Duplantis misses world record but on track for Olympic title defence
The Swede, who broke the world record for the eighth time with a vault of 6.24 metres in April's Xiamen Diamond League meet, cleared 6.00 with his first attempt. His closest challenger, American Sam Kendricks, cleared 5.95.
Duplantis had three failed attempts at 6.25, though conditions did not help.
"I like where things are at and I know that I can be just even that much a little better for the Olympics in a month," Duplantis said.
Asked if the windy weather was a factor he said: "I just probably needed a tiny bit more grip a little bit more depth. It's very difficult and it demands for me to be pretty much perfect to make a world record.
"I'm going to go back to Stockholm and do some training and then if I'm able to take care of business and win the Olympics in a month then it's going to be a lot of wine and all that good stuff that you can get here in Paris."
