    Why Yokohama Stadium plays differently

    Yokohama Stadium sits a few hundred metres from Yokohama Bay, so the afternoon sea breeze is a regular feature and humidity off the water is constant through summer. During typhoon season (August–October), approaching systems can force schedule changes days in advance.
