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
Moravian Wine Cellar Tours
May marks the start of wine season when family-run cellars in Velké Pavlovice and Mikulov open their doors for weekend tastings. The 40-minute train ride through rolling hills puts you in wine country where temperatures run 3-4°C warmer than Brno, good for sampling young Muller-Thurgau straight from stainless steel tanks in cool stone cellars that stay 12°C year-round.
Booking Tip: Book cellar visits 1-2 weeks ahead through the booking widget below - many smaller producers require reservations and don't accept walk-ins. Look for tours that include transport from Brno main station.
Špilberk Castle Panoramic Walking Tours
The castle hill hits its spring stride in May - chestnut trees bloom along the switchback paths, and morning temperatures around 15°C make the 15-minute climb from the old town comfortable. The reward is 360-degree views across Brno's red-tiled rooftops to the distant Alps, with visibility clear from recent rains and none of summer's haze.
Booking Tip: Morning tours starting 9am catch the best light and avoid afternoon thunderstorms. Licensed guides typically meet at the castle gate - see current options in booking section below.
Underground Labyrinth Exploration Tours
Brno's 10-kilometer tunnel network stays a constant 8°C year-round, making these tours good for May's variable weather. The medieval passages beneath Zelný trh include alchemist workshops, wine storage cellars, and WWII air raid shelters - the damp limestone walls smell more atmospheric after spring rains.
Booking Tip: Tours run hourly but book morning slots - afternoon thunderstorms can flood lower passages. English tours are limited to 15 people and fill up on weekends.
Villa Tugendhat Modernist Architecture Tours
Mies van der Rohe's 1930 masterpiece shines in May when the onyx wall panels catch the lower-angled spring sunlight that the house was specifically designed for. Morning tours at 10am show the famous living room glowing amber as light filters through the semi-precious stone - an effect that disappears in summer's high sun.
Booking Tip: Reserve at least one week ahead for English tours - only four run daily and May's architecture students book months ahead for thesis research. Photography without flash is permitted.
Brno Reservoir Cycling Routes
The 40-kilometer bike path around Brno Reservoir hits perfect conditions in May - temperatures hover around 18°C, wildflowers bloom along the shoreline, and the water sports crowd hasn't arrived yet. The route passes through the old quarry at Hády with its dramatic limestone cliffs, then follows the Svratka River back through forested sections that smell of pine and fresh rain.
Booking Tip: Rent bikes at the main station and take the train to the reservoir - the 12-minute ride saves you 8 km of city cycling. Return by 4pm to avoid afternoon storms.

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.
