Prague Weather by Month: Average Temperatures and Best Times

Quick answer

For optimal city walking, May, June, and September provide the most reliable conditions with temperatures between 18°C and 23°C and approximately 14 hours of daylight. July and August are the warmest but see the highest rainfall due to sudden storms and the largest crowds near Charles Bridge. January and February are the coldest and driest, ideal for lower hotel rates in areas like Žižkov if you can tolerate averages of -2°C.

Prague monthly weather table

January

Expect grey skies and biting winds when walking across the Mánes Bridge. Temperatures average 0°C, often dropping to -5°C at night. Snow is common but rarely accumulates deep in the city centre. Wear thermal base layers, a wool coat, and waterproof boots with grip for icy cobblestones. January is the cheapest month for accommodation near Náměstí Míru, with 4-star hotels often priced around 1,500 CZK ($65) per night. Indoor attractions like the National Museum (250 CZK entry) are preferred over long outdoor walks.

February

February remains cold with an average high of 4°C. The air is often dry, but the wind chill in open spaces like Letná Park can feel significant. Pack a heavy scarf and insulated gloves. While not suitable for hiking the Divoká Šárka trails due to mud and ice, it is an excellent time for visiting the Prague Castle complex without the three-hour queues typical of summer. Masopust (carnival) festivals occur this month, involving outdoor parades and fried foods like koblihy.

March

Weather fluctuates wildly as spring begins. One day may reach 15°C, while the next sees sleet. Average highs sit around 9°C. Transition to layered clothing: a mid-weight jacket over a sweater. City walking becomes more viable, though the lack of foliage makes parks look sparse. Most seasonal castles outside the city, such as Karlštejn, remain closed or on restricted weekend hours until April. Carry a compact umbrella as light drizzle is frequent.

April

April brings the first consistent greenery to the Petřín Hill orchards. Highs reach 15°C, but evenings stay brisk at 4°C. This is the start of the beer garden season, though you will likely need a jacket to sit outside at Riegrovy Sady. Planning should account for "April weather" (aprílové počasí), meaning sudden shifts from sun to rain. A trench coat or light puffer jacket is sufficient. Expect moderate crowds around the Astronomical Clock during Easter markets.

May

May is arguably the best month for city walking and hiking. Temperatures average 20°C, and the city is in full bloom. The Prague Spring International Music Festival begins, increasing demand for hotels in Staré Město. Rainfall increases to 60mm, usually as afternoon showers. Pack light trousers and cotton shirts, but keep a waterproof shell handy. This is the peak time to visit the Royal Garden at Prague Castle or hike the Prokopske Valley trails.

June

Early summer brings highs of 23°C and the longest days of the year, with sunset around 21:00. This is excellent for evening walks along the Náplavka riverbank. However, June is one of the wettest months, often experiencing heavy thunderstorms. Humidity increases, making the Metro A line stations feel warm. Wear breathable fabrics like linen or moisture-wicking synthetics. Outdoor festivals, such as United Islands of Prague, are major draws this month.

July

July is the hottest month, with peaks frequently hitting 30°C or higher. The city centre becomes heat-stressed due to the stone architecture and lack of breeze. Seek shade in the Waldstein Garden or take the 17 tram to the Vltava riverside for cooler air. While Prague has no sea beaches, locals use the Žluté lázně riverside area for swimming and volleyball (entry approx. 100 CZK). Pack sunblock and light clothing. Be prepared for high humidity and sudden heavy rain.

August

Conditions mirror July, with average highs of 25°C. The city remains crowded with international tourists. Nightly lows of 14°C make al fresco dining at Vinohrady bistros comfortable. Air conditioning is not universal in older boutique hotels, so check your booking if you are sensitive to heat. This is a prime month for day trips to nearby lakes like Máchovo jezero, roughly 90 minutes away by bus, which serves as a local beach substitute.

September

September offers stable, mild weather with highs of 20°C and significantly less rain than summer (40mm). The "Indian Summer" (babi léto) provides clear blue skies, ideal for photography from the Old Town Bridge Tower. Crowds begin to thin slightly by mid-month. This is the best time for vineyard walks in Troja or hiking in the Bohemian Switzerland National Park (2 hours by train). A light sweater or denim jacket is usually enough for evenings.

October

Autumn colours peak in late October, especially in parks like Stromovka. Highs drop to 14°C, and mornings can be foggy. The Signal Festival of lights takes place this month, requiring warm layers for night-time walking tours. Pack a scarf and a medium-weight coat. Rainfall is low (30mm), making it a reliable month for city exploration before the winter damp sets in. Most seasonal attractions close at the end of this month.

November

November is typically grey, damp, and overcast, with average highs of 7°C. The sun sets early, around 16:15. While not ideal for hiking or beaches, it is a focused time for museum visits and the emerging cafe culture in Karlín. You will need a windproof, waterproof coat. Prices for central accommodation drop significantly compared to September. The lack of light can be gloomy, so plan for indoor activities after 16:00.

December

Temperatures hover near freezing (3°C high, -1°C low). The air feels damp, which increases the chill. Christmas markets at Old Town Square and Wenceslas Square create peak crowd levels despite the cold. Dress in full winter gear: thermal leggings, woollen hats, and insulated gloves. While snow isn't guaranteed, the combination of festive lights and potential dustings of white makes it a popular time for city walking. Mulled wine (svařák) sold at stalls for 60-90 CZK helps manage the cold.

Common mistakes

• Packing only summer clothes for May or June; these months have the highest rainfall and can have cool evenings.
• Wearing thin-soled shoes; Prague’s historic centre is almost entirely uneven cobblestones which transfer cold from the ground in winter and heat in summer.
• Assuming summer is the driest season; July and August actually receive the most millimetres of rain due to storms.
• Forgetting to check tram schedules for seasonal changes; summer often sees maintenance on major lines like the 9 or 22.
• Planning long hikes in November without waterproof gear; trails become extremely slick with mud and decaying leaves.
