Male grooming brand Old Spice announced its Fifth Annual Top-100 Sweatiest Cities List — a ranking of the nation’s heaviest sweaters during the summer months. For the third time in four years, the No. 1 perspiration producer is Phoenix. The top honor also went to the famed desert city in 2005 and 2003.

The city’s average high temperature last year was 93.3 degrees — compared to a cool 63.2 degrees for San Francisco, the nation’s least sweaty city. In recognition of its top placement on the list, Phoenix Mayor Phil Gordon receives a a year’s supply of Old Spice Red Zone antiperspirant.
