Electrical discharges cause great damage to people and the economy. The adaptation measures lead to the analysis of the phenomenon, its spatial distribution and its variability over time, keeping the studies updated. The objective of the present work is to analyze the interannual course of the occurrence of storms in the period where all the stations of the country have complete and unbiased information for the present and past weather state code variables. For the study, records of present and past weather conditions are used for 68 stations in the country in the period 2005-2019, where the information is complete and allows the number of days with storms per year to be calculated. The analysis of the interannual changes in the number of days with storms shows that in 35% of the stations under study there is an indication of the decreasing nature of storm activity. Of the stations under study, only four show a growing trend and 21 are homogeneous. The analyzed series show a decreasing behavior from the year 2015 in almost all the stations under study.
