Does the weather in South Africa change greatly, sometimes hot and sometimes cold?

During the World Cup in South Africa, it was winter, and the influence of climate on players' performance could not be ignored.

Playing football in winter is the coldest. Because it is located in the southern hemisphere, South Africa is in winter during the World Cup, and the highest temperature generally does not exceed 20 degrees Celsius, and the lowest temperature will drop below 10 degrees Celsius. However, the temperature difference between day and night in some cities can even reach 20 degrees Celsius. Such a large temperature difference can easily cause respiratory diseases. In the past, under such weather conditions, it was not uncommon for players to catch a cold and feel unwell.

Precipitation is unpredictable and troublesome. The southern coast of South Africa has a typical Mediterranean climate, with wet and rainy winters. Precipitation in most other areas is very unstable. The average annual rainfall in South Africa is 450 mm, which is only half of the global average rainfall. The average annual rainfall in arid areas in the west is less than 200 mm. Generally speaking, there will be periodic droughts in South Africa, but after the droughts, there will be frequent floods, which are unpredictable.

Strong ultraviolet rays harm the skin. South Africa is sunny in winter. Except the humid air in the south, generally speaking, due to the low moisture in the air and high ultraviolet index, facial skin will become rough and dry, and even skin damage will occur. If sunscreen products are used, the SPF must be at least 15.

Altitude 1800 meters, easy to be afraid of heights. Most of South Africa is a plateau over 600 meters above sea level, while Johannesburg, which will host a series of key events such as the finals, is nearly 1800 meters above sea level, and most other stadiums are also above 1000 meters above sea level. The higher the altitude, the greater the physical exertion of players during the game, and the easier it is to get tired. Although high altitude has no significant impact, the team must take this into account.

France, Italy and other teams set their pre-competition training camps at higher altitudes, while South Korea and Japan use special equipment to simulate high-altitude environments ... How effective are the teams in adapting to high altitudes? We will know in a few days.
