All weather conditions have unique effects that can sporadically occur during or after games. These effects can impact individual players up to whole Teams, and range from positive, to negative, to birds. New weather patterns are known to emerge in response to the unfolding events of Blaseball each season. With the introduction of Ballparks, it became possible for Fans to influence the weather by renovating their stadiums to increase the likelihood of a specific weather type.
