Heavy Rain

Heavy rain always happens when the water or vapor condenses in the warm and damp air. Besides that, some other atmosphere phenomena cause heavy rain such as low-pressure zone, hurricanes, etc. It is dangerous to play soccer in the heavy rain. As we know, the sliding shoveling action in soccer is potentially dangerous. Heavy rain causes the field to get more slippery, so the action of sliding shoveling increases the possibility of hurting others. In addition, heavy rain may lead to the appearance of puddles in the field, so soccer gets less resilient.

Lightening 

The formation of lightning is generally accompanied by the appearance of thunderstorms. The small ice crystals and graupel collide with each other in the thunderstorms, and graupel carries a negative charge toward the bottom of the storm as the graupel falls. In 1998, there was a severe casualty that happened in Congo that lighting killed ten soccer players(report links to an external site.). They were playing soccer, and there were no tall buildings nearby, so they were the tallest in the field and struck by lightning.

Wind

The way I see it, the wind has no potential danger to the soccer players. But if the wind is extremely strong, it can cause the trajectory of soccer to get unpredictable. For the goalkeeper, it is harder for them to make a saving. And for the other players, also cannot ensure the accuracy of their passing.

Hot Weather

The weather in Vancouver was quite cool even in summer, so players in Vancouver have no necessary to worry about this hazard. However, somewhere near the equator, its temperature of it will be extremely high. This can lead to heatstroke in athletes with insufficient hydration. In addition, strong sunlight can also cause damage to people's vision.
