Nationwide, temperatures typically range between 14°C and 24°C (58°F–75°F). However, Spain's diverse geography means regional differences: Seville and the South are the warmest, with highs often reaching 28°C (82°F), making it feel like summer. In Madrid and the Center, the weather is mild and pleasant, perfect for terrace dining. Barcelona and the Mediterranean coast see highs around 23°C (73°F) with comfortable humidity. The North (Galicia and Basque Country) is cooler and can still be quite rainy, so a light jacket is necessary. With an average of 9 hours of sunshine per day and only about 6 days of light rain throughout the month, May provides the ideal climate for walking through historic cities and enjoying the blooming landscapes before the crowds peak in July.
