Prague in summer: tips and things to do
What to do in June, July and August: beer gardens, the river and 16-hour days
Tareq Maanan
Founder and guide at ODISEA. I came to Prague more than 10 years ago and never left. Over 5,000 tours later, the city still surprises me. I write these articles for the same reason I guide: so that nobody leaves Prague with the brochure version.
April 9, 2026 · 10 min readPrague in summer is spectacular. Days stretch beyond 16 hours, beer gardens stay packed until eleven at night, there are concerts in parks, the River Vltava becomes the social heart of the city and the energy on the streets is unlike any other season. But there is also heat, travellers everywhere, and a few avoidable mistakes that can ruin the experience.
At ODISEA we have been guiding in Prague in Spanish since 2017, summer after summer. We have seen quiet summers and summers when a man poured a bottle of water over himself in the middle of a tour to cool down. This article is what we would tell a friend coming in June, July or August: what to expect, what to do and how not to suffer in the heat.
The weather in summer: what to actually expect
Summer in Prague is not the Mediterranean. It is a continental heat: dry in the morning, muggy in the afternoon, with thunderstorms that appear out of nowhere and vanish within half an hour.
Average temperatures:
| Month | High | Low | Hours of sun/day | Rainy days |
|---|---|---|---|---|
| June | 22 °C | 11 °C | 7,4 h | 10 |
| July | 24 °C | 12,5 °C | 7,7 h | 9,5 |
| August | 24 °C | 12 °C | 7,2 h | 9 |
July and August have average highs of 24 °C, but heatwaves can push past 35 °C for several days running. Humidity sits around 69%, which makes the heat feel more intense than the thermometer suggests.
Summer thunderstorms
Summer thunderstorms in Prague are a regular occurrence. June and July are the rainiest months (about 70 mm each), but the rain comes in bursts: heavy downpours lasting 20-40 minutes, usually in the afternoon. Afterwards, the sky clears and the city smells fresh.
Practical tip: Always carry a lightweight rain jacket or a foldable umbrella. If a storm catches you, duck into any hospoda (Czech pub) and wait it out over a beer. It will be over in 30 minutes.
The air conditioning situation
This catches many travellers off guard: air conditioning is NOT standard in Prague. Many 3-star hotels, apartments and restaurants do not have A/C. Czech buildings are designed to retain heat in winter, not to cool down in summer.
Before booking accommodation, check explicitly that it has air conditioning if you are travelling in July or August. On Booking.com you can filter by this feature. It is the single most common complaint I hear from travellers arriving from warmer countries.
Things to do in Prague in summer
Summer transforms Prague. Everything that stays closed or empty during winter comes to life.
Beer gardens: Czech social life in the open air
Czechs live in beer gardens from May to September. These are not small bar terraces: they are enormous spaces, usually in elevated parks with city views, where people sit on wooden benches drinking cheap beer and eating sausages.
The essentials:
- Letná Beer Garden. In Letná Park, with the best views in Prague. A large beer costs around 80 CZK (~3.20 EUR). Wooden benches, no pretensions, panoramic views of the River Vltava and its bridges. This is where locals go after work.
- Riegrovy Sady. In Vinohrady, Prague's most pleasant neighbourhood. Big screen for football and sporting events in summer. Well-priced beer and a family-friendly atmosphere.
- Náplavka. The bank of the River Vltava turned into a social hub. Barges with bars, food trucks, live music at weekends. On Saturdays there is a farmers' market (8:00-14:00) with over 90 stalls. Beer from 75 CZK (~3 EUR).
The River Vltava: the centre of everything
In summer, the Vltava stops being just a pretty river in the background and becomes the axis of social life. You can hire pedal boats (~300 CZK/hour, ~12 EUR) at Slovanský ostrov, take a one-hour cruise (~18 EUR), or simply walk along Náplavka at sunset while people play guitar on the riverbank.
Concerts and festivals
Prague in summer has a cultural calendar that never stops:
- Concerts in palace gardens. Several historic gardens host classical music and jazz concerts outdoors throughout the summer.
- Concerts in parks and squares: many of them free. Check the city's cultural calendar for your travel dates.
16-hour days
This is one of Prague's great summer secrets: the days are extraordinarily long. On 21 June the sun rises at 4:50 and does not set until 21:15. That is more than 16 hours of natural daylight.
What does that mean in practice? You can have a relaxed breakfast, sightsee all morning, rest at a beer garden around midday, head out again in the afternoon and still have dinner in daylight. It feels completely different from visiting in winter, when it is already dark by 16:00.
June, July or August: which to choose?
This is the question we get asked most. The short answer: it depends on your priorities.
June: the perfect balance
- Pleasant temperatures (22 °C high), no extreme heatwaves
- Fewer travellers than July-August
- The longest days (summer solstice on 21 June)
- Hotel prices still reasonable
- Best for: those who want good weather without overcrowding
July: peak atmosphere
- Temperatures at their highest (24 °C average, peaks of 30-35 °C)
- Cultural programme in full swing
- Beer gardens busy but with a great vibe
- More travellers, but manageable
- Best for: those who want the city firing on all cylinders
August: the city at full capacity
- It is the peak of high season, with more visitors than any other month
- Hotels considerably more expensive than in spring
- Energy at its highest, but longer queues and more congestion
- Best for: those who do not mind sharing the city with the rest of the world
If you need a concrete plan, check our itinerary for what to do in Prague in 2 days. My recommendation: If you can choose, June gives you the best balance. If you can only make it in July or August, do not worry: Prague in summer is worth it in any of the three months. You just need to plan a little better.
If you are going specifically in August, read our guide to Prague in August.
Clothing and footwear: what nobody tells you
Footwear: trainers or sturdy sandals
This matters. Prague's city centre is covered in cobblestones. These are not flat, pretty cobblestones: they are uneven, slippery when wet and punish any thin sole.
- YES: Comfortable trainers, sport sandals with good soles (Teva-style or similar)
- NO: Flip-flops, heels, unsupported ballet flats
Flip-flops are the number one mistake we see among travellers in summer. They work for the beach, not for walking 15,000 steps on cobblestones. After two hours your feet will ache and you will probably have slipped at least once.
Clothing
- Lightweight, breathable clothing during the day
- A thin layer (light hoodie or long-sleeved shirt) for the evening: temperatures drop to 11-13 °C after sunset
- Rain jacket or foldable umbrella always in your bag
- Hat or cap for the midday hours if you are sensitive to the sun
- Sun cream: it may not seem like it, but Prague sits at the same latitude as Frankfurt and the summer sun is strong

What changes in summer
- Larger groups. Summer is peak season. Groups grow and the most popular tours can fill up. Book several days in advance, especially for weekends.
- Hydration. Bring a water bottle. Seriously. On a 2h30 tour at 30 degrees, staying hydrated is the difference between enjoying it and enduring it.
- Shade. We adjust the pace and, when the heat is extreme, we prioritise stops with shade and water points.
- Adapted route. We can adjust the route based on the weather, events or circumstances of the day. The priority is that you enjoy yourself, not that you suffer.
A summer anecdote
One summer, during a tour, a man simply poured an entire bottle of water over himself to cool down. Everyone laughed, and he had a point: sometimes the heat really is that intense. But that is part of the experience. Prague in summer is intense, alive and full of energy. You just need to come prepared.

Summer day trips from Prague
Summer is the best time for day trips, because castles and towns operate on extended hours.
- Karlštejn: about 40 minutes from Prague. In summer it is open every day with full hours. A spectacular Gothic castle in the middle of the forest, perfect for escaping the city heat.
- Český Krumlov: the most photogenic town in Czechia, at its best in summer.
- Kutná Hora: the Sedlec Ossuary and St Barbara's Cathedral, with longer opening hours in summer.
All the day trips are in our guide on what to see near Prague. And if you are still choosing dates, find out the best time to visit Prague.
Where to eat and drink in summer
Czech food is hearty: stews, roast pork, dumplings. In summer, that can be too heavy for lunch.
Summer alternative: Use the beer gardens for something light (sausages, bread and cheese) and save the heavier dishes for dinner, when the temperature drops. Czechs do not eat svíčková at 14:00 in August, and neither should you.
The Náplavka markets (Saturdays) are perfect for a casual lunch: local produce, quality street food and craft beer by the river.
Check our guide to traditional Czech food to know which dishes to try.
Frequently asked questions: Prague in summer
Does it get very hot in Prague in summer?
The average is 22-24 °C, but heatwaves can push past 35 °C. It is not constant heat like southern Spain; it is more unpredictable. One day you are at 32 °C and the next at 20 °C after a storm. The tricky part is the lack of air conditioning in many places, not the temperature itself.
Does it rain a lot in summer?
June and July have the highest rainfall (about 70 mm), but it comes in the form of short, intense storms. These are not full days of rain. Carry a rain jacket and you will be fine.
Is Prague expensive in summer?
More expensive than in the low season, yes. Hotels cost considerably more than in spring. But Prague remains significantly cheaper than London, Paris or Rome: a large beer costs 2-3 EUR and a daily menu at a hospoda runs at about 8-9 EUR.
Is Prague worth visiting in summer with children?
Yes. The parks, the river, the beer gardens (they are family-friendly, not just for adults), the pedal boats and the long days make summer a good time for families. The only extra care needed is keeping everyone hydrated and avoiding the midday hours outdoors.
Do the free tours run in extreme heat?
Yes. Our tours run every day, in any weather. On extremely hot days, we adjust the pace, prioritise shade and recommend bringing water and sun protection. In summer, our advice is to choose a morning tour, when it is cooler.
Prague in summer is a different city: loud, alive, full of people and with days that never seem to end. It is intense, but it is spectacular. All you need is comfortable shoes, a bottle of water and a willingness to walk.
