According to the IPMA, the hot weather being experienced now across the country “is due to the influence of a hot and dry air mass originating in North Africa, resulting from an anticyclone located over the Bay of Biscay and a depression centered in the south of the Iberian Peninsula”.
"This atmospheric pattern has also favoured the transport of dust over the mainland, which is expected to continue to affect the country until, at least, the end of this week".
