Nine municipalities in the Algarve have "maximum" rural fire danger, according to the Portuguese Institute of the Sea and the Atmosphere (IPMA). The affected municipalities are Monchique, Portimão, Silves, Loulé, São Brás de Alportel, Tavira, Alcoutim, Castro Marim and Vila Real de Santo António.
Other five Algarve municipalities have "very high" risk, namely Aljezur, Lagos, Vila do Bispo, Lagoa and Albufeira. Faro and Olhão are classified with "elevated" danger.
IPMA uses a five-level scale of rural fire danger, ranging from "reduced" to "maximum". The calculations to determine these levels are based on air temperature, relative humidity, wind speed and amount of precipitation recorded in the previous 24 hours.
