Afternoon Game Sun

I usually end up sitting in the bullpen/mezzanine sections when I’m at the games. I know the sun gets BRUTAL over there during the late afternoon games, but was wondering how it is around 131-134? I assume it’s much of the same, but we very much prefer to sit near the first base line, so just looking for y’all’s personal experience there. Buying tickets for a 3:10 game and just trying to figure out where to sit so we’re not absolutely miserable in the sun. Thanks for any input!
