IOC president Jacques Rogge claims even the great British weather will not dampen the enjoyment of the London 2012 Olympics.
The Games could be one the wettest of any summer Olympics if the rain continues and weather forecasts are predicting at least some downpours.
But Rogge said that he was not worried about the poor summer weather having an adverse effect.
He said: "I would definitely prefer the Games in brilliant sunshine rather than rain but it is nothing fundamental.
"There might be some issues for Wimbledon and the tennis as most of the matches are not under the roof. That might need some rescheduling but Wimbledon has great experience in that.
"It might influence the sprint competitions a little bit if it is cool and humid but it is nothing fundamental."
