Flag:
The flag atop the main building must be changed every 18 days, and it is said to fly in the opposite direction of the wind.
temple architecture is made in such a way that the wind inside the premise flows in opposite direction of the wind flowing outside. an obstacle that is blunt, can make the wind have eddie vibrations within making the wind direction almost change 90 degrees near it.
due to the structure of the shikhars, there is indeed this effect which makes the wind bend and making eddies flow inside it. a biangular or triangular structure make wind actually flow almost opposite inside the obstacles like a reverse current.

Rath Yatra rainfall:
It is a tradition for it to rain in the Puri area on the day of the Rath Yatra festival, regardless of the month or season, a phenomenon that scientists cannot explain.
The Jagannth temple has four doors, and Singhadwaram is the main door of entrance to the temple. While you enter through Sindhadwaram, you can clearly hear the sound of waves, but once you passed the Singhadwaram, simply take a turn and walk back in the same direction, you will no longer hear the sound of waves. In fact, you will not hear the sound of waves as long as you are inside the temple.
