Despite health concerns included in an official report before the vote, the FIFA executive committee opted for the tiny emirate's bid in 2010. Blatter has repeatedly refused to say if he backed Qatar, which can have temperatures of 122 degrees during the summer.
The head of the local organizing committee, Hassan Al-Thawadi, said Qatar bid for a summer tournament. However, he but left open the option of a switch to another time of the year.
"It there is a wish from the football community to move the World Cup to the winter, we are open for it," said Al-Thawadi, who spoke to the conference through a live video connection
In May, Blatter said in an interview with a French newspaper it would be "not rational and reasonable" to stage the first World Cup in the Middle East in the summer.
Moving the tournament to the winter would have a major impact on the schedule of European soccer leagues, which would have to change things for at least one season.
