Beer gardens on the hills, the river islands in use, open-air stages and screens, and light that lasts until nine. Everything the city does between the first warm week of June and the end of August.
Summer is when Prague moves outdoors and stays there. The beer gardens on Letná and in Riegrovy sady run until late, the islands and riverbanks fill with people who live here, open-air cinemas appear in courtyards, and the free concerts start in the baroque gardens. Nothing about the city is hidden in summer — which is exactly the problem in the middle of July.
The trick is knowing where locals go when the centre is full: the swimming spots on the edge of the city, the parks nobody photographs, the trails an hour away by train. This page has the month-by-month picture, the season’s fixed dates, and the places worth the tram ride.
Summer, month by month
June is the one to aim for: everything is open, the light is at its longest and the crowds have not peaked. July and August are hotter, fuller and cheaper in a different way — the locals leave.

September is technically autumn and, most years, the better month: same warmth, half the queue. See Jesień w Pradze.
The rhythm of the season
Summer runs on seasons rather than single dates — gardens, screens and stages that open for months at a time. The two fixed public holidays and the big August festivals are below; exact dates are confirmed each spring in the linked guides.
Beer gardens, terraces and parks
Beer, properly
Parks and green
Swimming, the river and the islands
The river
Festivals, stages and late evenings
The concert halls close for the summer and everything moves outside: gardens, courtyards, islands and the parks. A good share of it is free.
More music
Out of the city
Everything is open in summer, which makes it the one season where the whole country is available. Trains are cheap, and the hiking network is one of the best signposted in Europe.
Eating outside
Czech cooking is heavy for thirty degrees, and the summer version of it knows that: grilled meat, cold beer, fruit dumplings and whatever is in season at the farm stands.
Summer dishes
Summer with children
The easiest season for it: everything is outdoors, everything is open late, and there is water within a tram ride of anywhere.

Summer in Prague, answered
June, July or August?
June, if you can choose. The days are longest, everything is open and the crowds have not peaked. July is the hottest and busiest. August is a good compromise — Czechs are on holiday, the festivals are on, and the last week starts to feel like autumn.
How hot does it actually get?
A normal summer day is 23–26°C. Several times a summer it goes past 30°C, and the old buildings hold the heat. Air conditioning is far from universal in Prague hotels and apartments, so check the listing rather than assuming.
Where do people swim?
Not in the Vltava in the centre. Locals use the reservoirs and lakes outside the city, the outdoor pools, and the natural pool at Divoká Šárka. Swimming spots around Prague has the full set with transport notes.
Is the centre unbearable in July?
Between about 10:00 and 18:00 on Charles Bridge and Old Town Square, close to it. The city is still very manageable if you shift your day: sights early, park or river in the afternoon, centre again after eight when the day-trippers have gone.
What are the July public holidays?
5 and 6 July — Cyril and Methodius Day and Jan Hus Day. Shops and offices close, museums and sights generally open, and the city is noticeably quieter. See the public holidays guide.
Is anything closed in August?
Some smaller restaurants and pubs close for two or three weeks while their owners take holiday, and the main concert halls are between seasons. Everything a visitor is likely to want is open; a specific pub you read about might not be.
What is a beer garden, exactly?
An outdoor bar in a park with trestle tables and a serving hatch: you queue, pay cash or card at the counter, and carry it to a table yourself. No reservations, no service, and it closes when the weather does. The guide covers the etiquette.
