Seville

Spring (Mar–May): Ideal weather—mild, sunny days around 18–25°C. Peak season because of Semana Santa (Holy Week) and the Feria de Abril; book ahead for hotels and tapas bars. Summer (Jun–Aug): Very hot, often 35–40°C or more, almost no rain. Tourist numbers remain high in July–Aug but many locals take siesta or leave the city; avoid August if you dislike extreme heat. Autumn (Sept–Nov): Warm to pleasantly cool (20→12°C), a calm shoulder season with fewer crowds and better rates. Occasional cultural festivals and the biennial flamenco Bienal fall here some years. Winter (Dec–Feb): Mild but cooler and rainier (10–16°C). Off-peak with lower prices and quieter streets; Christmas markets and Epiphany celebrations add seasonal charm.
