We were there. During our recent rip to Copenhagen, we were caught in the most amazing deluge I have ever seen. After an amazing trip to the art gallery at Louisiana, where the weather was like this:
We returned to Copenhagen in late afternoon. Arriving at Norreport Station, we stepped off the train and into a storm of biblical proportions. Hiding in the station, we watched as traffic ground to a halt and the skies darkened as though night had come. It rained so hard, for almost two hours, that the station roof started leaking and it rained inside too. I read on Copenhagenize that there were 5,000 lightning strikes those two hours. It felt as though the paparazzi were lurking outside, flashbulbs popping.
Of course, the rain did eventually stop. We were able to return our hire bikes in time (through deserted streets) but the ensuing traffic chaos resulting from the flooding caused us no end of problems - trains were delayed, buses diverted and traffic jams appeared everywhere. How we wished we'd hung on to the hire bikes, as the Copenhagen citizen cyclists kept on rolling.
