If the US-Mexico game goes off at Rio Tinto Stadium as has been reported, Mexico will likely face its most difficult regional opponent in challenging weather conditions.
According to weather.com, the daily average temperatures for Salt Lake City on Feb. 11 are 42 degrees and 29 degrees, respectively. That is, the average high on Feb. 11 has been 42 degrees and the average low has been 29. Not sure how far back it goes, but it goes back at least 20 years.
Over that time, the record high has been 55 (in 1987) and the record low has been 19 (in 1989). The average sunset time has been 5:57 p.m. as well.
Needless to say, it will be biting cold that day. And having been to Rio Tinto, I can say that there is hardly anything obstructing wind from getting into the stadium. It sits right at the base of a mountain range and if the winds whip through there, the stands will hardly provide any cover. From the street leading into the stadium, you can see pretty much the entire field. The one level of stands will hardly do anything if any wind picks up around the venue.
