Phuket: Andaman Sunset From Promthep Cape and the Limestone Horizon

Golden hour, blue hour, and twilight times in Phuket. NASA JPL DE441 astronomical data.

Photo tip

Promthep Cape viewpoint at sunset: face south-southwest for the Andaman Sea horizon with the limestone karst islands as mid-distance silhouettes. Arrive 50 minutes early — the viewpoint fills completely in peak season (December–February) and upper terrace position is critical for the horizontal composition.

Phuket sits at 7.9°N on the west coast of the Thai peninsula, facing the Andaman Sea to the west. Golden hour lasts around 21 minutes. The west coast beaches (Kata Noi, Kata, Karon, Patong) face west-northwest and receive the full Andaman sunset arc over open water. Promthep Cape (the southern tip of the island, 40 m above sea level) provides the classic elevated position: the view south-southwest covers the open Andaman Sea, the limestone karst islands (Koh Bon, Koh Kaeo Noi) in the distance, and the sunset sky in the shooting direction. The Windmill Viewpoint (1.5 km north, 100 m elevation) offers a broader panoramic north along the Andaman coast. The dry season (November–April) produces clean skies; the wet season (May–October) provides dramatic cloud formations that are often more spectacular at some cost to reliability.
