Shiraz in July

March through May is perfect—mild days, cool nights, and everything blooms at once. The gardens explode with color and the air smells incredible. Fall works too, especially October and November when the heat breaks but it's still warm enough for evening walks. Summer is brutal. We're talking 40°C+ (104°F+) with desert dryness that sucks moisture from your skin. Winter surprises people with actual cold—sometimes snow—but fewer crowds and crisp, clear days make up for bundling up. Just avoid Iranian New Year in March when everything shuts down and prices double.
