Seasonal Weather Patterns and Cave Access

The weather in the Moravian Karst varies significantly throughout the year. However, the temperature inside the caves remains a constant 8°C (46°F). This makes the caves a cool escape during hot summer days. It also makes them feel relatively warm during the freezing Czech winters.

Spring is a vibrant time when the forests turn bright green. This is also when water levels are highest. High water can sometimes affect the boat tours in the Punkva Caves. Always check local updates if you plan to see the underground river during April or May.

Most caves are open from April to October. During the winter months, only the Punkva Caves typically remain open for visitors. The table below summarizes what to expect during each season in the karst region.

Crowds and Booking Your Visit from Brno

July and August are the busiest months for tourism in the Czech Republic. During this time, the Macocha Abyss boat ride can sell out weeks in advance. If you visit in summer, you must book your tickets early to avoid disappointment. Weekends are particularly crowded with local day-trippers from nearby cities.

Visiting during the shoulder seasons of May or September is highly recommended. The crowds are thinner, and the trails are much quieter. You will find it easier to secure tour spots even with less notice. This allows for a more spontaneous trip from your base in Brno.

For those who prefer solitude, winter is an excellent choice. While only one cave is open, the landscape is often covered in snow. The lack of tourists creates a peaceful and mystical atmosphere. You can find more details on how to get to Punkva Caves during the off-season via public transport.

What to Pack for the Moravian Karst

Regardless of the season, you must bring a warm jacket for the cave tours. The constant 8°C temperature feels very cold after spending time in the sun. Even in the height of summer, a fleece or light down jacket is essential. Long trousers are also better than shorts for the damp underground environment.

Footwear is another critical consideration for your trip. The paths inside the caves can be slippery due to high humidity. Sturdy walking shoes or hiking boots with good grip are necessary. If you plan to hike between the cave entrances, ensure your shoes are broken in for forest trails.

In spring and autumn, pack a waterproof shell or a compact umbrella. The weather in the Moravian hills can change quickly.
