The Meetic dating agency, based in Boulogne-Billancourt, France, said its study indicates Norwegian men were the most likely to have had summer romances, followed by Spaniards and Italians, The Local.it reported Thursday.
Maria Garay, dating coach at Meetic, said only slightly more than one in 10 of the summer romances lasted to the six-month mark.
"A sense of humor is key for a summer relationship to live on," she said.
Meetic did not say how the study was carried out.
