I would venture to say it's the same temperature as the outside, and can vary. Sometimes cooler and sometimes a little hotter. Never bothered me. The Auditorium is worth the visit. Nothing like it!
Better than outside temp, you are un shad and you usually get the ocean breeze so that helps.
During an event they usually open all windows and doors which let's in a breeze to cool everything down. This would be weather permitting.
