Is May Right for You?
Weigh the advantages and considerations before booking
Advantages
- + May brings the first reliably warm days after Brno's long winter, with outdoor cafés along Zelný trh finally filling up with locals drinking Gambrinus in the sun
- + The city's parks - Lužánky and Špilberk - explode with lilac and chestnut blooms, and the scent drifts down through the old town's narrow lanes
- + Hotel prices are still at shoulder-season rates before the summer rush, and you'll find availability even at the historic Grandezza Hotel on the main square
- + The wine season kicks off with open-cellar weekends in nearby Velké Pavlovice, where Moravian winemakers pour their first young wines straight from the barrel
Considerations
- − May weather is unpredictable - you might need a sweater at 9am, be sweating in a t-shirt by 2pm, then caught in a downpour at 4pm
- − The city's famous underground tours get damp and musty-smelling as spring rains seep into the medieval tunnels beneath Zelný trh
- − Outdoor beer gardens are open but evenings still drop to 9°C (49°F) - that riverside table at Pegas brewery sounds romantic until you're shivering in your summer dress
Best Activities in May
Top things to do during your visit
Brno in May sheds its spring chill for confident, leafy warmth. Mornings are cool enough for a jacket. The sun lingers until evening, coaxing linden trees into full canopy over the cobblestones. Outdoor life resumes. Terraces spill across pavements. The park beneath Špilberk Castle becomes a stage for sunbathers and chess players. Two events define the month. The convivial Moravian Wine Festival brings folk energy. The sophisticated Brno Jazz Festival offers smoky notes. Both draw crowds into the old squares and castle courtyards. Longer days invite exploration on foot. Start with wartime bunkers, then head to the surrounding hills. The scent of grilled sausage and young wine hangs over Zelný trh market square during the first weekend. It is a celebration of the Moravian harvest. Later, improvised jazz riffs echo from historic cellars. This sound contrasts with the quiet grandeur of the city's functionalist architecture. Visiting Brno in May means witnessing a city engaged in the rituals of spring.
Skip the Line: 10-Z Bunker Entrance Ticket in Brno
skip_lineDescend into the chilled silence of Brno's nuclear bunker, built deep within the Špilberk hillside. The air feels permanently damp and cool. It is a stark contrast to the warm May sun above. You will pass heavy blast doors and austere living quarters. They tell a story of Cold War tension. This is a haunting journey. The only sounds are echoing footsteps and the faint hum of ventilation.
It is a physical immersion into Czechoslovakia's Cold War preparations, far from the city's Baroque facades.
Insider tip: Wear sturdy shoes and a warm layer. The underground temperature stays constant and floors are uneven.
PUNKVA CAVES, ABYSS and PERNSTEJN CASTLE =only from Apr to Sep
otherJourney from Brno into the Moravian karst. First, gaze into the void of the Macocha Abyss, a vast limestone chasm. Mist often lingers there in the cool morning air. The adventure continues with a boat ride on the subterranean Punkva River. Your punt glides past stalactites and mirrored pools, all illuminated by lights. You will then emerge for a guided tour of the hilltop Pernstejn Castle.
This single day combines a geological wonder, a serene river voyage, and a preserved medieval fortress.
Insider tip: Book the earliest tour slot. You will avoid visitor groups at the caves and have the castle courtyards more to yourself.
This month: This combined tour operates only from April to September. May is ideal with reliable access and comfortable temperatures.
Brno Food Tasting Tour of Hidden Gems for Small Groups
foodThis tour moves beyond main squares to unmarked doorways and family-run cellars. Taste the smoky, paprika-spiced heat of traditional Moravian sausage. Sample tangy pickled cheeses from a market stall. Finish with a plum-based spirit in a tucked-away pub. You will hear stories of the vendors and their generations-old recipes.
It unlocks the authentic flavors and personal stories behind Brno's food scene, which casual visitors often miss.
Insider tip: Come with an empty stomach. Ask your guide about the origin of the city's symbolic crocodile, a tale often shared over a drink.
3 Hour Private Tour with a Local Guide in Brno
private_tourThis experience has a personalized key to the city. A resident guide tailors a walk to your interests. You might decode the symbolism on the Astronomical Clock. You could find the best viewpoint for the Cathedral of St. Peter and Paul. Or learn the legacy of architect Mies van der Rohe. You will learn how locals interact with these spaces daily.
A private guide provides context. It transforms Brno's landmarks from static sights into parts of a living narrative.
Insider tip: Discuss your interests in detail when booking. Your guide can then prepare and perhaps arrange a visit to a closed courtyard or a local cafe.
Half Day Tour to the Macocha Abyss and The Punkva Caves
guided_experienceFocus on the natural wonders of the Moravian Karst. This half-day tour goes directly to the impressive Macocha Abyss and the Punkva Caves. Feel the cool, mineral-rich air of the caverns. Hear the drip of water forming new stalagmites. You will walk and boat through illuminated chambers. Expert commentary brings the slow-motion geology to life.
It provides a concentrated, expert-led immersion into one of the region's most spectacular natural phenomena. Good for limited time.
Insider tip: The cave paths are well-maintained but can be slippery. Wear footwear with good grip. Avoid long coats or bags that might catch on rock formations.
Trip to the Austerlitz Battlefield near BRNO in the Czech Republic
otherTravel from Brno to the rolling fields of Slavkov. The silence today belies the thunder of cannons that once decided the fate of empires. Stand on the Pratecky Hill memorial. Feel the wind sweep across the grasslands. Your guide will recount the tactics and human drama of the Battle of Austerlitz. The strategic landscape becomes vividly clear.
It is a masterclass in military history, made immediate by standing on the ground where Napoleon achieved his greatest victory.
Insider tip: The battlefield is expansive and exposed. Even on a mild May day, bring a windbreaker and hat for the open plateau.

May Events & Festivals
What's happening during your visit
Early May
Moravian Wine Festival
The first weekend of May sees winemakers from across the region set up stalls in Zelný trh, pouring young wines that won't appear in restaurants for months. Locals queue for burčák - partially fermented grape juice that's cloudy, sweet, and surprisingly alcoholic. The square fills with folk music and the smell of grilled klobása until midnight.
Mid May
Brno Jazz Festival
Intimate venues across the old town host Czech and international jazz acts over two weekends in mid-May. The basement club at U Kocoura fills with cigarette smoke and saxophone echoes, while outdoor sets at Špilberk Castle happen in the late afternoon when the stone walls amplify the acoustics well.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The crocodile fountain on Zelný trh isn't just decoration - locals rub its nose for luck before exams, which explains why students line up during May's university finals period
May is when Brno's famous caf culture returns outdoors - grab a table at Café Podnebi by 10am to watch the morning market crowd. But bring a jacket for when clouds roll in
Wine cellars in the suburbs like Židenice stay open later than tourist spots - take tram 12 to Hlinky stop for authentic local atmosphere without tour groups
The vegetable market on Zelný trh peaks on Tuesday and Friday mornings - show up at 7am for the first strawberries and asparagus. But vendors pack up by 1pm regardless of weather
Avoid These Mistakes
Evening beer gardens tempt. But nights bite. Locals keep jackets on chair backs. Temperatures drop fast after sunset. Bring layers. Outdoor drinks stay possible. Just plan for the chill.
Book underground tours for morning slots. Spring rains flood lower passages by noon. Afternoon reroutes skip the best sections. Go early. See the full maze. Beat the rising water.
White shoes die here. Sandstone cobbles bleed brown when wet. The stains lock in forever. Pack dark soles. Brno rewards the practical. Mud wins every time.
Always queue an indoor backup. May flips skies hourly. Storms pack the Technical Museum fast. Have a Plan B. Crowds increase indoors. Beat them there.
