Plenty of pro sports have variation in conditions. World Cup soccer is played outdoors with rain, heat, whatever. Rain matters even more in Le Mans, where time records are being set. It doesn't really matter as long as it's cool to watch.
We've just finished Copa America, where players and managers complained about the pitch and its dimensions.
In baseball too, you have things like playing in LA or NY vs playing in Denver with thin atmosphere that completely affects movement of pitches as well as how well they fly through the air.
