In Malaga we have some very beautiful sunsets. My wife usually calls me to our balcony of our apartment when she sees a specially beautiful sunset.
For a visitor to see these sunsets, one must go to a high viewpoint. One viewpoint is the rooftop terrace of the Hotel Malaga Palacio, which has views of the sea and the hills behind Malaga. From my experience a cloudy day is good because it becomes a backdrop with beautiful colors. And the good thing is one can enjoy these sunsets for free!
Sometimes you can see a cruise ship leaving or coming to port, with all its lights on. This is a beautiful sight.
That is an advantage one has when one lives near the sea.
