Anytime one tries to get a nice reflection on any water in a middle of a city, going there early in the morning is always the best. It’s the only time when the water is nice and calm, with no ships running around. It was exactly the same in Dubai. The Dubai marina canal is not that heavily frequented by ships, but still enough to destroy the reflections.
