Weather & Best Time to Visit in Lisbon

Best time to visit Lisbon

Late spring (April-May) or early autumn (September-October). Warm and sunny with daytime highs of 68-79F, significantly fewer crowds than July-August, lower hotel rates, and green parks. September still warm enough for nearby beaches (avg high ~79F/26C) while summer crowds have thinned. April-May offers festivals and blooms. Both shoulder periods avoid peak-season queues at Alfama, Tram 28, and Belem
