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.

Weather and Temperatures

If you want to enjoy Prague with nice temperatures, perfectly suited to long walks through the Old Town, June might be the best choice. The average temperatures are 16°C (61°F), created by highs of 20°C (68°F) during the daytime and lows of 10°C (50°F) after dark. This rises to 17°C (63°F) by the end of the month, created by highs of 22°C (72°F) during the daytime and lows of 12°C (54°F) after dark.

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.

July is usually the warmest month in Prague. At this time of the year, the average temperature for the city starts off at 17°C (63°F), created by highs of 22°C (72°F) during the daytime and lows of 12°C (54°F) after dark. But it is quite often much warmer. For example in 2015 the temperatures were record-breaking, with 11 consecutive days of tropical nights (temperatures exceeding 30°C / 86°F). The highest temperature measured in Prague that month was 37°C (99°F), heat wildly unusual in the Czech Republic’s mild climate.

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).

During August, the average temperature in Prague begins at 21°C (69°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.

There are many open-air festivals and music events taking place in summer, especially at the end of August, when the school holidays are coming to an end. You can ask the concierge in your hotel what outside events are taking place during the time of your stay, and choose according to your taste.

And lastly, some information especially for men who can appreciate female beauty: it is true what is said about Czech women. They really belong among the most beautiful in the world. And when Prague flares with summer sun, you can admire many beautiful women, dressed for some holiday fun.
