Under a roof
The next stop in a storm needs a roof, and it stays in the district. In the old town: Museum Siam (closed Monday) or Wat Pho's galleries if they are still open. In Siam: Paragon or the art centre. At Asok: Terminal 21. Leave Wat Arun's prang, Benjakitti's exposed walk and Chatuchak's open lanes when the rain arrives. After it stops, decide whether to return to the same axis. Do not use the rain as the moment you transfer to Thonglor.
