Recent evolution of spatial and temporal patterns of burnt areas and fire weather risk in the Iberian Peninsula

•Iberian pyro-regions were identified with normalized burnt area (NBA) clustering for different periods.•Recent changes in pyro-regions borders were caused by changes in seasonal NBA patterns.•Changes in NBA patterns/pyro-regions can be explained with extreme fire weather patterns.•DSR and DC are the most relevant drivers amongst the fire weather indices.•A very strong link between DSR and extreme fires was found in the NW pyro-region.
