Lightning density map for Hong Kong

density map 2006-2021
The average yearly number of cloud-to-ground lightning strokes per square kilometer from 2006 to 2021 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 lightning density shown on the map is based on past data only, it does not represent the future trend.
