Spring (April-May): Orchards bloom and the countryside turns green, with mild temperatures (10-18°C). Easter is a major event, with painted-egg traditions on full display. Fewer tourists than summer, though some mountain trails remain snow-covered into May.
Summer (June-August): Peak season - warm weather (20-28°C), all monasteries and museums fully open, and the best window for hiking Rarău and Călimani. Craft festivals and village fairs run throughout summer. Book accommodation in Gura Humorului and Vatra Dornei ahead for July-August weekends.
Autumn (September-October): Arguably the best time to visit - comfortable temperatures (12-22°C), golden forest color in the Carpathian foothills, and noticeably thinner crowds at the monasteries. Harvest and mushroom-picking traditions are visible in villages.
Winter (November-March): Snow blankets the monastery courtyards for striking photos, and Vatra Dornei/Câmpulung Moldovenesc become small ski destinations. Some rural roads and mountain trails become impassable; distances between sights take longer. Temperatures often fall below freezing (-10 to 2°C).
