on the field which have been measured at 115 decibels—just short of the threshold of pain. The enclosed playing area also enhances the effects of Gainesville's warm and humid fall climate. Game-day temperatures at field level have been known to exceed 100 °F (37 °C), creating a swamp-like atmosphere. (This was the impetus for a University of Florida researcher, Robert Cade, to develop Gatorade as a way to combat dehydration.) Furthermore, during hot and sunny day games, Florida's sideline (on the stadium's west side) is in the shade provided by the press box, while the visiting team's sideline (on the stadium's east side) is exposed to the sun. Florida fans are loyal (having sold out every home contest from 1979 until 2011) and loud, thus creating a tremendous home field advantage for the Gators. The size and exuberance of the home crowds, when combined with the stadium's close-in design of the seats, concentrates the fan noise at field level, making the Swamp one of the loudest stadiums in America. In 2019, Auburn coach Gus Malzahn said that the Swamp was louder than LSU's Tiger Stadium, and amongst the top two loudest stadiums he's ever been in. On 30 November 2019, in a game vs. Florida State, the decibel level in the swamp exceeded that of CenturyLink Field, home of the NFL’s Seattle Seahawks, which is among the loudest in the NFL. Combined, these factors create an intimidating environment which can rattle and disrupt opposing teams, making it difficult to hear playcalls and execute assignments. Florida Field has been repeatedly ranked by various publications as being the toughest stadium in which to play for opposing teams. Florida's performance at home illustrates this effect. In a 20-year span beginning in 1990 (when the north endzone expansion was completed), Florida posted a 113–13 overall home record, which was the best in the nation during that period. They were particularly dominant under Coach Steve Spurrier. They went undefeated at home from the time Spurrier arrived in 1990 until 1994, and lost only three SEC home games during Spurrier's 12 years in Gainesville. Top attendance Florida Field traditions Like most historic college football venues, the Swamp has several notable features and is the scene of several unique game day traditions: Commemorated atop the south end zone's facade are the years of each of the team's Southeastern Conference championships and its 1996, 2006 and 2008 National
