However, lightning occurs worldwide; it is difficult to carry out an overall study of lightning everywhere, but some countries where lightning hazards occur very much.

Therefore, studying the lighting hazard in Sri Lanka from 1958 to 2009 to identify the periods (months, years) and provinces most incidents occur, the curse for the hazard, and whether an incident occurred indoors, or outdoors is carried out. The study also aims to identify the possible correlation between Rainfall and lightning. According to data, the highest incidence occurs during April, May, October, and November, and most incidences occur while people stay outside.
