July 1999 was the warmest July on record at the marina within Atlantic City with a monthly mean temperature of 78.6 degrees. The previous record was 78.1 degrees set in 1993. July 1999 was the second warmest July on record at the Atlantic City International Airport with a monthly mean temperature of 78.6 degrees. The warmth was not confined to urban areas.
