The match started at 21:10 local time (20:10 BST).
Earlier in the day, UEFA warned match goers of possible thunderstorms in the Bavarian capital forecast for kick-off time.
Around an hour before the originally scheduled kick-off time, a storm swept across northern Munich, lashing the stadium with rain and leaving the arena grass carpeted in hailstones.
Goalkepeers from both sides had begun their warm-up when the storm hit.
