That depends on what you mean by hot: the highest temperature ever recorded in Mexico City is 38C, so my friends from northern Mexico and from, say, Arizona would say that no, Mexico City does not have even a day or two when it gets hot. (Of course, 38C is probably much too hot for comfort if you are playing football.)
But back to June 22, 1986.
I'm pretty sure the Mexican national weather service knows exactly how hot it was on June 22, 1986 in Mexico City, but unfortunately their website doesn't seem to have day-by-day data available for download (at least not that far back). I did find a table of monthly average high temperatures [1], and for June 1986 in Mexico City (see "Distrito Federal" in the table) the average high temperature was 23.6C. The Weather Underground says that on June 22, 1986 the highest temperature was 75F [2], which is 23.9C. (Why doesn't the Weather Underground default to Celsius for visitors from Mexico?)
So it looks like I would have won my (very conservative) bet that the temperature was somewhere between 15C and 25C that day.
> Maybe the TV commentator said it was a hot day.
This is definitely possible!
1. The commentator could have assumed that because the game was in Mexico it would be hot! This happens all the time. I have explained to dozens of people that Mexico City doesn't really get hot, most are surprised. Of course, when I remind them Mexico City is at an altitude of 2.2km they usually believe me about the lack of heat.
2. The commentator could have known it was 25C and still thought that was hot for a football match.
