A complete guide to Prague weather in June + what to wear
June is a great time to come and visit Prague, since it’s very warm, plenty of sunshine and and you have the most daylight out of the whole year. 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, 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.
What is the weather like in June?
Most days in June are very warm (up to 17-20 C in the shade, but much hotter in the sun), but you’ll still need a second layer in the morning. You might get the occasional heatwave, so it can be a little challenging to stay cool in the summer in Prague when you want to see everything on your list.
We also get a lot of showers or storms in June. These are usually over very quickly, so it’s best to hide in a shop or have a coffee and then continue with your walk, rather than trying to battle against the rain with an umbrella.
PLANNING YOUR TRIP
Weather temperatures in June
- Average High Temperature: 21°C to 23°C (70°F to 73°F)
- Average Low Temperature: 11°C to 13°C (52°F to 55°F)
- Overall Average Temperature: Around 17°C (63°F)
Expect the temperatures to be the lowest during night and early in the morning and then progressively rising to the highest temperatures between 12-3 pm and then staying warm until the sunset, when they start to cool down again.
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.
How does the weather change during June in Prague?
Generally speaking, the weather is getting hotter and hotter as you progress through the June, but in recent years the weather was very unpredictable. It can be on a colder side one week and a heat wave the next week.
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 20 C, it can be easily 25-30 C in the sun.
This is quite a big difference, so if you see anything over 20 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.
The average rain fall in June
Prague has an average rainfall of about 67 mm to 88 mm (2.6 to 3.5 inches) for the month. Rain typically falls over approximately 13 to 17 days in June, which makes it one of the wetter months of the year.
This sounds like a lot, but often it rains during night and by morning it’s warm and dry again. Showers are usually moderate and often occur as brief summer storms or light rain throughout the day.
How to predict the rain and the type of rain
The summer storms are usually easy to spot, as the clouds get darker and you might even hear thunder before the first drop of rain. It’s best to run for cover, because even if you have an umbrella, the rain could be so strong that you’ll end up wet no matter what.
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 sunshine days in June
Prague usually gets around 7 to 9 full sunny days in June. The rest of the days are typically a mix of sunny, partly cloudy and overcast conditions, but it’s still nice and warm.
Day light in June
The sunrise in June is at 5 am and the sunset is at 9 pm at the beginning of the month. From the middle of June, the sunset moves to 21.15 pm until the end of the month, whilst the sunrise stays at 5 am (moving only by 10 minutes in the middle of the month to 4.50 am).
June is the best month for the longest days with between 16 – 16,5 hrs of a day light each day. I plan most of my long day trips out from Prague for June, because it’s great to know that I have enough time to see everything or do a long hike.

What does Prague’s nature look like in June?
By June, Prague is full of colour – everything is flowering and the parks and streets are green with trees, plants and grass. Most gardens will have summer flowers already flowering and annual bedding flowers will decorate house windows, public parks and street basket displays.
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 unfortunately, weed pollen start to flower at the end of June all the way to late summer.
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 June
Although the weather is going to be very warm, the second layer, such as light summer jacket, light cardigan, sweatshirt or a shirt is always useful, especially in the morning and evening.
I also always pack a good sun hat, sunglasses and a long light linen shirt, trousers or a long dress or a skirt. Since it can still be quite chilli in the morning I also pack a pair of leggings which I wear under my dress or skirt and then take them off when it gets warm during the day.
I’ve also learned that an umbrella is a super useful at this time of the year – not only for against the rain, but also against the sun! When it’s very sunny and you still want to walk everywhere, it comes in handy as an your very own portable shade!
It might be tempting to bring just flip flops or summer flats as it can be quite warm, but the Prague cobbles are very hard (and uneven surface) to walk on, so pair of comfy trainers or padded shoes are a must. Over the last few years, especially when the weather was too hot to even wear plastic trainers, I ended up wearing light canvas shoes (with extra insoles for padding) with very thin cotton socks. My feet were still warm, but not as much as wearing regular trainers.

June Historic weather data
Warmest June:
The warmest June on record in Prague was in 2019, when the average monthly temperature reached 20.7°C (69.3°F), making it the hottest June since records began in 1961. That year saw several days with temperatures above 30°C (86°F), and a persistent heatwave affected much of Central Europe.
The hottest day ever recorded in Prague in June was on June 19, 2022, when temperatures reached 37.9°C (100.2°F) at the Prague-Klementinum weather station. This extreme heat set a new record for the highest June temperature in Prague since records began.
Coldest June:
One of the coldest Junes in Prague occurred in 1974, when the average temperature was significantly below normal, with many days remaining below 15°C (59°F). Nighttime temperatures occasionally dropped below 10°C (50°F), and the month felt more like early spring than summer.
The coldest ever recorded day in June in Prague occurred on June 1, 1985, when the temperature dropped to 2.0°C (35.6°F) at the Prague-Klementinum weather station. Such low temperatures are extremely rare for June in Prague, and this record stands out as an exceptional cold snap for the early summer period
Flooding: June can bring heavy rain and thunderstorms. In June 2013, Prague experienced significant flooding due to persistent rain, causing the Vltava River to rise and prompting evacuations and closures of parts of the city, including the Prague Metro and some bridges.
Storms: Severe storms are not uncommon in June. For example, in June 2021, Prague saw intense thunderstorms with hail and strong winds, leading to local flooding and some property damage.
Droughts: Some Junes have been marked by drought and very little rainfall, contributing to water shortages and affecting agriculture. The period from 2015 to 2021 included some of the driest and hottest Junes on record.
