The best time to go to Katov depends on what you're hoping to experience, but generally, late spring (May-June) and early autumn (September-October) offer the most pleasant weather and fewer crowds.
May and June are wonderful for enjoying the countryside as it bursts into bloom. The temperatures are mild, typically ranging from 15°C to 25°C, making it ideal for outdoor activities like cycling, hiking, and exploring the local castles and chateaux without the intense summer heat. You'll find the gardens at nearby Písek Castle and Blatná Chateau particularly beautiful during this period.
Families often find the summer months of July and August appealing, despite being the busiest time. The weather is warmest, often exceeding 25°C, which is great for enjoying the numerous lakes and rivers for swimming or boating. Local festivals and outdoor events are also more frequent. However, expect more visitors at popular attractions and potentially higher accommodation prices.
For those seeking a quieter trip with beautiful scenery, September and October are excellent. The summer crowds have thinned, and the landscape transforms with autumn colours, creating a picturesque backdrop for walks and photography. Temperatures are still comfortable, usually between 10°C and 20°C, and there's a good chance of crisp, sunny days.
