What needs doing to an Algarve house, and when?

Almost half the Algarve's rain falls in October, November and December: 221.5 mm of a 455.1 mm annual normal at Faro, on IPMA's 1991 to 2020 figures. That one number sets the whole calendar. Anything that has to keep water out is finished by the end of September, anything that needs dry weather is done between May and August, and the pine processionary and mosquito seasons run on their own clocks. The month by month list below is dated 2026 and every figure in it carries its source.
