The NFL has various requirements for potential host cities. The most difficult one for Seattle to meet might be the weather. For outdoor venues such as the Seahawks' CenturyLink Field, an average temperature of 50 degrees in February is required. According to the television station, the temperature in February averages 44 degrees in Seattle. However, the league could waive the weather requirement, as it's doing for the 2014 Super Bowl in New Jersey.
