In brief: No

The scrotum is designed to be a cool safe haven for sperm.
Hot tubs, hot pants are associated with poor sperm quality; it is unlikely/improbable that men are more fertile in hot weather. That is not to say that they are infertile in hot weather or more fertile in cold weather. The sperm prefer cooler temperatures, since they are the source of male fertility, they need to be happy-cooler is better.
