density map 2006-2016

The average yearly number of cloud-to-ground lightning strokes per square kilometer from 2006 to 2019 ranged generally between 10 and 20 over the Hong Kong Territory.


Points to Note:

  • The above map shows the average lightning density in number of lightning strokes per square kilometer calculated from data obtained by the Observatory's Lightning Location Network. In preparing the map, some interpolation and smoothing of data have been carried out.

  • The number of lightning strokes and areas affected by lightning may vary from year to year. As the map is based only on data from the past few years, it does not represent the future trend.
