Face west (and check the season)
It sounds obvious, but the sun’s setting point moves along the horizon through the year. A map app with a sun-path overlay will show you exactly where it will set on your dates.
Look for a little height
Clifftops, rooftop terraces and dunes give you a wider horizon and a view over the water’s reflections.
Arrive early, stay late
Be there thirty minutes before sunset to get a good spot, and stay twenty minutes after — the deepest colours often appear once the sun has gone.
Clouds are your friend
A completely clear sky can be beautiful but simple. Scattered high clouds catch the light and turn the whole sky orange and pink.
