What is the dry season like in Portugal in 2026?

Northwest districts around Braga and Viana do Castelo keep a shorter summer dry window. Showers still appear more often than in the south, and landscapes stay greener: Living in Braga and Living in Viana do Castelo. Lisbon sits in a clearer wet-season and dry-season split. Alentejo around Évora and the Algarve around Faro and Lagos stretch the drought months furthest, with hot, dry summers that match the heat story in how hot Portugal gets in summer: Living in Évora, Living in Faro, and Living in Lagos.

Cool-season rain still returns, sometimes in intense bursts that matter for drainage even after a long dry spell. The durable pattern for movers is months of low rainfall and high outdoor water demand in the south, not a single national start date.

Expect higher outdoor water needs for gardens, terraces, and pools during southern dry months, and check whether your building or municipality posts temporary use rules when reservoirs and aquifers tighten. APA (Agência Portuguesa do Ambiente) frames drought and scarcity through monitoring and contingency plans; local notices can limit garden watering or non-essential outdoor use without inventing permanent national "dry season fees." Indoor drinking supply usually remains the priority.

Utility bills still track cooling, heating, and internet more than rainfall alone: Utilities in Portugal. People who love clear Algarve skies should still plan for dust, irrigation limits, and heat when choosing a villa with a lawn.
