Why is spectacular meteor shower viewing a highly localized affair?

Answer

Viewing success depends on local geography and atmospheric conditions.

The visibility of a meteor shower is highly localized because it is governed by several factors unique to the observer's position on Earth. The primary elements influencing success include the observer's geographical location, the local time relative to the radiant's position, and the presence of atmospheric obstacles or light sources. It is a common misconception that global activity translates to uniform viewing; in reality, obstructions and atmospheric conditions dictate whether one sees a spectacular show or very little activity, irrespective of how intense the event might be elsewhere. For example, geographical latitude determines the height of the radiant, and localized issues like light pollution or the presence of the Moon can severely dampen the visual experience for one person while another nearby enjoys a great view.
