In England, people often talk about the weather because they can have four seasons in one day. In the morning it is warm, just like in spring. An hour later, black clouds come out, and then it begins to rain and gets a little cold. In the afternoon the sky may be clear, and the sun may begin to shine. It may be just like a day in summer.
You can also have summer in winter, or have winter in summer. So in winter you can sometimes swim, and in summer you can sometimes wear warm clothes. When you go to England, you will see some Englishmen take an umbrella or a raincoat with them on a sunny morning. But you'd better not laugh at them. If you don't take an umbrella or a raincoat in the morning, maybe later you'll have to walk in the rain. People often say that in England you can have four seasons in one day. Sometimes you may feel you have the same season all the year round.
