The ideal times to visit Portugal are during spring (April to June) and autumn (September to October), when the weather is mild and pleasant, perfect for outdoor activities and sightseeing. Spring offers blooming landscapes and fewer tourists for a more relaxed exploration, while autumn features vibrant colours, grape harvests, and culinary festivals. These seasons provide a respite from the intense heat and crowdedness of the peak summer months (July to August) — ideal for strolling through historic cities like Lisbon and Porto, relaxing on the beaches of the Algarve, or enjoying the scenic countryside.
