B: The weather in London can change a lot in a day. You can have four seasons in one day. In the morning, the weather is warm just like in spring. After an hour, black clouds come, and then it rains hard. As soon as the rain stops, the sun comes brightly, so in winter they can swim sometimes. In the later afternoon the sky will be clear, and the weather gets a little cold.
