The event is the brainchild of Korvanappiliitto ("the Earbud Society"), which has been around for only a year. Its mission is to invent and conduct new events in Kuopio.
According to the organizers, talking about the weather is the foundation of Finnish conversation.
"As far as we know, similar events have never been held anywhere else before. Well, is there anything more Finnish than a discussion about the weather? Anyone is free to take part in the championship. Finns are no established masters of small talk, but now we'll spare them at least the necessity of thinking up other topics of conversation," Korvanappiliitto Vice President Mari Väänänen told Finnish national broadcaster Yle, implying that it will be a fun event.
Meanwhile, Finland is known as the homeland of a number of sports many would consider "oddball."
In addition to competitions that risen to more or less international fame, such as the Air Guitar World Championships, the lists of more obscure championships pioneered by Finns include Swamp Soccer, Wife Carrying (with the winner receiving the wife's weight in beer), Mobile Phone Throwing and Berry Picking.
Other noteworthy mentions include the Mosquito Killing World Championships, which have been held since 1995, and the World Sauna Championships, which were contested until 2010 when a competitor died of third-degree burns.
While today's Finland is mostly seen as a winter sports nation excelling in skiing, it used to be a major track and field contestant in the pre-war decades. During the golden age of Finnish elite sports, the Nordic nation produced such champion long-distance runners as Paavo Nurmi and Hannes Kolehmainen, who achieved heroic status in the homeland, not least for embodying the Finnish trademark concept of 'sisu,' which roughly translates as a combination of persistence, determination and boldness.
