Amsterdam in March

April through September offers Amsterdam at its best. Tulip season peaks in April when Keukenhof Gardens bloom and King's Day (April 27) turns the entire city orange. May and June bring perfect cycling weather and longest daylight hours. July and August see peak crowds and prices, but also outdoor festivals and canal-side dining. September offers ideal temperatures with fewer tourists—locals call it the secret best month. October brings cozy brown cafe season but unpredictable weather. November through March means shorter days and frequent rain, though Christmas markets and lower hotel prices compensate. Museum visits work year-round, and indoor attractions like Heineken Experience stay busy regardless of weather. Book accommodations early for King's Day, Amsterdam Dance Event (October), and summer weekends.
