Welcome to England! The weather of England is very changeable.
It can be rainy, sunny, windy, warm, foggy or cold at any time of year. If it’s raining when you get up in the morning, it can be hot and dry by the afternoon. The west of England is wetter than the east, and the north is cooler than the south. Just be ready for any kind of weather.
In England, shops are usually open from 9:00 am to 5:30 pm. On Sundays, some shops are open from 10:00 am to 4:00 pm. But a lot of shops are closed. Banks, museums of other places are open from 10:00 am to 5:00 pm. You can go to the parks at anytime.
All the cities have buses, trains and taxis. People wait in line for buses and they are unhappy if you push in at the front. Don’t forget this---traffic goes on the left.
Be careful!
