True darkness is generally hard to find in the city. Our street lights go on as the sun goes down, even our jetties have lights on them.
A lot of people shoot long exposure beachscapes when the sun goes down, which is what I tend to do also. Sometimes (rarely as I'm not a morning person - lol), I like to go out in the morning before sunrise. This is when you can get some really interesting shots with the tide being different to night time and the moon might still be up casting a glow on the water. I do have a few moon shots at sunrise but I haven't processed them yet, all in the archives still :)). Pre-sunrise mornings also generally mean an absence of people on the jetty, particularly in winter. Although plenty are still walking along the ocean front at first light.
