Hi, I will be travelling to China and in Beijing I am from 23th-25th May.

the weather forecast for those days are different on various weather site, max temperature 34-35 on this site , and 41 -42 on other site. What really I can expect ? I ( 70 years old ) am planning to visit Badaling Great Wall, Forbidden City, Tian'anmen Square and Summer Palace. All this are outdoor activities. What do You recommend , what clothes , maybe umbrella for a sun protection ??
