Common sense would tell you that when it is scorching hot, you should not venture out into the desert for a hike. Unfortunately, not everyone understands this.  So is it time to follow the lead of other insane warning labels and put a sign up warning would-be hikers not to venture off onto a trail when it is 110 degrees?

Sure seems like it.
