Jeddah in May

April through June brings perfect weather — warm days around 28°C and cool evenings ideal for Corniche walks. September and October offer the same sweet spot after summer's furnace heat subsides. Winter months stay pleasant but can get surprisingly cool, especially for Red Sea swimming. Summer? Brutal. July and August hit 45°C regularly, turning sightseeing into an endurance test. But here's the upside: summer means fewer crowds and better hotel deals. The shoulder months of March and November work too, though March can still feel winter-cool for beach activities. Ramadan affects restaurant hours and cultural site access, so plan accordingly.
