Explain the reasons why London chose to hold the Olympic Games in July and August from the perspective of climate.

The climate type of London is temperate maritime climate. During the Olympic Games, in July and August, the climate in this area is mild and rainy.

London is influenced by the North Atlantic warm current and the west wind, and belongs to a temperate maritime climate, with small temperature difference among the four seasons, cool summer, warm winter, humid air, rainy and foggy, especially in autumn and winter.

The temperature in London in summer (June-August) is around 18°C, and sometimes it reaches 3°C or higher. In spring (end of March-May) and autumn (September-October), the temperature is maintained at around 11-15 C. In winter (November-mid-March), the temperature fluctuates around 6 C. There are rare cases of freezing in winter in London, but wet and cold air can make people catch 2-3 colds in a winter.

London can be visited all year round, but some tourist attractions will be closed or their opening hours will be shortened in winter. It is usually open when the weather is good. July-August is the peak season for sightseeing in London, but in these months, there are not only uncertain sunshine, but also crowded people and inflated prices.
