Prague Weather/Climate in Summer 2018: June, July & August

1. Introduction

Every year, Prague is full of tourists in the warmest months of the year. And it is no wonder. The amazing city, at the same time modern and rich in historical and cultural heritage, is especially beautiful when lit by the bright rays of the summer sun. In June, July, and August, Prague fulfills its nickname of “Golden City” even more than during the rest of the year.

Of course, it is no surprise that summer is – from the point of view of tourism – a strong season for Prague, even though early Autumn competes with the summer season quite bravely. The main reason so many tourists choose June, July, or August to come to Prague (apart from the fact that Summer is holiday season in general) is the weather. The Czech Republic’s capital has a lot to offer to its visitors throughout the year, but the most visitors come to enjoy sightseeing, and that is, of course, most comfortable in warm, sunny weather. Also, during the warm months many Prague restaurants and cafés offer outside seating, so you can enjoy your Czech specials, great beer, or other refreshments overlooking the city’s buzz or with a view of some of its amazing historical landmarks…

Nevertheless, over the last few years, it may seem like the Czech Republic is shifting from a mild climate to a tropical one. So if you are considering visiting Prague during the summer season, always look up the weather forecast and take into account what temperatures are comfortable for you. If you are deciding on the month for your trip to Prague, you might also find the following info useful: while a mere decade ago, the months of summer school holidays (July and August) used to be the warmest and sunniest, the notional “peak of summer” has been gradually coming sooner and sooner.

In recent years, it was not exceptional that the hottest and sunniest days of the year were during June, or even May (of course to a great frustration of the schoolchildren). August then often showed almost autumnal weather, with less sun and a drop in temperature, and summer came back for a while in September. The so-called “Indian Summer” is usually a really beautiful time of the year in the Czech Republic…

What to do in Prague in June? Walk Through the City

As we already suggested, June is probably the best month to visit Prague if you enjoy sight-seeing on foot. In Prague, unlike some other popular European cities, a great many historical buildings and other attractive sights are concentrated in the historic city center, within a comfortable walking distance of one another. One of the most frequently used walking tours, exploring the major sights and attractions of Prague, starts at Prague Castle, where one climbs up the Old Castle Stairs and then goes down the “New” Castle Stairs (even though they are unofficially called “new”, they are actually pretty ancient and offer a wonderful view of Prague just like the Old Castle Stairs). After descending these stairs, which echo long-gone eras, one can walk through Nerudova street (also called Royal Way or Kings Road). The charming street is named after Jan Neruda, the famous Czech writer, and journalist, who allegedly lived here in the 19th century. “Nerudovka”, as the locals call the street, will enchant you with its ancient burgher houses, now mostly transformed into charming hotels, restaurants, and small shops.

From Nerudova street, our suggested tour will take you through “Malostranské náměstí” Square, via the beautiful Church of St. Nicholas, to Charles Bridge. This eminently famous historic bridge (originally called “Stone Bridge”) crossing the Vltava river is the oldest and undoubtedly most beautiful bridge in the city. It was built between the 14th and 15th century and its current name refers to the celebrated King of Bohemia and Holy Roman Emperor Charles IV. The bridge, spanning the Vltava river with 16 pillars, is rich in statues and decorative lamps, and with its beautiful Gothic bridge towers on both ends, the Charles Bridge is indeed a breathtaking historical monument.

After we cross Charles Bridge, we go on exploring the cobbled streets around the Old Town Square, with its wondrous Astronomical Clock, and stroll into the Jewish Quarter (Josefov), that used to be the largest Jewish ghetto in Europe. There, you can – among other things – explore the famous Spanish Synagogue and Old-New Synagogue or visit the Jewish Ceremonial Hall and the Old Jewish Cemetery, which is the most remarkable of its kind in Europe.

Undertaking our described sightseeing tour will enable you to see a really great part of the best historical sights Prague has to offer, and you will only walk approximately 1,2 km. You could easily walk this distance in 20 minutes, but trust us, you will have so much to admire that a whole day will pass seemingly in the blink of an eye…

What to do in Prague in July? Sail on a Boat

When Prague is sun-drenched, the air is warm, and the pavements hot, it is, of course, recommended to spend the day by the river. Or even better, on it. You can go for one of the many river cruises offered, where you sail on a bigger boat with a sightseeing tour guide, who will provide you with info on the sights visible from the Vltava river (such as of course Prague Castle, Vyšehrad castle, the National Theatre or Charles bridge).

There are also many party boats available, with music and a rich array of beverages and dishes, allowing you to admire the river banks of Vltava while dancing. And last but not least, you can go really romantic and rent a rowboat or pedal boat. Rowing and then just resting on the Vltava river on a sunny summer’s day, with Prague Castle or Charles Bridge in the background, is an amazing and unforgettable experience.

You can buy a ticket for a river cruise at “Dvořákovo nábřeží” (embankment), next to “Štefánikův most” bridge (“Nemocnice Na Františku” tram stop). Prices range from 200 CZK (8 EUR) to 2000 CZK (75 EUR), depending on factors such as the duration of the cruise and services (such as snacks) included.

If you choose to combine sailing on the Vltava river with experiencing Prague’s legendary nightlife, you can board a party ship. They anchor for example at “Náplavka”, a recently renovated riverbank in the center of the city (Rašínovo nábřeží, “Výtoň” tram station). The prices vary quite a lot; it is advisable to have a specific party boat recommended by a local. You can, of course, ask for advice in your hotel.

If you choose to rent a paddle boat, go to the island Žofín near the National Theatre or Novotného lávka near Charles Bridge. The rentals are usually open until 10 p. m., so you can also enjoy night time views of Prague. It will not cost you more than 250 CZK (6 EUR) per hour.

7. Prague Weather and Temperatures in August 2018

During August, the average temperature in Prague begins at 18.5°C (65°C), created by highs of 24°C (75°C) during the daytime and lows of 13°C (55°C) after dark. This gradually drops down to an average of 17.5°C (64°C) by the middle of the month, created by highs of 23°C (73°C) during the daytime and lows of 12°C (54°C) after dark, before reaching a low of 16°C (61°C) by the end of the month, created by highs of 21°C (70°C) during the daytime and lows of 11°C (52°C) after dark.

Nevertheless, in recent years August was several times colder than the mentioned averages, often with quite a lot of rainfall. So when you are planning your trip to Prague, it advisable to check the weather forecast.

Major Prague Events in August – Prague Pride Parade and Open Air Festivals

Apart from sightseeing, enjoying Czech cuisine with great beer or sailing on the Vltava river, there is plenty more to do in Prague during August.

The event is organized by the Prague Pride civic association, which aims to promote a tolerant civil society. They fight against homophobia and make an effort to increase public awareness of gay, lesbian, bisexual, and transgender communities in the Czech Republic. The main activity of the association, founded in 2010, has been to organize an LGBT human rights festival – Prague Pride.
