Sunrise and sunset shoots
It is not necessary to shoot these locations at sunrise or sunset but should you choose to do so then the Photographers Ephemeris is very helpful to determine the position of the sun. The website version is free and if you want to use it on your smartphone then you can download the App.
These locations are best shot in winter when the sun will rise and set over the sea. Once it rises over the land you will then need clouds to get reflected colour. For sunrises this will limit you from November to February.
