The only issue is that San Diego has recently had these humid and warm days, which makes being outside in a stadium without a canopy or shade like Snapdragon a little uncomfortable...they had this exact same issue, more so just really damn hot, the first event last year at Snapdragon.
But 100% agree with you on Levi Stadium. Not only is it a furnace but not much to do around the immediate surrounding area. Most weekday Tour matches in America have been during the evening, so I'd say maybe 5pm local time.
