King Abdullah Financial District in April

October through April offers the only bearable weather for exploring KAFD on foot. December and January are perfect — sunny days around 22°C and cool evenings that actually require a light jacket. February brings occasional rain that turns the district's fountains into impromptu waterfalls. March and April heat up but remain pleasant until noon. Look, summer here is brutal. May through September sees temperatures above 40°C daily, and the concrete towers create a heat island effect that makes it even worse. If you must visit during summer, plan everything for early morning or late evening. The good news? Indoor spaces are aggressively air-conditioned, and most attractions connect via covered walkways or underground passages.
