People think that the British like talking about
the weather. It's one of the most famous
stereotypes about England. Your conversation
will be boring if you start it with this topic. They
don't talk too much about it but they still rely on
the weather forecast.

We usually imagine the United Kingdom as a
foggy and rainy country. But in fact, the weather
is very changeable there. You wake up and see a
clear sky through the window. Then you go to
brush your teeth and it's already rainy. A bright
morning sky can easily change into a wet slushy
afternoon. That is why in every office, library or
cafe they have umbrella stands. British people

usually carry umbrellas with them.

It's better to travel to England at the end of
summer and in early autumn. It seldom rains.
The temperature is warm. July and August are
the sunniest and most pleasant months. A lot of
people go to the south coast of England to
enjoy sunny days near the ocean.
