I'm watching the game right now on BBC Sport, the one with English commentators (Emlyn Hughes, Terry Venables etc). All the fans are wearing short sleeve t-shirt, this indicates that the temperature is between 20C-24C. Mexicans are very sensitive to cold, so most of them wear jumpers when it's below 20C.
