The best time to go to Grassano is generally during the late spring (May to early June) and early autumn (September to early October) when the weather is pleasant for exploring.
During these months, you'll find the temperatures are comfortable, typically ranging from 20-25°C, making it ideal for walking around the historic centre or taking day trips to the surrounding countryside. The intense heat of the summer has usually passed, and the cooler, wetter weather of late autumn and winter hasn't yet arrived. This period also avoids the busiest tourist crowds, which tend to peak in July and August.
Couples looking for a relaxing holiday will appreciate the quieter atmosphere during these shoulder seasons, allowing for more intimate experiences at local restaurants and less crowded visits to attractions like the Museo Civico. The natural beauty of the Basilicata region, with its rolling hills and olive groves, is particularly appealing in the milder weather, great for leisurely drives.
Families travelling with children will also find these times more agreeable. The pleasant weather means outdoor activities are more comfortable, and exploring the town's historical sites is less strenuous without the summer heat.
