We were down in VA last year for Nationals and that's the longest stretch of time (4/5 days) in a row that we've had to play in extreme heat (around 100 with high humidity). Luckily, it was only 2 games a day max, and they had covered dugouts. But yeah, it was oppressive. It was close to the limit in my opinion, and I wouldn't have complained if they postponed games or shifted the schedule.
On the other end of the spectrum, we played a Halloween tournament a few years ago and had an 8am game. It was 27 degrees warm-ups.
