Attendance at the 45th New Orleans Jazz and Heritage Festival, which featured some of the mildest and sunniest weather in Jazz Fest memory, increased by 10,000 over last year’s figure, a gain of about 2 percent.

Festival officials reported 2014 attendance totaled 435,000, up from 425,000 last year.

Jazz Fest wrapped up Sunday, after seven days — spanning two weekends — of sunny skies and relatively mild temperatures. In 2013, three days of rain left much of the Fair Grounds Race Course infield covered with mud, likely reducing attendance.

Though this year’s edition featured popular acts such as Bruce Springsteen, Eric Clapton and former Led Zeppelin frontman Robert Plant, the festival’s 2014 numbers were still behind 2012’s estimated 450,000 attendees.

Jazz Fest doesn’t release daily attendance or audience estimates for individual performances.

Next year’s Jazz Fest is scheduled to begin April 24 and conclude May 3.

The nonprofit New Orleans Jazz and Heritage Festival and Foundation Inc., which owns Jazz Fest, uses proceeds from the festival to fund year-round activities in education, economic development and cultural enrichment.

Its education programs include the Don “Moose” Jamison Heritage School of Music and the Tom Dent Congo Square Lecture Series.

Economic development initiatives include Community Partnership Grants and the Sync Up entertainment industry conference.

The foundation’s cultural events include free community festivals such as the Crescent City Blues and BBQ Festival and the Congo Square New World Rhythms Festival.

The foundation also owns community radio station WWOZ-FM, the Jazz and Heritage Archive and the George and Joyce Wein Jazz and Heritage Center, an education and community facility scheduled to open this fall.
