Andalusia holds Granada's Alhambra fortress walls and Generalife gardens, Córdoba's Mezquita with its 850 columns, and Seville's flamenco peñas in Triana with the Sierra Nevada rising behind.
Holy Week processions through April pack Seville, Málaga, and Granada, Feria de Abril two weeks after Easter, and Patios de Córdoba festival in early May.
Hits 42°C in Seville and Córdoba and outdoor walking punishing, but Sierra Nevada stays 15°C cooler and the Costa del Sol beaches at peak.
Olive harvest in Jaén, Bienal de Flamenco in Seville every even September, and the Alhambra gardens at peak photogenic without summer crowds.
Mild winter around 14°C, Sierra Nevada ski runs December-April above Granada, and tapas bar culture indoors at peak in Triana.
