The sun never completely sets and moves horizontally across the horizon throughout the night. Europe's second largest island sees no night from early May till July because the sun is above the horizon all the time.
That's different in India. The sun sets around a time between six and seven. To create a thriving landscape, which consists and depends not only on great light but as well a strong composition. You can't control the former, but the latter is entirely down to you.
Most of the coastal landscape you shoot will be taken with a wide angle lens so that you can get more. However, what you choose to include has to be interesting to look at – if it isn’t, the resulting image will be dull. End of story.
