Analysing the evolution of the number of occurrences and of the burnt area since 1995, a decrease in the number of occurrences (hot flushes and rural fires) since 2006 is noticeable, when compared to previous years.
The national database of rural fires registered, for 2018, a total of 12,262 rural fires that resulted in 44,520 hectares of burnt area, between stands (21,868 hectares), brushwood (19,437 hectares) and agriculture (3,215 hectares).
The year 2018 was the 2nd lowest value in the number of fires and the 3rd lowest value regarding burnt area since 2008.
The daily severity index (DSR) is an indicator of the severity of weather conditions. The annual cumulative analysis of this index since 2008 shows that the meteorological severity in 2018 was the second least severe and followed a pattern similar to the year 2008.
