Summer is a great time to come and visit Prague, since it’s the warmest time of the year and you have the most daylight too. You can pack light and spend long days exploring the historic town centre, sitting in the shade of park trees having a picnic or enjoying a balmy evening in the outdoor theatre.
Whilst the general weather is similar in summer in the whole Czech Republic, Prague tend to get much warmer in the summer because the tall townhouses absorb the heat. There is also not a lot of wind and the town can be quite dusty.
When it’s very hot during the weekends (or holidays), most Prague people escape to their country cottages or at least leave the town for a day trip to a river, lake or cooling woodland.
PRACTICAL TIPS & WHAT TO SEE IN PRAGUE EACH MONTH DURING SUMMER
What is the weather like in Summer in Prague ?
Generally speaking, it can be very hot, with many heatwaves and also summer storms and even local flooding (this is usually much worse in Moravia and South Bohemia than in Prague).
When the weather is calm, it’s usually hot during day and it can rain in the night. This makes the next day slightly cooler in the morning, but it usually warms up pretty quickly.
Summer is the time when it’s the least rain and wind in the Prague and the most sunny days with full sun.
The night temperatures are also the warmest in the summer and usually don’t drop below 10-15 C. (During a heatwave this can be as high as 20 C). This is perfect if you are planning to do any camping trip or stay in country wood cabins for few days and explore the countryside outside Prague.

What are the temperatures like in summer in Prague ?
Most days in July can be very hot (up to 25-30 C in the shade, but much hotter in the sun),
When the sun is shining it can be very hot in the direct sun (easily up to 40 Celsius), so try to stay in the shade if you can. If you get easily sun burned, I’d recommend planning your day, so that you do some indoor activity between 1-3 pm. This is the time when the sun is at its hottest.
How does the weather change during summer in Prague?
Generally speaking, the weather is getting hotter and hotter as you progress through the June into July and then getting slightly colder as you get into the middle to end of August.
It’s still very warm throughout, but the temperatures in August are usually more bearable than in July.
What does the hot weather feel like in the summer?
If you are visiting from the UK you are probably used to seeing weather forecasts mentioning something like: temperature 20 C feels like 18 C or 22 C etc. This is because the same temperature can feel ‘hotter’ or ‘colder’ depending on the humidity of the air.
This might sound a bit difficult to understand, until you come to Prague and the weather forecast is something like 25C (which is often 30-35 C in the sun) and you are like ‘this is O.K, I can bear that!’ If this was in the UK you’d really struggle!
This is because in the Prague (and the Czech Republic – being a land locked country) the humidity is much lower than in UK and the heat feels ‘drier’ and because of that, it’s more bearable!
Saying that, the sun still has the same damaging effect to your skin, so make sure that you use sun block cream, hat, sunglasses or long loose clothing to protect yourself against the strong sun beams.
Is Prague too hot in the summer to travel?
Prague can get hot in the summer, but it is generally not too hot to travel. The temperatures are typically in the mid 70s Fahrenheit (around 24°C) during the day and can drop to the low 50s Fahrenheit (around 10°C) at night. While some afternoons can reach up to near 31°C (88°F) in the shade, it is usually not unbearable and there are ways to stay cool such as visiting Prague gardens and green parks or cooling off in the Vltava river.
If you are sensitive to heat or sunlight, it’s best to visit attractions in the morning and afternoon or evening and choose to stay somewhere in a shade during the hottest part of the day between 12- 3 pm. A museum visit is usually a good idea as these are in old large buildings and much cooler than being outdoors on the sun. You can also stay in the shade of the trees at beautiful Kampa Island as it’s a little cooler by the Vltava river. It is also important to stay hydrated and take precautions to avoid heat exhaustion
What is the hottest month in Prague in Summer?
July is the hottest month in summer in Prague with an average high temperature ranging from 22°C (71.6°F) to 24°C (75.2°F) depending on the local weather. Some afternoons can reach up to near 31°C (88°F) with the record high temperature in Prague during July being 36°C (97°F).
is Prague warmer than London in summer?
Since I divide my time between London and Prague I’m often asked if Prague is warmer than London in summer. I would say that on average, Prague is much warmer than London in the summer (June-August).
Prague’s average high temperature in the summer is in the low 70s Fahrenheit (around 22°C) while London’s average high temperature in the summer is around 68°F (around 20°C).
The main difference is also humidity level, which has an impact on how the warm temperature feels. Prague humidity is relatively low and the heat feels dry (and fairly easy to withstand), whereas in London where the humidity is on average much higher, it can feel very stifling even during night.
In the last few years, the summers, both in London and Prague were extremely warm with scorchingly hot days and no rain.
How to read the local weather forecast
The local weather forecast uses Celsius (not Fahrenheit) and the temperature given is measured (or predicted) in the shade. This means that if the weather forecast mentions 25 C, it can be easily 30-35 C in the sun.
This is quite a big difference, so if you see anything over 20-25 C in a weather forecast, do plan some activities that will keep you cool, at least during the biggest heat of the day between 1-3 pm.
How much does it rain in Prague in summer?
Even without a weather forecast you can tell when the rain is going to come and what type it will be.
If the weather has been incredibly hot for a few days and the wind is rising and it’s clouding over, expect a quick downpour and heavy showers. The showers are usually over within few minutes (or at least they get more milder), the sun is back and you can carry on with your day. If it’s been hot for a few days, the storms and thunderstorms can be much longer and last for a few hours.
If the weather has been slightly colder and it’s getting windy and clouding over, the rain will be more persistent and perhaps slightly lighter. It will, however last much longer, so it’s wise to revise your plans for indoor activities or at least wear good sturdy shoes and pack rain jacket or an umbrella.
The average rain fall in Prague during summer
The average rain fall in Prague during summer is very low.

How much daylight is in the summer?
The sunrise is at 5 am and the sunset is at 9 pm during summer with nearly extra 40 minutes after the sunset when you can see the light.
The good thing about this time of the year, is that you have a lot of day light as you can easily see light until 9 – 9.30pm ( or nearly 10 pm).
This is great if you are planning a day trip outside Prague or a longer walk.
I always plan my longest day trips for June, July or August as you can do a lot in the day.
As you go through the summer, the light does start to shorten and by the end of August, the day light shifts to approximately 5.30 am to 8.30 pm. This is still plenty of time to fit a very long day trip.

What does Prague’s nature look like in summer?
I thought I’d also mention, what you can expect in the terms on nature, parks and countryside. I only thought about this because for a couple of years, I couldn’t come to Prague in summer and realised that my pictures were missing flowering plants, trees with leaves on and green grass!
Anyway, if you visit Prague in summer, you’ll be pleased to find plenty of flowering gardens, trees with green leaves and grass to sit on in the park. Although the grass might be a bit scorched with the sun if it’s hot for a long time!
Summer hay fever allergies
If you suffer from hay fever allergies, you might like to know that by the beginning of June most trees would have flowered, so the tree pollen should be very low.
However, the most famous Czech tree – the lime tree (it symbolises Czech nationality and it’s usually planted along the roads, streets and in gardens), still continues to flower well into the beginning of July.
You’ll also encounter grass pollen, as grass can flower still in June and July and unfortunately, weed pollen start to flower at the end of June all the way to July and August.
Prague parks and gardens are always well maintained, which means that the grass is regularly cut and the weeds taken out. Most parks and gardens, therefore should be fine for you to visit if you suffer with mild hay fever, but do be prepared to have an alternative plan in case there are some flowering plants or trees that are too strong for you.
If you forget your hay fever medication, or need some, any pharmacy will be able to help you. Not all pharmacist speak English, but if you visit a large pharmacy like the one in the Main Train Station, they might have staff on duty who speak English. Most hay fever medication is also international, so you might recognise the type of medication you normally take.
In Czech hay fever is ‘senna ryma’, in case you need to make yourself understood in Czech.
What to pack for your visit in the summer
You seriously don’t need a lot for your summer visit to Prague! Although the weather is going to be hot, the second layer is always useful, especially in the morning and evening.
I would also pack, a good sun hat, sunglasses and a long light linen shirt, trousers or a skirt. I love to wear an easy to wear a dress, which I wash every night and just leave on a clothes hanger to drip dry in the shower.
It might be tempting to bring just flip flops or summer flats as it’s going to be very hot, but the Prague cobbles are very hard (and uneven surface) to walk on, so pair of comfy trainers or padded shoes are a must. You can find other tips on what to pack in this blog post.
