winters are mild here. The first snow falls at the beginning of December. It quickly

melts though. It is getting colder day by day. The sun shines rarely but everything looks

so pretty covered with snow. My friends and I go skiing, sledding or snowballing on such

days.

Spring starts with sunshine and warm winds. The snow starts melting the birds start

singing their charming songs, trees start blooming, and there are lots of tulips and poppies

around.

I think all seasons are beautiful.
