Best month
May
Porto's most balanced month — warm, mostly dry, NOS Primavera Sound approaching, and crowds not yet at summer levels.
↑Weather reaches its sweet spot: 21°C highs, 8 hours of sunshine daily, and only 55mm of rainfall — the Foz do Douro beach and the Douro riverfront are at their most enjoyable
↑NOS Primavera Sound (late May, Parque da Cidade) — one of Europe's finest music festivals brings international headliners to Porto's coastal park; a genuine reason to choose this month
↑The whole city is in outdoor mode: rooftop bars, the azulejo-tiled café terraces on Rua de Santa Catarina, the Jardim de Serralves gardens in full spring bloom
